How to populate pyClassName in steps of a DataTransform?
When I open a DataTransform in Designer Studio, the pyClassName of each step is empty (you can see in Clipboard or XML). If I want to call to another DataTransform in one step and the Class is empty, how is it calculated before opening the proper one? How could I populate the pyClassName?
I had a similar question for Activity rules, and I found that the pyStepsClassname property of each step can be populated by calling the OnBeforeDisplay activity. However, this solution doesn't work fine for DataTransform rules.
