org.eclipse.swt.SWTError: No more handles #27

[bourboule]

Version of Archi, Operating System

Archi 4.4.0
Build 201904031131
Plugin org.archicontribs.form_v1.9.1.jar https://github.com/archi-contribs/form-plugin/blob/master/org.archicontribs.form_v1.9.1.jar

Expected Behaviour

When using Form plugin, the form windows should be setup with element properties and usable through mouse and keyboard.

Actual Behaviour

This issue is already explained in form plugin issues. Herve ask me to open an Archi issue too: archi-contribs/form-plugin#27

handle.archimate.txt
handle.conf.txt

After few seconds of form building process, I can't no more use Archi.
The form windows still displayed and can't be closed. Icon "Please wait, we are creating the form..." still displayed inside the window.
I have to kill the process Archi.exe.

Here is the error log:

Here is the end of plugin log file:

I think I reached some limits (org.eclipse.swt.SWTError: No more handles).

I have a work around: split this view in many views with less elements inside, but if I could avoid, it'll be great. This view has a special name which is used by a script to extract properties and node from XML files.

I have tested without solving the issue:

• to increase max memorysize in archi.ini to 2GB, 4GB
• use 32 or 64 bit version
• remove specialization and modelrepository plugins

Steps to Reproduce the Behaviour

1. Install form plugin: org.archicontribs.form_v1.9.1.jar
2. Configure form with parameter file handle.conf (in attachment)
3. Open model file handle.archimate (in attachment)
4. Click on contextual menu Test Handle

Actually, Herve said this:

You may as well open a case in Archi forum to get help from the whole Archi comunity:(https://forum.archimatetool.com/index.php)

So I'm going to close this issue here and please use the original issue archi-contribs/form-plugin#27

Ok. Sorry for this misunderstanding.

No problem! :-)
