Any way currently to parse JSON string within expression?

[tstephen]

Specifically I want to use the multi-instance functionality to do something for each item in a JSON array. I have the JSON array in a process variable 'myJSONList' and would like to specify the multi-instance collection as ${myJSONList} having each object in the array be set as the element variable.

Is there a way to do something like this now? And if not, how would I go about adding it? I'm thinking of adding a new ElResolver to the org.activiti.engine.impl.el.ExpressionManager, is that on the right lines?

Cheers,
Tim

We don't have support for json in the expressions. But it certainly would be cool!.
Yes, you are on the right path. The VariableScopeELResolver already could provide some insight there.

If you're stuck somewhere, let us know and we can lend a hand!

Hi JOram Barrez‌,

I would need to parse a JSON array within expression in order to use multi-instance feature. Is this supported now?

Thanks,
