Collection in a table column
I have a Node "a" with 3 attributes (date, tooltip, category) maped to a DateNavigator.
Then I have another node "b" with two attributes (date, tooltip) maped to a Table.
I want to do the next:
for each node element "a", catch every diferents dates and put the tooltips asociated to them in a collection that would be the "tooltip" attribute from node "b".
Then, map dates to the header from the table, and the tooltips collection to the column.
