Can exclusive gateway expression be based on process dataObject value?

Question asked by aabb_activiti on Oct 13, 2017

Iam using eclipse plugin to model my workflow and java api engine to interact with .

I have dataObject that i defined in my workflow : timer_off (String)

however , when i try to access this variable in exc. gateway expression, logger returns : unknown property timer_off used in ....

this is how i defined expression in xml : conditionExpression.....<[!CDATA[${timer_off==null}]]>

So my questions are :

-Are process DataObjects accessible in conditionalExpressions?

-What is the right way to write it?

 

Thanks
