Form Property 'Long' Is Interpreted by Java Class as 'Intege

I specified a "long" type for an activiti:formProperty in the BPMN20.xml (actually in Designer) for variables "loanAmount" and "income". Then in a Java class I tried to do execution.getVariable("varName") casting the return value to both a Long and a String. Each time I had a "ClassCastException:

Which version of Activiti are you using? How did you test this?
With a unit test?
If so, please post the full project so I can reproduce it.

Best regards,

I acutally tested this with a unit test, changed to code to work in the unit test, deployed that via Explorer and tested in Explorer. I had different results in both tests. The unit test gave the results shown already had a class cast exception trying to cast an Integer to a String. Explorer gave a class cast exception saying that I could not cast a Long to an Integer.

I am still working on the project and it is a little unstable right now. As soon as I get it stable again I will post it for you.

Thank you.

The process still has some problems later than the part that shows the problem I described above, so here is a copy. I am not sure what you mean by the full project. Here is the bpmn20.xml and the classes that I use. When I try to attach .java files, the forum form give me a message "The extensin java is not allowed" so I hope you get everything. If not, I can get the code to you other ways.

Thank you.

The descrepancy I described is one I caused in my "tester" class. When I put values into the process variables sent to the startProcessInstanceByKey() method, I specified Interger for the values. So, naturally the process would interpret the fields as Integer rather than Long.

Thank you for your quick replies to my posts and patience while I am still learning how to work with the engine.
