@DataModel problem

[jump]

I have a simple bean with DataModel and DataModelSelection

@Stateful
@Name("toolbar")
@Scope(ScopeType.SESSION)
public class ToolbarImpl implements Toolbar {

 ...................

 @DataModel
 public List<ProcessDefinition> getProcessDefinitions() {
 return processDefinitions;
 }

 @DataModelSelection("processDefinitions")
 private ProcessDefinition selectedProcess = null;

 public String createProcess() {

 System.out.println(selectedProcess + " process started");
 return null;
 }

}

And a simple page

<rich:dataTable value="#{processDefinitions}" var="process">
 <rich:column>
 <h:commandLink value="#{process.description}" action="#{toolbar.createProcess}" style="font-size:14px">
 <h:graphicImage value="#{process.processIcon}" style="width:42px;height:42px;border:0" align="middle"/>
 </h:commandLink>
 </rich:column>
 </rich:dataTable>

and a simple exception

Caused by java.lang.IllegalArgumentException with message: "Could not invoke method by reflection: ToolbarImpl.getProcessDefinitions() with parameters: (java.util.ArrayList) on: virtprofstud.ToolbarImpl"

In this way it works

 @DataModel
 private List<ProcessDefinition> processDefinitions;
 @DataModelSelection("processDefinitions")
 private ProcessDefinition selectedProcess = null;

Is getProcessDefinitions() defined in your ToolBar interface?

[jump]

yes. It works fine with seam 1.2.1GA
