I am trying to build a report that displays a table with variable number of columns and content.
I have myTable that is connected to a dataSet
1. In beforeFactory I call SQL function that returns a query for my data (I am doing this using a different data set - just for this purpose).
2. In beforeOpen of my dataSet, I set returned query as a querytext for this dataSet.
3. In afterOpen, I set result' s metadata to global variable so they could be later used.
4. In onCreate of myTable I read the metadata and iterate over them, so to create columns and binding of the table.
Though it appears to be too late - even though the column number and names are correct in the metadata, myTable columns are not created.

I tried to move the code to tables's onPrepare, but then my metadata is empty as dataSet opening is only triggered after onPrepare.

Any clues, how could I modify the table columns based on the underlying dataSet results?
