Bug? - After a close page of a newedit of tab/grid #3, the selection of tab/grid #2 goes to first selection.
I have a Tab-container consisting of three tabs, each containing a gridview. Let's say those grids contain Costumer/Order/Product, each a 1-to-many relation to the next. Thus: Grid 2 on tab 2 listens to Grid 1 on tab 1. Grid 3 on tab 3 listens to Grid 2 on tab 2. When I edit an object on Grid 3 and close page, the selection of Grid 2 goes back to first selection and thus instead of seeing a grid of products of the previously selected order being refreshed, I see a grid of products of the costumer's first order. For some strange reason, the costumer grid doesn't lose it's selection.
On the tab you could set two properties, one of them is "refresh on show". I think that you have this setting set to "yes", which will reload the content of the tab.
