Hello,

I have a problem with the postMessage invocation of the method completeTask.

I have a ZK web application that invokes the REST API of JBPM to get the task list from JBPM. I would to integrate the showForm and the task operations provided by the jbpm-forms-rest-integration.js.

After initial problems of Cross Origin solved adding the header in standalone configuration of Wildfly now  I have a problem to call the postMessage method for the iframe containing the form.

In my ZK page I include a JSP that invokes the showTask form and has a button that calls the completeTask method.

The method is invoked but without effects or exceptions. I've seen that the call of contextWindow returns an object and not a window. I believe that this is the problem, how can i solve it?

Or what is the solution for my problem?

Thank you
