title: AX 2012 - ListPage FactBox Part does not refresh on Sub Datasources selection change
body: <p>my issue is on the ReqTransPOListPage, I added a FactBox Part related by ItemId</p>
  
  <p>When the user navigates in the Grid records
  - If the selected field on grid is one of the main DS ReqPO then the FactBox get refreshed!
  - But if the selected field on the grid is a field of any sub DataSource of Query, then PCDataSourceEventNotify.onRefresh() is not triggered and neither my FactBox.</p>
  
  <p>I can't even force refresh in ReqTrans_DS.active() since it's a ListPage based on AOT Query and datasource methods cannot be overriden.</p>
  
  <p>some ideas?</p>
