i don't care how koen does the generation of the .xhtml facelets template it in the gpd.  probably programmatic would be the easiest and most portable.  at runtime, the forms will be rendered with facelets.

the problem is when you want to create a form field to enter a new integer process variable.  since the task form variables are in a hash map, taskInstance.variables['myNumber'] will be stored as a string if no conversion is specified.  i was hoping that specifying a conversion on the input field could do the trick to convert the submitted text to integer before it was inserted in the untyped hashmap.

what use cases do you see other then generating forms ?  it will be a challenge to find a clean and natural behaviour of the system.  some people want to use it as a free hashmap.  others want the types of variables to be checked.  some want the variables to be created at start time, others want lazy initialization,...
