I have a custom palette with custom icons and I try to add a custom shape(class) to the diagram but I get a forbidden symbol and then the following exception:

What am I missing?

Hi,

There is a missing element type, that's why there is a NPE

In any case it shouldn't throw an NPE. I opened a Bug 514289

I checked your files but didn't see any obvious issues.

Can you share a full plugin?

Regards,
Benoît

hi,

I check quickly your files. You forgot to remove comments brace on the declaration of the semantic element type model.
I see that you use matcher. I don't don't how exactly this work but if you goal is to create a stereotyped element, try to use instead stereotype advice helper. I will send you an example as soon as possible if need.

hth.

you can add stereotype with:

<adviceBindingsConfigurations xsi:type="applystereotypeadvice:ApplyStereotypeAdviceConfiguration" identifier="your.id" target="//@elementTypeConfigurations.0">
<stereotypesToApply stereotypeQualifiedName="SysML::Blocks::Block">
<requiredProfiles>SysML</requiredProfiles>
</stereotypesToApply>
</adviceBindingsConfigurations>

I could not find the comments brace you are referring to.

This exception happens when I click on the palette and move the cursor to the diagram view. is that a missing element exception or something related to the Diagram?

I checked your sources.

Id of elementTypeSet (in your models) should be unique: both are using edu.utd.cse.cerbac.cerbac.elementTypes

Changing one in edu.utd.cse.cerbac.cerbacdi.elementTypes (and un-comment the registration point) allows me to create "Positive Obligation"

Hi Benoit,
Can you send me the files you changed to get it to work? I made the changes but still having the issue.

Thanks.

ok Benoit, I got it to work. I restarted eclipse after the Id changes and I was able to add a few stereotypes. I also noticed that when there is a problem with the typesconfiguration, the exception previous exception is raised.

Thanks for your help.

Hi,
I cant get the associations to work. Do you know what the problem could be?

Hi,

For association you have to use kind="ConnectionTool" in the palette.

If your sources are open, it would help a lot (avoid to re quest it for each question) if you can share them on a repository (Github, Bitbucket, Gitlab or whatever you like)

Hi Benoit,

I have added the source to GitHub repository
https://github.com/tonero101/cerbac.git

I resolved the association problem with your answer, Thanks.
Right now I am having a DSML validation and public profile. I created a topic with the issue.
Thanks
