Problem adding Variables when starting with submitStartFormData

[prace]

Hi,

we want to start a Process with Form Parameters for the startEvent. For later steps in the Workflow we need to add additional variables.
I know that all Form Variables will become Workflow variables so I could just add them to the submitStartFormData call in the Map.

Problem for us is, that the signature of the Map supplied to startProcessInstanceByKey is Map<String,Object> (which we actually use to submit eg. java.util.Date's), but the signature for the Map of submitStartFormData is Map<String,String>.

We tried adding the variables after the start via something like this:

processInstance = getFormService().submitStartFormData(processDefinition.getId(), formValues);
getRuntimeService().setVariables(processInstance.getId(), dataMap);
‍‍‍‍

but obviously the second statement never gets executed because the start of the process causes exceptions about unknown expressions/process variables.

Any other Ideas or hints besides converting all entries in the dataMap to Strings and handling everything as String in the Workflow?

Thanks!

Providing log of thrown exceptions could help in understanding what's wrong.

Hi,

it's not the point of thrown Exceptions.

The point is, when starting a workflow without any start form parameters i use a Map<String,Object> for the variables. (eg. to suppy directly a java.util.date)
When starting a workflow with Form Paramers i can only submit formValues as <String,String>. So I can't supply e.g. a Date directly for later usage in the workflow.

Ideally the submitStartFormData method needs an additional Map<String,Object> for the "regular" workflow variables…

Thank you.
