  • Dismiss android activity displayed as Popup

    - by Sit
    So i have a service, that starts an activity displayed as a Popup thank's to "android:style/Theme.Dialog" This Activity shows a Listview, with a list of application. On each element of the listview, there is a short description of the application, and two buttons. 1 for launching the application 2 for displaying a toast with more informations. Here is the code in my service : it starts the activity Intent intent = new Intent(this, PopUpActivity.class); intent.addFlags(Intent.FLAG_DEBUG_LOG_RESOLUTION); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); getApplicationContext().startActivity(intent); this activity uses a custom layout, with a listview, adapted with a custom ArrayAdapter In this adaptater, i've put an action on the start button in order to start the current application Button lanceur = (Button) v.findViewById(R.id.Buttonlancer); lanceur.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { p.start(mcontext); } }); with p.start, i start the application. But now, if i press "back" from the application, i go back to the popup... and i can start another application. I don't want it to be possible. That's why i wish i could dismiss/destroy/finish my PopupActivity, but i can't manage to do it with the code i have.

  • Which method of 'clearfix' is best?

    - by Pickledegg
    I have the age old problem of a div wrapping a 2 column layout. My sidebar is floated so my container div fails to wrap the content & sidebar. <div id="container"> <div id="content"> </div> <div id="sidebar"> </div> </div> There seem to be numerous methods of fixing the clear bug in FF: <br clear="all"/> overflow:auto overflow:hidden etc. But in my situation, the only one that seems to work correctly is the <br clear="all"/> solution, which is a little bit scruffy. overflow:auto gives me nasty scrollbars, and overflow:hidden must surely have side effects. Also, apparently IE7 is supposed to not suffer from this problem due to its incorrect behaviour, but again, in my situation its suffering the same as FF. Whats the most reliable/best practice method currently available to us?

  • Clear listview content?

    - by Slash
    I have a little problem with listview. How do i clear a listview content, knowing that it has a custom adapter? edit : the custom adapter class extends BaseAdapter, it looks like this : import android.app.Activity; import android.content.Context; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.BaseAdapter; import android.widget.TextView; public class MyAdapter extends BaseAdapter { private Activity activity; private String[] data; private static LayoutInflater inflater=null; public MyAdapter(Activity _a, String[] _str) { activity = _a; data = _str; inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE); } public static class ViewHolder{ public TextView text; } @Override public int getCount() { return data.length; } @Override public Object getItem(int position) { return position; } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View view, ViewGroup parent) { View v = view; ViewHolder holder; if(v == null) { v = inflater.inflate(R.layout.rowa, null); holder=new ViewHolder(); holder.text=(TextView)v.findViewById(R.id.dexter); v.setTag(holder); }else{ holder=(ViewHolder)v.getTag(); } holder.text.setText(data[position]); return v; } }

  • Can someone please explain Cursor in android ?

    - by Prabhat
    Can some one explain how the cursor exactly works ? Or the flow of the following part of the code ? I know that this is sub activity and all but I did not understand how Cursor works exactly. final Uri data = Uri.parse("content://contacts/people/"); final Cursor c = managedQuery(data, null, null, null, null); String[] from = new String[] { People.NAME }; int[] to = new int[] { R.id.itemTextView }; SimpleCursorAdapter adapter = new SimpleCursorAdapter(this,R.layout.listitemlayout, c, from, to); ListView lv = (ListView) findViewById(R.id.contactListView); lv.setAdapter(adapter); lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View view, int pos, long id) { c.moveToPosition(pos); int rowId = c.getInt(c.getColumnIndexOrThrow("_id")); Uri outURI = Uri.parse(data.toString() + rowId); Intent outData = new Intent(); outData.setData(outURI); setResult(Activity.RESULT_OK, outData); finish(); } }); Thanks.

  • facebook comments ajax

    - by Shunsho
    I have a function that load a jquery ui accordion (differents accordions based on different id) When I click on the tab titled "Facebook Comments" I do: $("#myaccordion").bind('accordionchange', function(event, ui) { id = $("#myaccordion").data('id'); switch (ui.newHeader.text()) { case "Facebook Comments": displayFb(id); break; } }); The "displayFB" function is: function displayFb(id){ $.get('/fbcomments/' + id, function(data) { $("#facecomm").append(data); }); } Where www.myweb.com/fbcomments/id is: <div id="fb-root"></div> <script>(function(d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "//connect.facebook.net/es_ES/all.js#xfbml=1"; fjs.parentNode.insertBefore(js, fjs); }(document, 'script', 'facebook-jssdk'));</script> <div class="fb-comments" data-href="<?php echo '/fbcomments/'.$id ?>" data-num-posts="10" data-width="220"></div> When I load the homepage, then choose an accordion, then open a Facebook Comments, it works perfect. If I reload the page and choose another accordion, work perfect again. The problem is when I choose another accordion or the same again without reload the whole page. The accordions loads very well, all the data on them (some tabs of images, text, videos, etc), but the facebook comments don't appear. I tried: loading the #fb-root and facebook comment <script> on the main layout....doesn't work. adding FB.XFBML.parse(); into displayFB function....doesn't work adding FB.XFBML.parse(); into a $(document).ready(function(){} ...doesn't work. Thank you for reading and try to help!!

  • <h:selectOneMenu> ValueChangeListener Problem

    - by Ehsun
    I have two <h:selectOneMenu> tags on my form like this: <h:outputText value="#{lbls.incomeType}:"/> <h:selectOneMenu id="incomeType" label="#{lbls.incomeType}" onchange="submit();" valueChangeListener="#{price.earnTypeValueChanged}" immediate="true"> <f:selectItems value="#{price.earnTypes}"/> <f:converter converterId="ir.khorasancustoms.EarnTypeConverter"/> </h:selectOneMenu> <h:message for="incomeType" infoClass="info" errorClass="error" warnClass="warning" fatalClass="fatal"/> <h:outputText value="#{lbls.earnAttribute}:"/> <h:selectOneMenu id="earnAttribute" label="#{lbls.earnAttribute}" value="#{price.price.earnAttribute}"> <f:selectItems value="#{price.earnAttributes}"/> <f:converter converterId="ir.khorasancustoms.EarnAttributeConverter"/> </h:selectOneMenu> <h:message for="incomeType" infoClass="info" errorClass="error" warnClass="warning" fatalClass="fatal"/> <h:messages globalOnly="true" layout="table" infoClass="info" warnClass="warning" errorClass="error" fatalClass="fatal"/> <h:button value="#{lbls.cancel}" outcome="index"/> <h:commandButton value="#{lbls.ok}" action="#{price.save}"/> the handler in the bean looks like this: public void earnTypeValueChanged(ValueChangeEvent event) { EarnType newEarnType = (EarnType) event.getNewValue(); earnAttributes = newEarnType.getAttributes(); FacesContext.getCurrentInstance().renderResponse(); } Everything works fine, except the user needs to press the OK button twice because the first one fires the earnTypeValueChanged. How is that caused and how can I fix it? Update 1: public void earnTypeValueChanged(ValueChangeEvent event) { EarnType oldEarnType = (EarnType) event.getOldValue(); EarnType newEarnType = (EarnType) event.getNewValue(); earnAttributes = newEarnType.getAttributes(); if (!newEarnType.equals(oldEarnType)) { FacesContext.getCurrentInstance().renderResponse(); } }

  • sIFR 3 randomly placing text on a single line in FF3.6

    - by bigsweater
    Hello, sIFR 3 is behaving strangely in Firefox. The actual sIFR flash element is set within a box that is 412px wide. In IE, Chrome, Safari, etc., the with of the Flash element is a consistent 412px; however, in Firefox, the Flash element is briefly as wide as the Body element, before correcting itself. When the page finishes loading, sometimes the Flash element remains that wide, breaking the layout (the Flash text flows underneath the sidebar to the right). Setting a width in the CSS for the .sIFR-flash element causes it to remain the proper 412px wide, but the text doesn't wrap at all--it just cuts off at the right edge, and the height of the flash element remains one line high. The markup is simple; it's just an h2 within a div. My sIFR code: var clerkenwell = { src: '/flash/sifr.swf' }; sIFR.activate(clerkenwell); sIFR.replace(clerkenwell, { selector: '.post h2', css: '.sIFR-root { color: #1899c4; text-transform:uppercase; font-size:30px; }', transparent: 'true', }); Setting forceWidth: 'true', just causes the same problem as using a CSS width on the .sIFR-flash element. So: how can I get the sIFR text to remain as wide as its containing element while allowing for line breaks in Firefox? Thanks for any and all help!

  • Web page for IPhone - Large fonts instead of scrolling?

    - by chris_l
    I'm planning the layout of my web page, which should also be usable on the IPhone. I don't really have much experience with the IPhone yet - I just installed the IPhone Simulator on my Mac. The page's contents are flexible, so I think it would be better to use this flexibility to avoid that the user has to scroll around the entire page. Especially I have A header and a sidebar that will be used all the time to perform several actions. A main content area with a number of elements (e.g. images). The UI would stay usable pretty well, if the number of elements shown at one time is reduced for a small screen (e.g. by JavaScript). It would also be okay to make the main content area scrollable (as opposed to the entire page). The problem: If I simply display the page on the IPhone, it uses an extremely small font size, so that users must zoom in first, and then scroll around - so that they can't see the header and sidebar all the time. What's the best way to deal with this situation? Just leave it this way (very small fonts), because users expect that behaviour on the IPhone? Increase the font size (by specifying it in em or px or with xx-large, or what would be the best way?), if I detect - somehow - that it's being displayed on the IPhone. Or is there some way to restrict the viewport size to the screen size, and make it zoom in automatically? I think that would be the easiest solution in my case. Or ...?

  • "Ghost" values in PHP/Smarty.

    - by Kyle Sevenoaks
    I've been working on a site for a while changing the layout and skin of a webshop checkout process. I've noticed that if you go all the way through the process until the last page, then click the link to go back to the view products page, the delivery method price displays underneath the navigation buttons, until you refresh and it goes away again. I've downloaded both sourced from the browser (Chrome, but this bug applies to all browsers) and used a file difference tool to display the differences, the result being only: < error.html vs > normal.html 34c34 < <link href="gzip.php?file=167842c1496093fbcd391b41cf7b03da.css&time=1272272181" rel="Stylesheet" type="text/css"/> --- > <link href="gzip.php?file=167842c1496093fbcd391b41cf7b03da.css&time=1272272348" rel="Stylesheet" type="text/css"/> Which is just the way it zips up the CSS stylesheets. (afaik) Has anyone ever encountered such a problem, or anything similar? Normal: Error: I can't even hazard a guess as to what is causing this, at all. I've searched over Google for anything and come up with nothing. What could be causing this? The site in question is Euroworker.no. HTML @ Pastebin. Smarty snippet: {if !$CANONICAL} {canonical}{self}{/canonical} {/if} <link rel="canonical" href="{$CANONICAL}" /> <!-- Css includes --> {includeCss file="frontend/Frontend.css"} {includeCss file="backend/stat.css"} {if {isRTL}} {includeCss file="frontend/FrontendRTL.css"} {/if} {compiledCss glue=true nameMethod=hash} <!--[if lt IE 8]> <link href="stylesheet/frontend/FrontendIE.css" rel="Stylesheet" type="text/css"/> {if $ieCss} <link href="{$ieCss}" rel="Stylesheet" type="text/css"/> {/if} <![endif]--> Thanks.

  • Using AJAX in Rails: How do I change a button as soon as it's clicked?

    - by sdc
    Hey! I'm teaching myself Ruby, and have been stuck on this for a couple days: I'm currently using MooTools-1.3-compat and Rails 3. I'd like to replace one button (called "Follow") with another (called "Unfollow") as soon as someone clicks on it. I'm using :remote = true and have a file ending in .js.erb that's being called...I just need help figuring out what goes in this .js file The "Follow" button is in a div with id="follow_form", but there are many buttons on the page, and they all have an id = "follow_form"...i.e. $("follow_form").set(...) replaces the first element and that's not correct. I need help replacing the button that made the call. I looked at this tutorial, but the line below doesn't work for me. Could it be because I'm using MooTools instead of Prototype? $("follow_form").update("<%= escape_javascript(render('users/unfollow')) %") ps. This is what I have so far, and this works: in app/views/shared: <%= form_for current_user.subscriptions.build(:event => @event), :remote => true do |f| %> <div><%= f.hidden_field :event %></div> <div class="actions"><%= f.submit "Follow" %></div> <% end %> in app/views/events/create.js.erb alert("follow!"); //Temporary...this is what I'm trying to replace *in app/controllers/subscriptions_controller.rb* def create @subscription = current_user.subscriptions.build(params[:subscription]) @subscription.save respond_to do |format| format.html { redirect_to(..) } format.js {render :layout} end Any help would be greatly, greatly appreciated!

  • passing reference of class to another class android error

    I recently asked the precursor to this question and had a great reply. However, when i was working this into my android application i am getting an unexpected error and was wondering if everyone could take a look at my code and help me see what i am doing wrong. Link to the initial question: passing reference of class to another class My ERROR: "The constructor ConnectDevice(new View.OnClickListener(){}) is undefined" The above is an error detected by eclipse. Thanks in advance! Below are My code snippets: public class SmartApp extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.intro); final Button connectDeviceButton = (Button) findViewById(R.id.connectDeviceButton); connectDeviceButton.setOnClickListener( new View.OnClickListener() { @Override public void onClick(View v) { Thread cThread = new Thread(new ConnectDevice(this)); cThread.start(); } }); } } public class ConnectDevice implements Runnable { private boolean connected; private SmartApp smartAppRef; private ObjectInputStream ois; public ConnectDevice(SmartApp smartAppRef) { this.smartAppRef = smartAppRef; } }

  • Expanders inside listbox leaving blank space on collapse

    - by siz
    We have a rather complex UI that is presenting some problems for us. I have a ListBox that contains a set of DataItems. The DataTemplate for each item is an Expander. The header is text, the content of the Expander is a ListBox. The ListBox contains SubDataItems. The DataTemplate for each SubDataItem is an Expander. Here is a simplified XAML in which I reproduce the issue: <ListBox ItemsSource="{Binding Items}"> <ListBox.ItemTemplate> <DataTemplate> <Expander Header="{Binding Header}"> <ListBox ItemsSource="{Binding SubItems}"> <ListBox.ItemTemplate> <DataTemplate> <Expander Header="{Binding SubHeader}"> <Grid Height="40"> <TextBlock Text="{Binding SubText}" /> </Grid> </Expander> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </Expander> </DataTemplate> </ListBox.ItemTemplate> </ListBox> There is a problem with how the layout is produced. If any Expander corresponding to the SubDataItem is expanded, the ListBoxItem containing this ListBox (the Expander.Content in the parent DataTemplate) correctly requests more space. So I can expand all SubDataItems and correctly see my data. However, when I collapse, the space I previously asked to expand, remains blank, instead of being reclaimed by the ListBoxItem. This is a problem because if I have say 10 SubDataItems and happen to expand all of them at the same time and then collapse, there is a significant amount of white space wasting my real estate. How can I force WPF to resize the ListBoxItem to the correct state?

  • Positioning objects in views during re-orientation in iPad

    - by Arni
    iPad Gurus: Apple wants us to support all orientations. I take that to mean that a particular layout should either rotate so that all objects are positioned relatively the same OR, if that doesn't look good, then they ought to be repositioned, OR two views ought to be designed and built. If I rely on the built-in rotation mechanism, the objects either get resized or they straddle the edge of the page in one orientation or the other, or they disappear from view altogether. I can't seem to find the right settings to get the objects to align clearly so they are seen in each orientation. Repositioning leads to a lot of if statements in the View Controller. So I don't think Apple had that in mind. I tried replacing views and even view controllers in "willRotateToInterfaceOrientation" method, but that either causes crashes or the portrait views end up in landscape unexpectedly and vv. Moreover, two view controllers means double the coding for the same view. There must be proper way to handle orientation changes, but I have searched the internet and documentation and sample code in vain for something that works. How is this done properly? Thanks!

  • android costumized button problem with changing text color

    - by alaxid
    Hi, I made a button that changes the background drawable on different states, this way: <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_pressed="true" android:drawable="@drawable/btn_location_pressed" /> <!-- pressed --> <item android:state_focused="true" android:drawable="@drawable/btn_location_pressed"/> <!-- focused --> <item android:drawable="@drawable/btn_location"/> <!-- default --> The problem here is that I'm also trying to change the textColor as I do with the drawable but I'm not being able to. I already tried android:textColor and android:color but the first doesn't work whilst the seconds changes my background. The next code is part of my layout. Regarding to the text color it only works for the normal state text color, thus not changing it to the white one while pressed <Button android:id="@+id/location_name" android:layout_width="fill_parent" android:layout_height="wrap_content" android:paddingTop="5dp" android:background="@drawable/location" android:textSize="15sp" android:textColor="@color/location_color" android:textColorHighlight="#FFFFFF" /> As anybody got a clue? ty! :)

  • Contacts & Autocomplete

    - by Vince
    First post. I'm new to android and programming in general. What I'm attempting to is to have an autocomplete text box pop up with auto complete names from the contact list. IE, if they type in "john" it will say "John Smith" or any john in their contacts. The code is basic, I pulled it from a few tutorials. private void autoCompleteBox() { ContentResolver cr = getContentResolver(); Uri contacts = Uri.parse("content://contacts/people"); Cursor managedCursor1 = cr.query(contacts, null, null, null, null); if (managedCursor1.moveToFirst()) { String contactname; String cphoneNumber; int nameColumn = managedCursor1.getColumnIndex("name"); int phoneColumn = managedCursor1.getColumnIndex("number"); Log.d("int Name", Integer.toString(nameColumn)); Log.d("int Number", Integer.toString(phoneColumn)); do { // Get the field values contactname = managedCursor1.getString(nameColumn); cphoneNumber = managedCursor1.getString(phoneColumn); if ((contactname != " " || contactname != null) && (cphoneNumber != " " || cphoneNumber != null)) { c_Name.add(contactname); c_Number.add(cphoneNumber); Toast.makeText(this, contactname, Toast.LENGTH_SHORT) .show(); } } while (managedCursor1.moveToNext()); } name_Val = (String[]) c_Name.toArray(new String[c_Name.size()]); phone_Val = (String[]) c_Number.toArray(new String[c_Name.size()]); ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line, name_Val); personName.setAdapter(adapter); } personName is my autocompletetextbox. So it actually works when I use it in the emulator (4.2) with manually entered contacts through the people app, but when I use it on my device, it will not pop up with any names. I'm sure it's something ridiculous but I've tried to find the answer and I'm getting nowhere. Can't learn if I don't ask.

  • How to make "int" parse blank strings?

    - by Alex B
    I have a parsing system for fixed-length text records based on a layout table: parse_table = [\ ('name', type, length), .... ('numeric_field', int, 10), # int example ('textc_field', str, 100), # string example ... ] The idea is that given a table for a message type, I just go through the string, and reconstruct a dictionary out of it, according to entries in the table. Now, I can handle strings and proper integers, but int() will not parse all-spaces fields (for a good reason, of course). I wanted to handle it by defining a subclass of int that handles blank strings. This way I could go and change the type of appropriate table entries without introducing additional kludges in the parsing code (like filters), and it would "just work". But I can't figure out how to override the constructor of a build-in type in a sub-type, as defining constructor in the subclass does not seem to help. I feel I'm missing something fundamental here about how Python built-in types work. How should I approach this? I'm also open to alternatives that don't add too much complexity.

  • Android: How to declare global variables?

    - by niko
    Hi, I am creating an application which requires login. I created the main and the login activity. In the main activity onCreate method I added the following condition: public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ... loadSettings(); if(strSessionString == null) { login(); } ... } The onActivityResult method which is executed when the login form terminates looks like this: @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); switch(requestCode) { case(SHOW_SUBACTICITY_LOGIN): { if(resultCode == Activity.RESULT_OK) { strSessionString = data.getStringExtra(Login.SESSIONSTRING); connectionAvailable = true; strUsername = data.getStringExtra(Login.USERNAME); } } } The problem is the login form sometimes appears twice (the login() method is called twice) and also when the phone keyboard slides the login form appears again and I guess the problem is the variable strSessionString. Does anyone know how to set the variable global in order to avoid login form appearing after the user already successfully authenticates? Thanks!

  • Android ProgressDialog inside another dialog

    - by La bla bla
    I'm working on a game using AndEngine, and I need to show the users the list of his Facebook friends. I've created my custom Adatper and after the loading finishes everything works great. I have a problem with the loading it self. The ListView is inside a custom dialog, since I don't really know how to create one using AndEngine, So inside this dialog, I'm running an AsyncTask to fetch the friends' info, in that AsyncTask I'm have a ProgressDialog. The problem is, the ProgressDialog shows up behind the dialog that contains the to-be list (which while loading, is just the title). I can see the ProgressDialog "peeking" behind that dialog.. Any Ideas? Here's some code: FriendsDialog.java private ProgressDialog dialog; //Constructor of the AsyncTask public FriendsLoader(Context context) { dialog = new ProgressDialog(context); dialog.setMessage("Please wait..\nLoading Friends List."); } @Override protected void onPreExecute() { dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); dialog.setView(inflater.inflate(R.layout.loading, null)); dialog.setMessage("Please wait..\nLoading friends."); dialog.show(); } @Override protected void onPostExecute(ArrayList<HashMap<String, Object>> data) { if (dialog.isShowing()) { dialog.dismiss(); } MyAdapter myAdapter = new MyAdapter(context, data); listView = (ListView) findViewById(R.id.list); listView.setAdapter(myAdapter); listView.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> myAdapter, View myView, int myItemInt, long mylng) { String id = (String) listView.getItemAtPosition(myItemInt); listener.onUserSelected(id); dismiss(); } }); }

  • Problem with using Jquery.ajax over .load on Zend

    - by Matthew
    Right now, what i'm trying to do is to replace a label on the front page with a block of html. Right now, the page basically has: <label id="replace"></label> the js currently has: $(document).ready(function(){ $("#replace").load('/test'); }); the Zend class function has: public function indexAction(){ $this->_helper->layout()->disableLayout(); $this->_view->message = "This is from TestController index"; } and finally the index.phtml template simply has: <?php echo $this->message;?> Right now, I want to change the code around so that instead of just replacing that label with the same message, it would do a POST where the function will pull out a parameter, do something (like for instance, go to the database and pull something out with the POST parameter) and then return the message. I've tried editing the js so that it would look like: $.post('/test', {param : "test_param"}, function(data) {$("#replace").html(data);}); or $.ajax({ type: 'POST', url: '/test', data: "{param:test_param}", contentType: "application/json; charset=utf-8", dataType: "json", success: function(data) {$("#replace").html(data);} }); and neither worked. I took a step back and tried to replicate the .load functionality and do: $.ajax({ url: '/test', success: function(data) { $('#replace').html(data); alert('Load was performed.'); } }); and it doesn't work either. Anyone have any tips on how to go about doing this?

  • Grails - Where to store properties related to domains

    - by GalmWing
    This is something I have been struggling about for some time now. The thing is: I have many (20 or so) static arrays of values. I say static because that is how I'm actually storing them, as static arrays inside some domains. For example, if I have a list of known websites, I do: class Website { ... static websites = ["web1", "web2" ...] } But I do this just while developing, because I can easily change the arrays if needed, but what I'm going to do when the application is ready for deployment? In my project it is very probable that, at some point, these arrays of values change. I've been researching on that matter, one can store application properties inside an external .properties file, but it will be impossible to store an array, even futile, because if some array gets an additional value, the application can't recognize it until the name of the new property is added where needed. Another approach is to store this information in the database, but for some reason it seems like a waste to add 20 or more tables that will have just two rows, an id and a name. And the last option, as far as I know, would be an XML, but I'm not very experienced with those. It seems groovy has a way of creating and reading XML files relatively easy, but I don't know how difficult would be to modify an XML whose layout is predefined in the application. Needless to say that storing them in the config.groovy is not an option since any change will require to recompile. I haven't come across some "standard" (maybe a best practice?) way of dealing with these. So the questions is: Where to store these arrays?
