  • Which workflow engine should I chose for implementing a dynamic reconfiguration of workflows?

    - by Raya
    I want to be able to interrupt a running workflow instance, say when a new activity is about to be invoked, and extract information both about the structure of the workflow and the data in the particular instance. Then I will consult with an external system and according to its response I will possibly alter the behaviour of the workflow. The options I would like to have are addition/removal of activities and altering parameters for the activities to be invoked. I am currently struggling with the engine it's best to go with. I have looked at WWF, Apache ODE, Oracle Workflow and Active BPEL and as far as I understand they can all provide me with the options I need. I would really appreciate any recommendations on which one will be the easiest to work with for my purpose and any restrictions either of the above might have that would prevent me from reaching my goal. Thanks

  • Is it possible to use Sphinx search with dynamic conditions?

    - by Fedyashev Nikita
    In my web app I need to perform 3 types of searching on items table with the following conditions: items.is_public = 1 (use title field for indexing) - a lot of results can be retrieved(cardinality is much higher than in other cases) items.category_id = {X} (use title + private_notes fields for indexing) - usually less than 100 results items.user_id = {X} (use title + private_notes fields for indexing) - usually less than 100 results I can't find a way to make Sphinx work in all these cases, but it works well in 1st case. Should I use Sphinx just for the 1st case and use plain old "slow" FULLTEXT searching in MySQL(at least because of lower cardinality in 2-3 cases)? Or is it just me and Sphinx can do pretty much everything?

  • How to simulate :active css pseudo class in android on non-link elements?

    - by chas s.
    I'd like to be able to mimic the behavior of the :active pseudo class on all elements in Android webkit. Currently, the :active syntax only works on a elements (links). Nearly all of the actionable elements in the app I'm working on are something other than a standard link tag. iOS webkit supports :active on all elements. /* works on both android iOS webkit */ a:active { color: blue; } /* works on iOS webkit, does not work on android webkit */ div:active { color: red; } I've found a couple of resources [1,2] that solve similar problems, but they're both a bit heavy, and I'm wondering if there's a lighter weight solution that I'm just not able to find. http://cubiq.org/remove-onclick-delay-on-webkit-for-iphone http://code.google.com/intl/ro-RO/mobile/articles/fast_buttons.html

  • XPath _relative_ to given element in HTMLUnit/Groovy?

    - by Misha Koshelev
    Dear All: I would like to evaluate an XPath expression relative to a given element. I have been reading here: http://www.w3schools.com/xpath/default.asp And it seems like one of the syntaxes below should work (esp no leading slash or descendant:) However, none seem to work in HTMLUnit.

  • How to return dynamic CSS with ASP.NET MVC?

    - by Morten Mertner
    I need a solution that lets me accomplish the following: Returning CSS that is dynamically generated by an action method Choosing CSS file depending on request parameter or cookie Using a tool to combine and compress (minify) CSS I am currently considering why there is no CssResult in ASP.NET MVC, and whether there might be a reason for its absence. Would creating a custom ActionResult not be the best way to go about this? Is there some other way that I've overlooked to do what I need? Any other suggestions or hints that might be relevant before I embark on this task will also be appreciated :)

  • How to generate a PDF of dynamic HTML content?

    - by chris Frisina
    I am trying to be able to allow users to generate content dynamically, and have that information be in a , and then allow that specific to be exportable to a pdf. I have got Joomla up and running (with the appropriate mySQL and ANT) locally with the Web2PDF extension, but how would I get those running on my domain (hosted by Dreamhost). Are there any other approaches you might recommend. The content is generated by JS and JQuery, and formatted with CSS and HTML. Other considerations: Web2PDF generates a PDF on the entire content, (pulling the entire page's HTML, not just the specific <div>.

  • How do I dynamically update an instance array to hold a list of dynamic methods on instantiation?

    - by Will
    I am trying to dynamically define methods based on xml mappings. This works really well. However I want to create an instance variable that is a array of the dynamically defined methods. My code looks something like this def xml_attr_reader(*args) xml_list = "" args.each do |arg| string_val = "def #{arg}; " + " xml_mapping.#{arg}; " + "end; " self.class_eval string_val xml_hash = xml_list + "'#{arg}'," end self.class_eval "@xml_attributes = [] if @xml_attributes.nil?;" + "@xml_attributes = @xml_attributes + [#{xml_list}];" + "puts 'xml_attrs = ' + @xml_attributes.to_s;" + "def xml_attributes;" + " puts 'xml_attrs = ' + @xml_attributes.to_s;" + " @xml_attributes;" + "end" end So everything works except when I call xml_attributes on an instance it return null (and prints out 'xml_attrs = '). While the puts before the definition actually prints out the correct array. (when I instantiate the instance)

  • Is there a .NET BCL class to help with hand-rolled property path binding?

    - by Wayne
    WPF and Silverlight have a data binding model whereby I can provide a Binding with a Path which comprises a dot-notation of property accessors down from a DataContext to a specific value inside a complex object graph (eg. MyDataContext.RootProperty.SubProperty.Thing.Value) I have a (non-UI) requirement to accept such a path expressed as a simple string, and to use reflection on an object which is (hopefully) of a type which exposes the right property getters and setters in order to read and/or write values to those properties. Before I go off and start writing the parser and reflection code, is there a handy Framework 3.5 BCL class to help with this?

  • Pass existing model into AJAX PartialViewResult

I'm guessing I somehow have to pass the model to the SHIPDEL Action first. I couldn't find an @Ajax.ActionLink overload that would allow this. public PartialViewResult SHIPDEL() { return PartialView("AJAX_Views/_ShipDel", this.ModelState); } In the _ShipDel Partial View I need to expose the CmpAdrsSh properties so the model validates in the POST Action. The model is empty at this point. How do I pass the existing vM model into the _ShipDel partial view? Thank you,

  • How do I call a function name that is stored in a hash in Perl?

    - by Ether
    I'm sure this is covered in the documentation somewhere but I have been unable to find it... I'm looking for the syntactic sugar that will make it possible to call a method on a class whose name is stored in a hash (as opposed to a simple scalar): use strict; use warnings; package Foo; sub foo { print "in foo()\n" } package main; my %hash = (func => 'foo'); Foo->$hash{func}; If I copy $hash{func} into a scalar variable first, then I can call Foo->$func just fine... but what is missing to enable Foo->$hash{func} to work? (EDIT: I don't mean to do anything special by calling a method on class Foo -- this could just as easily be a blessed object (and in my actual code it is); it was just easier to write up a self-contained example using a class method.) EDIT 2: Just for completeness re the comments below, this is what I'm actually doing (this is in a library of Moose attribute sugar, created with Moose::Exporter): # adds an accessor to a sibling module sub foreignTable { my ($meta, $table, %args) = @_; my $class = 'MyApp::Dir1::Dir2::' . $table; my $dbAccessor = lcfirst $table; eval "require $class" or do { die "Can't load $class: $@" }; $meta->add_attribute( $table, is => 'ro', isa => $class, init_arg => undef, # don't allow in constructor lazy => 1, predicate => 'has_' . $table, default => sub { my $this = shift; $this->debug("in builder for $class"); ### here's the line that uses a hash value as the method name my @args = ($args{primaryKey} => $this->${\$args{primaryKey}}); push @args, ( _dbObject => $this->_dbObject->$dbAccessor ) if $args{fkRelationshipExists}; $this->debug("passing these values to $class -> new: @args"); $class->new(@args); }, ); } I've replaced the marked line above with this: my $pk_accessor = $this->meta->find_attribute_by_name($args{primaryKey})->get_read_method_ref; my @args = ($args{primaryKey} => $this->$pk_accessor); PS. I've just noticed that this same technique (using the Moose meta class to look up the coderef rather than assuming its naming convention) cannot also be used for predicates, as Class::MOP::Attribute does not have a similar get_predicate_method_ref accessor. :(

  • How to use Code Igniter to show Dynamic images via javascript(jQuery).

    - by aaroninfidel
    You can use the URL helper in Code Igniter to load CSS and Javascript with the base_url() method, but what if you have images dynamically being placed into your HTML via javascript? for example in my javascript file I've got var arrowimages={down:['downarrowclass', 'images/down.png', 23], right:['rightarrowclass', 'images/right.png']} and those images will be placed into whatever menu item I've specified has a drop down menu. but that file is a .js file so obviously the server won't load php inside of it. so, how can I set the base url for the JS? Thanks! -Aaron

  • Fluent NHibernate beginner problem: How to convert single column data to custom class?

I beleive this post http://intellect.dk/post/Implementing-custom-types-in-nHibernate.aspx explains how to solve it for NHibernate. But I am not sure... How do I get this working with Fluent NHibernate?

  • Is there any Prototype Javascript function similar to Jquery Live to trace dynamic dom elements?

    - by Wbdvlpr
    Hi Event.observe(window,"load",function() { $$(".elem_classs").findAll(function(node){ return node.getAttribute('title'); }).each(function(node){ new Tooltip(node,node.title); node.removeAttribute("title"); }); }); Using above method, I can retrieve all elements having ".elem_class" and apply some javascript functions on them. But I have a modal/popup box which has some elements also having ".elem_class" and these dont get in the scope of findAll/each as they are loaded into the dom thru ajax. How do I apply the same to dynamically loaded elements as well? I am using Prototype Library. (I have used JQuery's Live function which keeps track of all future elements, but need to achieve something similar using Prototype) Thanks.

  • I get NaN when I try to insert some HTML into a DIV element with jQuery

    - by Ankur
    I am tring to display a text box when a element of class numObj is clicked. For some reason I get NaNNaNaNaNNaNNaNaNaN where I expect to the see the result of the searchForm variable in the code below. I know that NaN stands for Not a Number. What I don't understand is why is Javascript expecting a number? I can't understand why it cares. $(".numObj").live('click',function(){ var preId = $(this).attr('preId'); var arrayPos = $(this).attr('numArrayPos'); alert(preId +" "+arrayPos); var searchForm = "<table border='0' cellspacing='0' cellpadding='4' id='add-tag2'>"+ +"<tr class='normal'><td bgcolor='#EEEEEE' valign='bottom' nowrap='nowrap'><span class='normal-small'>"+ +"<input name='predicate-name2' type='text' class='normal' id='predicate-name2' size='4' />"+ +"</span></td>"+ +"<td bgcolor='#EEEEEE' valign='bottom' nowrap='nowrap'><span class='normal-small'>&lt;=</span></td>"+ +"<td bgcolor='#EEEEEE' valign='bottom' nowrap='nowrap'>x</td>"+ +"<td valign='bottom' bgcolor='#EEEEEE'>&lt;=</td>"+ +"<td valign='bottom' bgcolor='#EEEEEE'><span class='normal-small'>"+ +"<input type='text' name='object-object2' id='object-object2' class='normal' size='4' />"+ +"</span></td>"+ +"</tr>"+ +"</table>"; $(".numObj").filter("[preId='"+preId+"']").filter("[numArrayPos='"+arrayPos+"']").html(searchForm); }); The generated code that has the numObj class looks something like this <td><div class="numObj" preid="73" numarraypos="5"><span class="normal">585.0</span></div></td>

  • How can I use Three20 to create a dynamic TTThumbsViewController that feeds from a website directory?

    - by Cory Robbins
    Hello, I'm pretty new to the iPhone developing scene, and I am designing an app for a high school band program. Part of the app needs to be an image gallery that retrieves photos from a directory on the band's website and lists them in the thumbnail view. I can't figure out how to create a thumsview that isn't directly linked to specific pictures. I currently have this setup to work with a UIWebView that points to a PHP photo album designed to look like the iPhone Photo Album. This method works, but it is not ideal, and the navigation is obviously a bit less than what would be expected. Is Three20 the right tool for this job? If not, what should I be using? Thanks!

  • How can I specify a dynamic height for an ImageView?

    - by kefs
    I have an ImageView at the top of my display that looks like the following: +----------------------------------------------+ ¦ ImageView +--------------+ ¦ ¦ ¦ ¦ ¦ ¦ ¦ Actual image ¦ ¦ ¦ ¦ ¦ ¦ ¦ ¦ ¦ ¦ ¦ ¦ ¦ ¦ ¦ +--------------+ ¦ +----------------------------------------------+ Below this, I have a series of Buttons and TextViews.. I would like the ImageView's height to dynamically increase depending on the max height of the screen. I'm aligning the layout containing the buttons along the bottom of edge of the screen, and I would like the rest of the screen taken up by the above ImageView. Also, since the ImageView contains a centered image, I would also like to set min height, and a scrollbar if the screen is too small to display the imageview and the buttons below. Thanks! Is this possible?

  • How to Refresh / Reload a KML layer in OpenLayers. Dynamic KML Layer.

    - by Ozaki
    TLDR See my answer below on how to refresh the layer. So far I have tried action function as follows: function RefreshKMLData(layer) { layer.loaded = false; layer.setVisibility(true); layer.redraw({ force: true }); } set interval of the function: window.setInterval(RefreshKMLData, 5000, KMLLAYER); the layer itself: var KMLLAYER = new OpenLayers.Layer.Vector("MYKMLLAYER", { projection: new OpenLayers.Projection("EPSG:4326"), strategies: [new OpenLayers.Strategy.Fixed()], protocol: new OpenLayers.Protocol.HTTP({ url: MYKMLURL, format: new OpenLayers.Format.KML({ extractStyles: true, extractAttributes: true }) }) }); the url for KMLLAYER with Math random so it doesnt cache: var MYKMLURL = var currentanchorpositionurl = 'http://' + host + '/data?_salt=' + Math.random(); I would have thought that this would Refresh the layer. As by setting its loaded to false unloads it. Visibility to true reloads it and with the Math random shouldn't allow it to cache? So has anyone done this before or know how I can get this to work? TLDR See my answer below on how to refresh the layer.

    I have simple search page i want to filter the results. var TransactionStats = from trans in context.ProductTransactionSet.Include("SPL") select new { trans.InvoiceNo, ProductGroup = from tranline in trans.ProductTransactionLines group tranline by tranline.ProductTransaction.TransactionID into ProductGroupDetil select new { TransactionDateTime = ProductGroupDetil.Select (Content => Content.TransactionDateTime) } }; I want to use TransactionDateTime in where clause when required. if (_FilterCrieteria.DateFrom.HasValue) { TransactionStats.Where ( a => a.ProductGroup.Where ( dt => dt.DateofTransaction >= _FilterCrieteria.DateFrom && dt.DateofTransaction >= _FilterCrieteria.DateFrom ) ) } Can any one correct the syntax?

  • Should I be using Expression Blend to design really dynamic UIs?

    - by Robert Rossney
    My company's product is, at its core, a framework for developing metadata-driven UIs. I don't know how to characterize it less succinctly than that, and hope I won't need to for purposes of this question, but we'll see. I've been trying to come up to speed on WPF, and have been building UI prototypes here and there, and recently I decided to see if I could use Expression Blend to help with the design of these UIs. And I'm pretty mystified at this point. It appears to me as though Expresssion Blend is designed with the expectation that you already know all of the objects that are going to be present in the UI at design time. But our program generates these object dynamically at runtime. For instance, a data row might be presented in a horizontal StackPanel containing alternating TextBlocks (for captions) and TextBoxes (for data fields). The number of these objects depends on metadata about the number of columns in the data row. I can, pretty readily, write code that runs through a metadata record and populates a StackPanel dynamically, setting up the binding of all of the controls to properties in either the data or metadata. (A TextBox's Width might be bound to metadata, while its Text is bound to data.) But I can't even begin to figure out how to do something like this in Expression Blend. I can manually create all these controls, so that I have a set of controls that I can apply styles to and work out the visual design of the app, but it's really a pain to do this. I can write code that goes through my data model and emits XAML for all these controls, I suppose, and then copy and paste it. But I'm going to feel really stupid if it turns out there a way to do this sort of thing in Expression Blend and I've dropped back and punted because I'm too dim to figure out the right way to think of it. Is this enough information for someone to try formulating an answer?

  • which jquery plugin can do the dynamic smooth vertical menu scroll?

    - by helltohigh
    ok i'm new to jquery, but how can i do a feed like the one at twitter.com where they have the "top tweets" update with the latest tweet by scrolling the whole menu down just enough space to allow the new item to fade into the top spot? easy to do? do i need a plugin? i looked around and what i don't want is just a carousal type plugin that just loops in a cirle. i want to add a new news feed item dynamically like in the twitter top tweets. thanks
