Crash when accessing all tasks list

[jacentino]

Hi,

The problem occurs for grails 2.1.0 and activiti plugin 5.9 To reproduce it:

1. Choose any user on the start page
2. Choose the vacation request controller
3. Create one vacation request
4. Go to "All Tasks" list

The error page reports java.lang.IllegalArgumentException with the "Dynamic method get<Artefact>Class(artefactName) requires a single String parameter" message.

The stacktrace is: 2013-02-10 22:49:32,602 [http-bio-8080-exec-7] ERROR StackTrace - Full Stack Trace: org.codehaus.groovy.grails.web.pages.exceptions.GroovyPagesException: Error processing

Thanks for your interest to the plugin and creating the issue report. I didn't have the problem you faced while I built the sample app few months ago, can you tried http://grails-activiti-plugin.googlecode.com/files/activiti59-sample.zip and let's me know your status?
