YAWL Editor Bug (Problem with Decompositons, registered YAWL Services)

Hey,

I have some problems / found a Bug with the YAWL Editor Version 2.1Beta.

I tried to create a decomposition, but I could not chose any registered YAWL-Service. The following NoClassDefFoundError error occured:

My solution is to open the YAWLEditor2.1Beta.jar with 7zip, browing to the YAWLEditor2.1beta.jar\org\yawlfoundation\yawl\ directory and adding the authentication directory and its files from YAWL_INSTALLATION_PATH\engine\apache-tomcat-6.0.18\webapps\yawl\WEB-INF\classes\org\yawlfoundation\yawl\.

There is another problem, the YAWL Editor does not save the login information in the "Resource Service Connection" Dialog.

Hope, I could help.

Cheers, Robert
