HTTP 500 error when executing custom value provider

  Hello Olga,

I've written my own value provider in JavaScript however I'm encountering the following error when I try and trigger the provider:

A quick google suggested that this could be because the Enable Process Attachment Scripts setting was false, and indeed it was, however after enabling it and restarting the server I'm still seeing the same error.

I've tried this on two different servers and am seeing the same results on each, so I'm likely doing something fundamentally wrong; any suggestions?

Edit: I've done some more testing and this error only seems to appear when the attribute I'm calculating has a dependency on another attribute. A standalone script that's just calculating a single value seems to work without issue.

I've had exactly the same problem, & after pulling out lots of hair, I think I've figured it out. I had a single case working OK, then it broke when I added a second custom value provider & script. I had copied the existing script, changed it as needed, then attached it to the new provider. After hitting save & testing the UI again, I noticed it was calling the original script I had just duplicated.

Something internal seems to remember & reference the prior Class name, and even if you upload new/different scripts with different names, they will be ignored and the original script will be pointed at. I then started getting the HTTP 500 errors after purging the original script in my effort to clean/fix things.

My resolution was to upload a completely new script with a new unique class name. Everything seems to work OK then. I think even changing the prior script to a different class name does not work correctly.

I have no clue if this is a bug or working as intended, but if having duplicate class names is such a problem, it would be nice to get some warning when you first attempt the save/upload. I've lost 2 days trying to figure this out... :(

Edit: After straightening out the class names earlier, I found later that I had also copied in an incorrect script (I copied a DefaultValueProvider script into a ValueProvider script). This also resulted in an HTTP 500 when the calling script failed to find a getValue method (you can see this in firebug). I now have multiple custom attributes, all dependent on other custom values, all calculating OK via multiple scripts. Hurray :)

I tried what you suggested and renamed & re-uploaded the JS class but unfortunately I still have the same issue.

I'm leaning towards this being something to do with the configuration of the project I'm using as I tried uploading to a newly created project based on the Scrum template and it worked with no issues.

Hi Jared,

I read your thread because I'm currently facing the same problems with a custom value provider. I also tried a lot of things like deleting the script, deleting attributes, create a new script, and so on but nothing really works. Did you find any way to solve the problem or did you stop looking for a solution?

Is there anybody out in the community with the same problems and found the reason for it?

We are still using RTC 3.0.1.2 on Windows 2008 R2 with MS SQL Server 2008, but I also recognized the problem on RedHat Linux so it's a platform independent issue.

I'm also with Jared that the issue must be a problem within the project area because the scripting works without any problems in other project areas on the same server.

Regards
Matthias

Hello,
the error states : 

java.lang.IllegalArgumentException: Resource does not exist: com.mycompany.workitem.provider.RiskScoreProvider.js

which basically means that the referenced JavaScript is not found.

This is common when either:
- JavaScript processing is not enabled at server level (which is the default)
- your project area - and especially the custom value provider you declared - is not in sync with what is deployed on the server.

--> reloading the file to the server should fix the issue

Thanks

Hello Matthias,
well - possibly you may want to use Firebug and/or IE embedded developer tools to investigate this error further.

Without the PA source and associated Javascript, there is not much I could do here.
You may want to open a public work item or a PMR - https://jazz.net/help/support/

Let me know.
Thanks

We have finally fixed the issue.

There were a couple of scripts attached to the project area
Matthias removed all the scripts and upload the script once again
that solved the problem

Hi Eric,

I have similar problem... After plugin deployment & server reboot, web continue same behavior as without plugin, but in ccm.log I found that plugin alive & try run...

**The JavaScript processing is enabled on the server.

Hi Olga,

in your extension plugin for contributing the action, please make sure that the dojo class, extension ID, and extension structure matches so it can be found.

For example, I see in the error log your file is: rb.jazz.workitem.toolbar.actions.ui.LinkedDefectEditorToolbarAction.js

So that would be ( taking https://jazz.net/library/article/782/ as guide):

• "rb.jazz.workitem.toolbar.actions.ui.LinkedDefectEditorToolbarAction" as the declared dojo class
• rb.jazz.workitem.toolbar.actions your extension plugin ID
• and the dojo class stored in "ui" folder
  

Regards,

Jorge.

Hi Olga,

as discussed, you have to align the action you declare in your extension, the plugin ID and dojo class, so it can be found. Trying to summarize it: the action declaration should declare a full naming that can be resolved from plugin ID completed with folders under resources and class declaration. For example:
 - action="net.jazz.test.workitem.web.editorToolbarAction"
 - in a plugin with ID "net.jazz.test.workitem.web",
 - it will look for a dojo class "editorToolbarAction" in a file "editorToolbarAction.js" which is located within project "resources" folder.

Regards,

Jorge
