-------------------------------------
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
