Description

ISIS-718 seems to be the culprit; we clear the action model's arguments for an action panel because it may get reused, however this same action model is cached by the collection model of an action that returns a standalone collection, and re-executed after the bulk action is performed. This results in a NPE, because those arguments were cleared.

The fix (a fix) is for the collection panel to clone the action model.

This issue discovered during voting for 1.4.0; rather than pull that vote, suggest we fix in a patch release 1.4.1
