I'm working on some enterprise portal modifications in AX 2012 and ran into the following issue:
I have a listpage with multiselect enabled. The selection made must be passed to the next page, which is opened by clicking a menu item on the actionpane. However, I don't know of any method to get the multiselection of the previous page. When I use an action menu item, I can get the multiselection from the Args parameter (args.multiselectioncontext()), but this parameter is not available when using a URL menuitem. I can get the currently selected record of the previous page, but that's only one record.
So the question is: when originating from a listpage, how do I get the multiselection from the grid of this listpage on the next page?
