Hi,
is it possible to create YAWL control flows programmatically using the API? are there any samples or guides for that? because I am unable to get started on this.

Your assistance is appreciated

I would get from a codelet the `Element` that contains the data type of a parameter.

I know that `SchemaHandler` has an useful method, `getTypeMap()`. I tried to access to `SchemaHandler` from an `YParameter`, this way:

Hello,

It seems that in YAWL you have the possibility to link the task to its external implementation in three ways:

I get an error when I try to run a custom codelet. It's a simple test codelet, that does a subtraction between two longs. The output is `z`, to not conflict with the ExampleCodelet. I added `z` to the net variables and to the task output variables. Bu I get this error:

Maybe I'm comparing potatoes with apples... anyway.
