It would be very beneficial if you could make an action event occur when a column is marked. This would allow you to create drill through for any type visualization regardless of the type as well as data manipulation which might need to be done if certain data is marked.
I've published an example demonstrating my nasty methods to achieve this in the wiki :)

I'd still obviously prefer Tibco to implement a proper solution!
I have requested something similar which is to expose more events via the UI onto which you can attach scripts. So expose events like "OnMark", "OnUmark","OnFilter","OnPageActivate" etc.
Pete, can you attach an example file?
In the past I've worked around this by a text area on the page with a hidden calculated field that reacts to the marking and a hidden property input control. I then have JavaScript that detects when the value changes and enters it into the input control. allowing me to have a property script fire when the marking fires. Horrible solution, but it's worked...
