WF Binding

[Paul Batey]

It sounds as though the value you would like to put into your task text is the result of a method.  The only ways you can do this are:
 
1) Have a previous step that executes the method and returns the value to the workflow container (you need to create a compatible workflow container element).  This can then be passed into the next task (again create a compatible task container element and flag it as import) where you can use is as an expression (I think that's what Mark was getting at)
2) If the method is just returning a list of values related to the object (i.e. it is just information and not an operation), perhaps you should consider using an attribute instead of a method.  Then you can use the attribute in the task text without a previous background step.
3) Use programmed binding.
 
As Mark says, the result of the method is after its execution so the task.
 
Cheers,
 
Paul

Here is what I need to know. Would like to insert some values in Description
Tab using Insert Exrpression coming from the Task which in turn is getting
values from the Business Object.
Or if there is any other alternate way todo it.

Would appreciate it.

Thanks.
