How to notify the Collection widget from it's inner mashup ?

[seanccc]

Hi, 

I use Collection to display a list of items ,  each item has a Delete button as following.  If delete one of the items,  I need to refresh the Collection  so that only display 2 items. 

But how can I notify the collection to be refreshed from it's inner/contained mashup ?   I didn't found any event or mashup parameters can be used for this . 

Session parameter may solve it, but is there a elegant solution ?

| Delete |    | Delete |   |Delete  |
|________|    |________|   |________|

Regards,

Sean

To my best knowledge I think Session parameters would be the way to go.

You might be able to do it with a Property and a GetProperties - Push on Change setup
