[jboss-dev-forums] [Design of JBoss jBPM] - conditional transitions in 3.2GA - not working when using ex
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!)
