Exception when trying to evaluate constraint

[rogerparkinson]

My process has a process variable called fundsOkay defined as a boolean.

I have a gateway that branches one way of fundsOkay is true and the other way if it is false.

That's what I hoped would happen, but when I run this process under workbench (kie-wb-6.1.0.Final-wildfly) I get the attached stack trace.

At launch it prompts for all my process variables and I enter false into fundsOkay, but it looks like when it comes to evaluate it in the gateway fundOkay is a String and it gives a ClassCastException

I've tried several expressions in the gateway scripts, but they are currently set to:

return  !Boolean.valueOf(fundsOkay).booleanValue();

and

return  Boolean.valueOf(fundsOkay).booleanValue();

earlier they were using return  KieFunctions.isTrue(fundsOkay); and return  KieFunctions.isFalse(fundsOkay); with the same error result.

What am I doing wrong here?

Thanks for any help

you should generate forms with form modeler (graphical form editor) that will properly handle type conversion of you. For example for boolean type you will see check box on your form instead of text box.

Thanks. I hadn't made the initial form and had left it to the default generated. Now that I have it works fine, well I think it does.

I have another issue that prevents me from trying it just now.
