activiti:formProperty value not getting set

[darshan_hardas]

We are having a BPMN XML file to where we need to share the properties from startEvent in one of exclusive gateway of a user task. We tried setting the default, value and also the variable. But still it is not working and always the value is empty.

The xml is pretty much similiar to the above code.
Please guide us.

Thanks in advance.

Hmm that should do it.

Are you submitting your variables correctly? How does this call into the api looks like?

Is the database table for variables ACT_RU_VARIABLE populated with the values?

[darshan_hardas]

Thanks for the reply!!!

We are getting the value of the submitted variables in the exclusiveGateway i.e. checkleaveReason gets the value of "leaveReason".
But when we use the variables in the userTask, it does shows up and the value is always null
<code>
<activiti:formProperty id="leaveReason" name="Motivation" type="string" >${leaveReason}</activiti:formProperty>
</code>

We also tried
<code>
<activiti:formProperty id="leaveReason1" name="Motivation" type="string" >${leaveReason}</activiti:formProperty>
<activiti:formProperty id="leaveReason2" name="Motivation" type="string" value="${leaveReason}" />
<activiti:formProperty id="leaveReason2" name="Motivation" type="string" variable=${leaveReason} />
</code>

But always the value is coming as null or empty.

Hello,

Good description how form properties work is in the jUnite tests (e.g. org.activiti.engine.test.api.form.FormServiceTest#testFormPropertyHandling). I would say >${leaveReason}</ is not needed.
Just use the simple


<activiti:formProperty id="leaveReason" name="leave Reason" type="string" />

in the user task. (it should work)

Martin

We want to assign the value of "leaveReason" variable of the startEvent in the another userTask. Below is the code.
<code>
<activiti:formProperty id="leaveReason1" name="Motivation" type="string" >${leaveReason}</activiti:formProperty>
</code>

Here, the value of leaveReason1 is empty.

Hi,

try to use

<activiti:formProperty id="leaveReason1" name="Motivation" type="string"  value="${leaveReason}"></activiti:formProperty>
