Hi guys,
my "problem" is:
I am using *jBPM 4.3* and i have a java node:
<java class="it.sample.Action" g="67,348,92,52"
method="getOutput" name="Action" var="output">
<arg>
<object expr="#{inputObj}">
<property name="keyword"><string value="CLIENT
CODE"/></property>
<property name="location"><string
value="0,0,2539,700"/></property>
<property name="fieldRegExp"><string
value="([0-9][\\s]*?){6}"/></property>
</object>
</arg>
<transition g="-68,-18" name="to evaluate result"
to="evaluate result"/>
<transition name="to error" to="error"
g="-42,-18"></transition>
</java>
and my class is:
public class Action{
public MyClass getOutput(InputObj obj){
try {
MyClass output = obj.getOutput();
return output;
} catch (Exception e) {
e.printStackTrace();
// TODO: REDIRECT TO ERROR TRANSITION
}
}
}
and it works, but I need to take transition "to error" (the one I have defined
in java node) when I catch an Exception and I don't know how to do that.
I've tried to use a <custom> node instead implementing ExternalActivityBehaviour
but i don't know how to pass my argument to execute method. I can't set the
arguments as variables in previous nodes, because my chiefs pretend to perform the
operation in one step.
Any suggestion to solve this?
Thanks in advance
