             Summary: RuntimeException when t:add property to a grid and fetching the model before grids setup render
                 Key: TAP5-2470
                 URL: https://issues.apache.org/jira/browse/TAP5-2470
             Project: Tapestry 5
          Issue Type: Bug
          Components: tapestry-core
    Affects Versions: 5.4
            Reporter: Dimitris Zenios
            Priority: Minor


If we have a grid with a t:add property and a mixin that on SetupRender gets the sortModel and applies sorting, then on the grids SetupRender we get a RuntimeException "Bean editor model for %s already contains a property model for property '%s'.".

This happens because on grid line 510 we set the previous dataModel to null and recreate it.When the model is about to be created again we try to add the extra properties again with BeanModelUtils.modify resulting to the exception mentioned above
