Using Vaadin Eclipse-Plugin for extending the activiti-explorer

[b_schnarr]

Hello at all,

I need to extend the activiti explorer that it fits to our requirements. Therefore, I installed the Vaadin Plugin for eclipse. After that,  I checked out the wholeactiviti project from https://github.com/Activiti/Activiti with the import git project wizard in eclipse. After that, I converted the whole project into a maven project (right click on the project, configure, convert to maven project)

My question is: how can I use the vaadin visual editor to graphically edit the activiti explorer. When I open a java class in the activiti-explorer package, I do not succeed in opening the vaadin visual editor.
Did I miss something?

Best regards and thanks for your help
Ben

When I try to open a java-file with the vaadin visual editor, I get the following message:

Could not open design view:

caused by
Activiti does not exist

with the following stacktrace:

Has anyone an idea?

Nope, sorry, I never used the Eclipse plugin for Vaadin … I don't really like these builders for UI's.
