binary form: GetRenderedStartFormCmd vs GetStartForm w/ rest

[markjans]

Hi,

I'd like to load a binary actionscript module as a process definition form via the activiti-rest webapp, however the exception below is thrown by the juel engine during processing.

I can see the GetRenderedStartFormCmd vs GetStartForm in the codebase, but is there a way to cause the restful webapp to load the form unrendered?

Many thanks,
Mark

Currently, there is no way of getting an unrendered form from REST.

There is an issue that describes this functionality: http://jira.codehaus.org/browse/ACT-269

Thanks for the reply Frederik.

So would the recommended solution be to return a 'form' with the path to the deployment artifact ?

Mark,

Indeed, use the formResourceKey on the Task (or startFormResourceKey on ProcessDefinition) as resource-name, and use:

GET /deployment/{deploymentId}/resource/{formResourceKey}
This is a workaround, so keep this in mind.
