[jboss-user] [jBPM] - Cannot retrieve Boolean/Integer variable from generated process start form

Aurélien Pelletier [https://community.jboss.org/people/apelletier] created the discussion "Cannot retrieve Boolean/Integer variable from generated process start form" To view the discussion, visit: https://community.jboss.org/message/801498#801498 -------------------------------------------------------------- Hello, I'm evaluating jbpm 5.4 and I'm trying to implement a very simple workflow: I want to start the process with an amount(Integer) variable then if amount>X do task A if amount<=  do task B. nothing fancy and I've figured how to implement it. But there is a bug: With the jbpm designer I define an amount:Integer in the variable definition of the process, then I generate the form, build the package... I use the generate form to launch the process: http://localhost:8080/gwt-console-server/rs/form/process/defaultPackage.T... http://localhost:8080/gwt-console-server/rs/form/process/defaultPackage.T... It works, but if I check the instance data in the jbpm console the amount variable is not an Integer but a String. Then if I try to use like an Integer I get a class cast Exception. This issue looks a lot like this one: https://bugzilla.redhat.com/show_bug.cgi?id=854965 Cannot retrieve Boolean variable from Human Task when using generated task form Which is fixed in 5.4... The workaround I'm using is to start the process with a user task where I submit again the amount. In this case the amount object is an Integer and it works. It looks like the conversion from String to Boolean/Integer/... is called for task generate form (/gwt-console-server/rs/form/task/{id}/render) but not for process start generated form (/gwt-console-server/rs/form/process/{id}/render) I've tried to define a dataoutput and dataMappingAssociation in the start event. But when I type the amount variable with amount:Integer the event start extra properties the type defition (:Integer) is removed when I save the file... Am I doing anything wrong ?
