Description Joerg Reichert CLA 2010-06-03 03:09:13 EDT 
Build Identifier: Eclipse 3.6 I20100527-1700, MWE 2 runtime SDK 1.0.0.v201006010340	

Hello Sebastian,

I wrote you about this issue a month ago but I did not fill in a bug yet. As the fix is still not contained in the current milestone I am doing now.

I have complained that this construct in MWE has no equivalence in MWE2 yet:

<if cond="${cleanTargetDir}">
  <component class="org.eclipse.emf.mwe.utils.DirectoryCleaner"  
       directory="${targetDir}"/>
</if> 

Your answer was: The IfComponent still exists, but unfortunately it does not implement the interface expected by the new implementation yet. There is currently only a compatiblity to AbstractWorkflowComponent but not to 
CompositeComponent. When realized the syntax would be

if = {
   cond = "${..}"
   component = DirectoryCleaner {
   }
} 

Reproducible: Always

This has been fixed since RC1. 
org.eclipse.emf.mwe.core.container.CompositeComponent implements org.eclipse.emf.mwe2.runtime.workflow.IWorkflowComponent

Do you have any trouble using the if component?

My mistake, I used the wrong syntax, the right syntax is:

component = org.eclipse.emf.mwe.core.container.IfComponent {
  cond = "${cleanTargetDir}"
  component = DirectoryCleaner{
     directory = targetDir
  }
}
