The first page isn't shown dynamical. The events will be retrieve from the database and list on the page together with their correspond ID. When user select certain events, the page will send these selected event IDs (e.g 123,234) to the second page, the push page, and it will shows the sub-events according to the Event IDs passed. This push page is dynamical where it can grow and shrink in time.

The push page that I am testing currently was using DynaMetaPushTable with COMMAND mode (the second page mentioned was this page actually), just that it doesn't has the grouping feature, it will receive and show all the pushed sub-events. And I would like to add the grouping feature into it.

I'm thinking since the Event ID(s) was passed from the first page, can the sub-event(s) shows according to the Event ID(s)? Can this be done?
I have try to add some validation checking on the onChangingValues and onItemUpdate handler but it seems not working
Is there any demo on this kind of circumstances and MultiDynaMetaPushTable?

Thank you.
