>          Components: Viewer: Wicket
>    Affects Versions: viewer-wicket-1.4.0
>            Reporter: Dan Haywood

>             Fix For: viewer-wicket-1.4.1

> 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
