  • Dlink DWA-643 ExpressCard / Atheros AR5008 can't connect to wifi networks

    - by Justin Kelly
    I've just purchased a D-Link DWA-643 Xtreme N ExpressCard Notebook Adapter - but it can't connect to my wireless network The card is listed on the FSF website and - refer links below: http://www.fsf.org/resources/hw/index_html/net/wireless/index_html/cards.html http://www.dlink.com.au/products/?pid=550 Ubuntu see the card as using the Atheros AR5008 chipset - refer image below The card lights up and I can see that available wifi networks using this card - so it seems to 'just work' on ubuntu 12.04 but when i try and connect to my networks - it fails I've tried setting the network to all the different options (WEP, WPA2, no encryption, etc.. b/g/n ) but ubuntu sill cant connect to it I've also installed wicd but still couldn't connect Has anyone got a DWA-643 to work in Ubuntu? Or does anyone have any suggestion on how to get it to connect?? Any help would be greatly appreciated Note: the laptop has built in wifi but its broadcom, works but with dialup speed connection - and i've had nothign but trouble using the boardcom drivers so purchased the FSF recommended PCI expresscard as i hoped it would 'just work' on the latest Ubuntu i've have tried to disable the built in wifi - broadcom - but even with the broadcom uninstall and unavailable it didnt help the dlink to connect previously I had MAC address filtering on the router - i've added the dlinks MAC - and also disabled MAC address filtering - still no luck lspci output below: 18:00.0 Network controller: Atheros Communications Inc.

  • Ubuntu server 9.10 freezes up after ~10 minutes

    - by Matt Williamson
    I just upgraded my Ubuntu server from 9.04 to 9.10 and after about 10 minutes it locks up. It won't respond to ping, can't ssh in and the terminal doesn't accept keyboard input. It does not have X installed. I then reformatted and installed it from scratch with the same results. There are two hard drives, the first is for the OS and the second is for media. The second has not changed, it is an ext3 formatted drive with one partition. I stopped random services (samba, ushare, transmission-daemon) to see if they were causing the issue, but it still locked up. I did a watch "dmesg|tail" until it locked up, but I didn't see anything. How can I troubleshoot this further? I don't want to downgrade. Machine specs: Dell Dimension 3000 Pentium 4 @3GHz 512M RAM

  • Have to run sudo dhclient eth0 automatically every boot

    I just installed ubuntu 12.04.1 alternative install (for raid 0 on some disks). I Have some problems with the net. I'm at school, we use cable, and it got IPv6.

  • how to make a php crontab silent

    - by BandonRandon
    I set up a crontab in Cpanel to run every min. It's working great but I don't want an e-mail every min. I have a second cron tab that runs every day. I would like the responce of this tab. Is there a way to tell the crontab to be silent or only e-mail on error? I have: * * * * * php /home/public_html/folder/file.php 2>&1 The last bit 2>&1 I added because i thought it would make it silent. From the Cpanel Docs: You can have cron send an email everytime it runs a command. If you do not want an email to be sent for an individual cron job you can redirect the command's output to /dev/null like this: mycommand /dev/null 2&1

  • Testcase runner for parametrized testcases

    - by Razer
    Let me explain my situation. I'm planning a kind of test case runner for doing testcases on external devices, which are microcontroller based. Lets consider the devices: Device 1 Device 2 There exist a lot of test cases which can be run with one of the devices above. For example: Testcase 1 Testcase 2 The main reason that all the testcases can be run with any device is, that the testcases validates some standard and this software should be extensible for future devices. The testcases itself must be runnable with changing parameters. For example Testcase 1 does some Timing Verification the testcase needs as input parameter the datarate: 4800, 9600, 19200. Now hoping you understand the situation, let me explain my design questions. For implementing the test cases I thought about an Attribute based approach, like nunit does it. The more complicated problem is, how to define the parametrized testcases? Like this: Device 1: Testcase 1: datarate: 4800, 9600, 19200 Testcase 2: supply: 1, 2, 3 Device 2: Testcase 1: datarate: 9600, 19200, 38400 Testcase 2: supply: 3, 4, 5 How would you design such a framework? I've done a similar desin in python where I had for every device a XML containing the testcase definitions like: <Testcase="Testcase 1" datarate=4800/> <Testcase="Testcase 1" datarate=9600/> <Testcase="Testcase 1" datarate=19200/>

  • Get the number of tiffs in a multi-tiff with command line ImageMagick?

    - by Anders
    Is there a way to get the number of tiffs in a multi-tiff with a command line utility in ImageMagick? What I want to to is to extract (split) the multi-tiff into single files. However if the tiff only contains one tiff (is not a multi-tiff), I would like to do nothing at all... Also if I use the "%d"-option to name the output files I get the "%d" in the file name if it is only one. ...or is there another way to use ImageMagick to avoid strange filenames when converting?

  • ASP.NET MVC Cookbook &ndash; public review

    - by Andrew Siemer - www.andrewsiemer.com
    I have recently started writing another book.  The topic of this book is ASP.NET MVC.  This book differs from my previous book in that rather than working towards building one project from end to end – this book will demonstrate specific topics from end to end.  It is a recipe book (hence the cookbook name) and will be part of the Packt Publishing cookbook series.  An example recipe in this book might be how to consume JSON, creating a master /details page, jquery modal popups, custom ActionResults, etc.  Basically anything recipe oriented around the topic of ASP.NET MVC might be acceptable.  If you are interested in helping out with the review process you can join the “ASP.NET MVC 2 Cookbook-review” group on Google here: http://groups.google.com/group/aspnet-mvc-2-cookbook-review Currently the suggested TOC for the project is listed.  Also, chapters 1, 2, and most of 8 are posted.  Chapter 5 should be available tonight or tomorrow. In addition to reporting any errors that you might find (much appreciated), I am very interested in hearing about recipes that you want included, expanded, or removed (as being redundant or overly simple).  Any input is appreciated!  Hearing user feedback after the book is complete is a little late in my opinion (unless it is positive feedback of course). Thank you!

  • Using Excel data in Microsoft Publisher

    - by TK
    I have never worked in Microsoft Publisher. To build the presentation we're having to input the same information from a microsoft excel master. For instance- My excel has these columns: Item Title, Item Description, Item Dimensions, Notes, Created Date From there, I'm having the RE-type the information underneath a picture of the item in powerpoint (or publisher) in order to present to the client. So I'm retyping the item name, description, dimensions, etc. I'm also reformatting slides each time I do this. I know there's a way to streamline this process, to build a powerpoint and/or something in publisher that will bring in the data needed based on a merge (or maybe macro), but I haven't been able to figure out how. Any suggestions?

  • Bluetooth mouse Logitech M555b not recognized on a Macbook Pro 8.2

    - by Pierre
    I just bought a Logitech M555b Bluetooth mouse today. My computer (a Macbook Pro 8,2) has a bluetooth connection, and it works perfectly fine on Mac OSX (I set up a new device, click the connect button on the mouse, and voilà, done in 5 seconds). I cannot get it to work on Ubuntu 12.04. When I follow the same steps as on Mac OSX under Ubuntu 12.04, Sometimes I will see the mouse name appearing for 1 second on the screen, and if I'm fast enough to click on "Continue", I will have a message telling me the pairing with my mouse failed. Here are the steps I follow: Turn off Bluetooth on Ubuntu Turn Bluetooth on. Bluetooth icon Set up new device... Turn on the mouse, and press the Connect button. Press "Continue" on the Bluetooth New Device Setup screen I see the mouse name for one second, but then it disappear. Click on PIN options... to select '0000'. ... nothing, Ubuntu won't see anything. In the /var/log/syslog, I have the following information: May 27 23:26:16 Trane bluetoothd[896]: HCI dev 0 down May 27 23:26:16 Trane bluetoothd[896]: Adapter /org/bluez/896/hci0 has been disabled May 27 23:26:58 Trane bluetoothd[896]: HCI dev 0 up May 27 23:26:58 Trane bluetoothd[896]: Adapter /org/bluez/896/hci0 has been enabled May 27 23:26:58 Trane bluetoothd[896]: Inquiry Cancel Failed with status 0x12 May 27 23:28:26 Trane bluetoothd[896]: Refusing input device connect: No such file or directory (2) May 27 23:28:26 Trane bluetoothd[896]: Refusing connection from 00:1F:20:24:15:3D: setup in progress May 27 23:28:26 Trane bluetoothd[896]: Discovery session 0x7f3409ab5b70 with :1.84 activated I tried for an hour, I restarted my computer, re-paired the mouse on Mac OSX, etc. Sometimes when I restart the computer, I have a dialog box showing up saying that the mouse M555b wants to access some resources or something, if I click "Grant", or even if I tick "always grant access", nothing happens... How can I get the Bluetooth to work properly? Help!

  • Sending an email with attachment from server side

    - by SaravananArumugam
    I have to create a word document in a specific format and send it as attachment to some email addresses. I have a preview screen for the report which on approval has to be send in email. This is an ASP.NET MVC 3 application. I am left with a few options here. I am creating the preview using html. I can convert this html into doc and send it, which would be a straight solution. But capturing the Response object's output is being a tough job. I thought of using Mail merge functionality of MS word, where I'll be filling the placeholders of the doc template. But the problem is conceptually, it doesn't appear to be mail merge. I have found someone suggesting to use RTF format and replace the placeholders with database values. Which is the right thing to do? What's the best solution here? Is there any other option than the three listed above?

  • FreeBSD high load loopback interface

    - by user1740915
    I have a problem with a FreeBSD server. There is a FreeBSD 9.0 amd64, two network cards em1 (internet), em0 (local network) configured firewall ipfw, natd, squid (not transparent), the server acts as a gateway for access to the Internet.

  • What is the fastest way to reload history commands begin with certain characters in linux?

    - by gerry
    In Dos we can input the first several characters to filter command history and find proper one rapidly. But how to do the same thing in Linux ? for example when I am testing a local server: cd sudo /etc/init.d/vsftpd start wget ... ls emacs ... sudo /etc/init.d/vsftpd restart sudo /etc/init.d/vsftpd stop ... In Dos you can easily type sudo and switch among the three commands beginning with it using arrow keys. But in Linux, is below command the best we can do ? historty | grep sudo I don't like it, because history can easily become a mess, and it also need mouse action.

  • How to use mencoder to speed up video ?

    - by timday
    There's a webcam streaming WMV video that I can play/record with mplayer/mencoder (Debian Lenny including Debian-multimedia) just fine. I'd like to capture the video such that, when played back, it's faster (so say 100s of real time zooms past in every 1s of video). The "frameskip" filter seems like it ought to do this, but when I try e.g mencoder -o output.avi -ofps 25 -vf framestep=100 -ovc lavc -lavcopts vcodec=mpeg4:... <mms source URL> what I actually get is something which plays for the same length of time as it's allowed to capture for, but which only updates the displayed image every 4 seconds. Is there any way mencoder can be persuaded to do what I want ? (By the way, ideally I'd like to average the frames together to obtain motion-blur instead of just dropping/discarding most of them.).

  • postfix header_checks using regexp proper setup

    - by Philip Rhee
    I just can't seem to figure out why header_checks are not being evaluated. I'm on Ubuntu 12.04, postfix 2.7, dovecote, spamassasin, clamav, amavis. I add following line to /etc/postfix/main.cf : header_checks = regexp:/etc/postfix/header_checks And here is header_checks : /From: .*/ REPLACE From: [email protected] To test out regexp : #postmap -q "From: <werwe>" regexp:/etc/postfix/header_checks which evaluates correctly and give me return output of : REPLACE From: [email protected] However, when I try to send email from commandline or from php webpage, postfix will not replace the From header. I'm stumped.

  • Convert windows media video stream to mp3 audio?

    - by Jared
    I'd like to take a windows media video stream and convert it to mp3 audio. Using mencoder I can convert from windows media video to avi but not directly from windows media to mp3. The following is the command I use to convert to avi, but I'd like to avoid having to do two conversions and converting the avi file to mp3. mencoder mms://wmslive.media.hinet.net/Weblive_Bloomberg_600 -ovc lavc -oac mp3lame -o output.avi Note if there are tools that can do this I will use them, I have access to both Linux and Windows.

  • Python: Check existence of shell command before execution

    - by Gabriel L. Oliveira
    Hi all. I'm trying to find a way to check the existence of a shell command before its execution. For example, I'll execute the command ack-grep. So, I'm trying to do: import subprocess from subprocess import PIPE cmd_grep = subprocess.Popen(["ack-grep", "--no-color", "--max-count=1", "--no-group", "def run_main", "../cgedit/"], stdout=PIPE, stderr=PIPE) Than, if I execute cmd_grep.stderr.read() I receive '' like the output. But I don't have the command ack-grep on my path. So, why Popen is not putting the error message on my .stderr variable? Also, is there a easyer way to do what I'm trying to do?

  • DotNetNuke + PayPal

    - by Nuri Halperin
    A DotNetNuke i'm supporting has had a paypal "buy now" button and other variations with custom fields for a while now. About 2 weeks ago (somewhere in March 2010) they all stopped working. The problem manifested such that once you clicked the "buy now" button, Paypal site would throw a scary error page to the effect of: "Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, [email protected] and inform them of the time the error occurred, and anything you might have done that may have caused the error. More information about this error may be available in the server error log" Once I verified no cheeky content editor changed the page, I went digging for answers. The main source incompatibility of PayPal's simple HTML forms is that DNN includes a form on every page, and nested forms are not really supported. As blogged here and lamented here, the solution I came up with is simply to modify the form enctype to 'application/x-www-form-urlencoded' as illustrated below: 1: <input type="image" border="0" 2: src="https://www.paypal.com/en_US/i/btn/btn_buynowCC_LG.gif" 3: name="submit" 4: alt="PayPal - The safer, easier way to pay online!" 5: onClick="this.form.action='https://www.paypal.com/cgi-bin/webscr'; this.form.enctype='application/x-www-form-urlencoded';this.form.submit();" /> One would think that PayPal would want the masses submitting HTML in all manners of "enctype", but I guess every company has it's quirks. At least my favorite non-profit can now continue and accept payments. Sigh.

  • Apt-get saying "Unable to correct problems, you have held broken packages."

    - by YatharthROCK
    TL;DR: sudo apt-get install ... saying "Unable to correct problems, you have held broken packages." The problem I was trying to get the WebApps feature for PP and QQ following this blog post. I ran the sudo add-apt-repository ppa:webapps/preview command to add the repository, but i got a connection error. Since I know my current ISP gives a shaky connection, I tried again and sure enough, it worked. Then I ran sudo apt-get install unity-webapps-preview, but I realized we had to update apt-get first, so I hit Ctrl + C to stop it. Then I ran sudo apt-get update which worked w/o a fuss, but when I ran sudo apt-get install unity-webapps-preview again later, it showed an error message. Here's the dump: Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: unity-webapps-preview : Depends: xul-ext-unity but it is not going to be installed Depends: xul-ext-websites-integration but it is not going to be installed Depends: xul-ext-webaccounts but it is not going to be installed E: Unable to correct problems, you have held broken packages. I think this might be because of me interrupting the earlier command. It hadn't got a chance to output anything, though — I stopped it pretty fast. What I tried I have tried running a number of commands:- sudo apt-get install --fix-broken sudo apt-get autoclean sudo apt-get autoremove sudo apt-get -f install sudoapt-get install ppa-purgeandsudo ppa-purge ppa:webapps/preview` Even after running sudo apt-get upgrade after every try, none of them worked. Research I tried searching Google, looking at a couple of forums and searching on AU, but to no avail. Help would be appreciated.

  • How do I make the PolicyKit authentication agent window not dissapear when I enter faulty password in Ubuntu 12.04?

    - by Petar
    As far as I remember in previous versions of Ubuntu, whenever authentication was required and when the PolicyKit authentication agent window was presented, it stayed there even after I would enter a faulty password. But now, whenever I make a mistake, the window is closed immediately. I find this behaviour irritating. For instance I use Synaptic rather frequently, and I prefer to start it using Synapse. I press Ctrl+Space to invoke Synapse, then I enter "syn" (s-shows SMplayer, sy- shows System Monitor) and than I press Enter so that Synaptic is invoked. Then I'm presented with the PolicyKit authentication agent window. As my password is rather complicated - using special characters and big letters, it's easy to make a mistake. If I do make a mistake while typing my password, I'm forced to redo all the previous steps. It's annoying as hell, knowing that this is not the way the PolicyKit authentication agent window behaved before. It used to warn me that the password was not correct and than wait for the correct input. I'm not sure if it allowed trying for the correct password indefinitely, or it was limited to 3 retries which is a much saner behaviour than the current one. I'm using Gnome 3, but the same thing happens in Unity too, although the window looks different.

  • MySQL port 3306 blocked in csf yet can still telnet to port 3306 from external host

    - by Neek
    We have a Centos 6 VPS that was recently migrated to a new machine within the same web hosting company. It's running WHM/cPanel and has csf/lfd installed. csf is set up with mostly vanilla config. I'm no iptables expert, csf has not let me down before. If a port isn't in the TCP_IN list, it should be blocked on the firewall by iptables. My problem is that I can telnet to port 3306 from an external host, yet I think iptables ought to be blocking 3306 because of csf's rules. We are now failing a security check because of this open port. (this output is obfuscated to protect the innocent: www.ourhost.com is the host with the firewall problem) [root@nickfenwick log]# telnet www.ourhost.com 3306 Trying 158.255.45.107... Connected to www.ourhost.com. Escape character is '^]'. HHost 'nickfenwick.com' is not allowed to connect to this MySQL serverConnection closed by foreign host. So the connection is established, and MySQL refuses the connection due to its configuration. I need the network connection to be refused at the firewall level, before it reaches MySQL. Using WHM's csf web UI I can see 'Firewall Configuration' includes a fairly sensible TCP_IN line: TCP_IN: 20,21,22,25,53,80,110,143,222,443,465,587,993,995,2077,2078,2082,2083,2086,2087,2095,2096,8080 (lets ignore that I could trim that a little for now, my concern is that 3306 is not listed in that list) When csf is restarted it logs the usual slew of output as it sets up iptables rules, for example what looks like it blocking all traffic and then allowing specific ports like SSH on 22: [cut] DROP all opt -- in * out * 0.0.0.0/0 -> 0.0.0.0/0 [cut] ACCEPT tcp opt -- in !lo out * 0.0.0.0/0 -> 0.0.0.0/0 state NEW tcp dpt:22 [cut] I can see that iptables is running, service iptables status returns a long list of firewall rules. Here is my Chain INPUT section from service iptables status, hopefully that's enough to show how the firewall is configured. Table: filter Chain INPUT (policy DROP) num target prot opt source destination 1 acctboth all -- 0.0.0.0/0 0.0.0.0/0 2 ACCEPT tcp -- 217.112.88.10 0.0.0.0/0 tcp dpt:53 3 ACCEPT udp -- 217.112.88.10 0.0.0.0/0 udp dpt:53 4 ACCEPT tcp -- 217.112.88.10 0.0.0.0/0 tcp spt:53 5 ACCEPT udp -- 217.112.88.10 0.0.0.0/0 udp spt:53 6 ACCEPT tcp -- 8.8.4.4 0.0.0.0/0 tcp dpt:53 7 ACCEPT udp -- 8.8.4.4 0.0.0.0/0 udp dpt:53 8 ACCEPT tcp -- 8.8.4.4 0.0.0.0/0 tcp spt:53 9 ACCEPT udp -- 8.8.4.4 0.0.0.0/0 udp spt:53 10 ACCEPT tcp -- 8.8.8.8 0.0.0.0/0 tcp dpt:53 11 ACCEPT udp -- 8.8.8.8 0.0.0.0/0 udp dpt:53 12 ACCEPT tcp -- 8.8.8.8 0.0.0.0/0 tcp spt:53 13 ACCEPT udp -- 8.8.8.8 0.0.0.0/0 udp spt:53 14 LOCALINPUT all -- 0.0.0.0/0 0.0.0.0/0 15 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 16 INVALID tcp -- 0.0.0.0/0 0.0.0.0/0 17 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED 18 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:20 19 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:21 20 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:22 21 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:25 22 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:53 23 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:80 24 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:110 25 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:143 26 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:222 27 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:443 28 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:465 29 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:587 30 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:993 31 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:995 32 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:2077 33 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:2078 34 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:2082 35 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:2083 36 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:2086 37 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:2087 38 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:2095 39 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:2096 40 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:8080 41 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 state NEW udp dpt:20 42 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 state NEW udp dpt:21 43 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 state NEW udp dpt:53 44 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 state NEW udp dpt:222 45 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 state NEW udp dpt:8080 46 ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 icmp type 8 47 ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 icmp type 0 48 ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 icmp type 11 49 ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 icmp type 3 50 LOGDROPIN all -- 0.0.0.0/0 0.0.0.0/0 What's the next thing to check?

  • Groovy Debugging

    - by Vijay Allen Raj
    Groovy Debugging - An Overview:ADF BC developers may express snippets of business logic (like the following) as embedded groovy expressions: default / calculated attribute valuesvalidation rules / conditionserror message tokensLOV input values (VO) This approach has the advantages that: Groovy has a compact, EL-like syntax for expressing simple logicADF has extended this syntax to provide useful built-insembedded Groovy expressions are customizableGroovy debugging support helps improve maintainability of business logic expressed in Groovy.Following is an example how groovy debugging works.Example:This example shows how a script expression validator can be created and the groovy script debugged. It shows Step over, breakpoint functionalities as well as syntax coloring.Let us create a ADFBC application based on Emp and Dept tables, and add a script expression validator based on the script:  if (Sal >= 5000){ //If EmpSal is greater than a property value set on the custom //properties on the root AM //raise a custom exception else raise a custom warning if (Sal >= source.DBTransaction.rootApplicationModule.propertiesMap.salHigh) { adf.error.raise("ExcGreaterThanApplicationLimit"); } else { adf.error.warn("WarnGreaterThan5000"); } } else if (EmpSal <= 1000) { adf.error.raise("ExcTooLow"); }return true;In the Emp.xml Flat editor, place breakpoints at various locations as shown below:Right click the appmodule and click Debug. Enter a value greater than 5000 and click next. You can see the debugging work as shown below:  The code can be also be stepped over and debugged.
