Is it possible to configure the process so when a call activity has out mappings
and the sub-process does not create the variables, the out mapping does not create null variables in the parent process?
Hi @StephenOTT,
in case of using the target
attribute of the camunda:out
element, a variable is always created even if the source
attribute has a null value. Is variables="all"
what you are looking for? This attribute passes all subprocess variables to the parent process.
...
<camunda:out variables="all" />
...
Does this answer your question?
Cheers,
Tassilo
In this case I do not want to return all variables. But I only want to return the variable if it has a value/if it was created in the sub-process
As far as I know this is not possible just with the out mapping feature.
Feel free to create a feature request for that in our jira.
