Applying a extension to Activiti Designer

Hi,I'm trying to change and extend the palette of activiti designer. I have followed the user guide, used the examples and successfully created the jar file with maven install. Maven doesn't report any errors and the jar file includes the classes of the example. But if I put this jar file to the Act

Christian,

the palette doesn't change immediately, you have to re-open diagrams. If it still doesn't work, take a look at the log file in eclipse's workspace, there's probably a stacktrace in there. I know it's not the most user-friendly way to spot errors and I'm considering a different approach that validates the extension and reports any problems it finds. For now though, the log file is the place to look. There's probably some reason it can't load your extension.

The version mismatch could also be a problem. I'll ask Tijs to upload the 5.7 compatible version.

I see one failure with stacktrace in the log file if I open a .activiti file, but it triggers with and without the designer extension jar in the user library.

The version mismatch could also be a problem. I'll ask Tijs to upload the 5.7 compatible version.

That would be great.

That stacktrace is a "normal" stacktrace and I'm sure it has nothing to do with your extension. I've emailed Tijs to add the integration lib to Nexus.

I've uploaded 5.7 to the Maven repository.

Hi,

I've got the same problem with 5.8 version. I've followed the guide, but no new node is displayed in palette.
Where might be the problem?

Thanks in advance!
