Hi,

I have this problem: some process definition using decisions worked well on JBPM 3.1.4, but when i tried upgrading to 3.2GA, it always chose the default transition (no decision was correctly evaluated).
After some tries, I've seen that the conditions simply do not work in that syntax - using the 'expression' as ATTRIBUTE of the condition tag - but works in the alternate one: using expression as child element.

Is this normal in 3.2 ?

from the userguide (18.4.29. condition):
"{content} For backwards compatibility, the condition can also be entered with the 'expression' attribute, but that attribute is deprecated since 3.2"
if it's still allowed (even deprecated), i was expecting it to still work, somehow...

this junit test shows this:

import junit.framework.TestCase;
import org.jbpm.graph.def.ProcessDefinition;
import org.jbpm.graph.exe.ProcessInstance;

/**
 * JUnit test of JBPM to check issues regarding the sintax of conditional transitions.<br>
 * In 3.2 it seems that using the 'expression' ATTRIBUTE of the <condition> tag does not
 * work! (but only the alternative, where the expression is passed as a child element of the tag!)
