Designer loading problem in drools-guvnor

[tomcheng76]

I use guvnor to upload jbpm-examples's Evaluation2.bpmn
but i cannot open it in drools-guvnor via Packages => defaultPackage => Processes
It stops at "Please wait while loading..."

prototype-1.5.1.js:449

Uncaught TypeError: Cannot call method 'split' of undefined

Tried designer-1.0.0.053-jboss.war too, it is the same

Anyone knows how to solve this problem? idea, comment and solutions are welcomed.

Thanks a lot

[tsurdilovic]

I am not able to reproduce the issue. Evaluations2.bpmn round-trips fine in the oryx web designer (1.0.0.053 and pretty sure would in 052 as well). Show you entire error in server logs. Most likely is that you are using an older Guvnor version. If you use 1.0.0.053 you need to use Guvnor from master currently (build it yourself).

Thanks.

Do you mean this log ?

Sure, that's your server log and there are no exceptions while parsing the bpmn2 so is the diagram still not being displayed? What are the exact designer and guvnor versions used so I can try to reproduce? Your earlier post indicates that you may be running into some front-end issues...if you are on firefox do you see any errors in the error console?

[tomcheng76]

Thanks for your reply

Firefox console shows this

stencilsets.js (line 83)

namespace is undefined

[Break On This Error] var splitted = namespace.split("#", 1);

If i click About in guvnor, it shows Version 5.2.0.Final

This is my step of installation, i hope i didn't miss anything
1. extract jbpm-5.1.0.Final-installer-full.zip
2. ant install.demo
3. ant start.demo
4. ant stop.demo

5. change build.properties

designer.version=1.0.0.053-jboss

designer.url=http://sourceforge.net/projects/jbpm/files/designer/designer-1.0.0.053

6. manually download designer-1.0.0.053-jboss.war and put it to lib

7. make a copy of the designer-1.0.0.053-jboss.war in jboss-5.1.0.GA\server\default\deploy and rename to designer.war
8. ant start.demo

I don't want to reinstall jbpm because it doesn't help learning.

I am having this problem too
http://community.jboss.org/thread/169336?tstart=0
and reinstall will solve this problem but it happens again....

[tomcheng76]

I give up 053 and focus on 052, Here is the full step procedure to reproduce the problem (re-installation)

Re-download all packages if there isn't any problem (skip copying)

1. ant stop.demo
2. delete test.h2.db in C:\Users\username
3. re-extract jbpm-5.1.0.Final-installer-full.zip to a new directory
4. change build.properties

jBPM.birt.download=true

5. Copy the following file to lib
birt-runtime-2_3_2_2.zip, eclipse-java-helios-SR2-win32.zip, GEF-SDK-3.6.2.zip, jboss-5.1.0.GA.zip

6. Copy the h2.jar to db\driver
7. ant install.demo

8. ant start.demo

9. open Guvnor and New BPMN2 Process inside

I tried chrome and firefox, cannot open the process...

[tsurdilovic]

I just tested with jbpm 5.1 installer using all defaults (which includes 1.0.0.052 designer). Ran ant install.demo and ant start.demo then uploaded both Evaluation.bpmn and Evaluation2.bpmn from the jbpm-examples module. I am able to view and save the processes without any issues..and am also able to create new processes.

Tried debugging the javascript error you said you were getting in stencilsets.js. The exception you are getting really should not happen..this is really weird because I am not sure how to reproduce the problem.

Thanks.

[tomcheng76]

Thanks for your effort.

More debugging info
stencilType = "BPMNDiagram"
this.id = "Definition"

ORYX.Core.StencilSet._StencilSetNSByEditorInstance = Object { Definition=[1]}

ORYX.Core.StencilSet._StencilSetNSByEditorInstance[editorId] = [undefined]

i really don't understand why it is not working...even after re-installnation...

my java is "1.6.0_25"...

Not sure why the json file is not complete though, hope it is the root of the problem

jbpm-installer\jboss-5.1.0.GA\server\default\tmp\3j001-1lfrgo-gqdfdf7r-1-gqdffoc5-9v\designer.war\stencilsets/bpmn2.0jbpm/bpmn2.0jbpm.json

http://pastebin.com/PstwEHaV

[tsurdilovic]

I have not seen this before. There is no reason the bpmn2.0jbpm.json file should abruptly stop like in your pasted code. When you open the designer, this file get's generate from a default template and workitem configurations present in guvnor (which I assume you have none).

Can you try opening the designer in browser outside of guvnor (http://localhost:8080/designer/editor?profile=jbpm&uuid=12345&pp=) and hook up a javascript debugger to see what you get?

[tomcheng76]

Same error as above.

Though this.id changed to 12345.

I tried replace the bpmn2.0jbpm.json file with the original one in the war, but it is re-generated with a broken json once i open the designer...

what is the mechanism behind the re-generation? can i suspend it ?

[tsurdilovic]

Sorry I have not seen this error reported before and have not had it happem during tests. Wonder if it's specific to Windows? The template file used to generate the bpmn2.0jbpm.json is

/stencilsets/bpmn2.0jbpm/stencildata/bpmn2.0jbpm.orig

You may want to try to replace that one with the data of the original bpmn2.0jbpm.json and see if that helps, but again I'm not sure why the generation fails (you cannot turn it off right now btw.). What is the Guvnor version used?

[tomcheng76]

I checked the orig file and it is correct with filesize 166KB

Generated json is 14KB

Of coz replacing file is not working

I just added the JBOSS AS to eclipse, the error log is this

12:25:54,770 INFO  [STDOUT] (null: -1, -1): Premature end of file.

Is there a way to adjust the log level or setting a breakpoint so that i can further investigate the source of the problem?
Which file should i set the breakpt to ?

My Guvnor version is 5.2.0.Final. thanks

[tsurdilovic]

The difference in the file size is not really an issue. The generated file size can be smaller or much bigger depending on how many custom workitem definitions are found in your guvnor repository in the package you create your process in. In case you do not have any workitem definitions, the file size of the created json is actually smaller as the .orig ..this is fine.

As far as log levels, check out this post with one answer -> http://community.jboss.org/thread/150803.

Hope this helps.

Hi Tihomir,

I also got the same problem when deploying to Solaris server. When I deployed under my PC, it is fine.

I compared the console logs between solaris server and my localPC  and found that:

HTTP Get to http://167.0.0.45:8080/designer/stencilset/bpmn2.0jbpm acturally returns nothing which cause:

namespace is undefined

var splitted = namespace.split("#", 1);

Then I check the doGet() method of EditorHandler.java and found that it used the fixed path /designer/XXX. It seems that addScript() didnt find the javascipt files

I suspect that the path cannot be located in my deployment although I didnt change the folder structure in designer.war.

Tommy, do you have any other findings?

[tsurdilovic]

Are you by chance deploying web designer as an exploded war in dev and as a .war file in production? I am suspecting that in EditorServlet.java:

[code]

private static String readEnvFiles(ServletContext context) throws IOException {

        FileInputStream core_scripts = new FileInputStream(

                context.getRealPath("/js/js_files.json"));

....

[/code]

context.getRealPath() is returning null for some reason...could you check to make sure?

Try to deploy as an exploded war in prod and let me know if that fixes the problem.

Thanks.
