Matt Cooper commented on TRINIDAD-1834:
---------------------------------------

I believe this patch will have a drastic negative impact on performance since 
with this patch, undisclosed content will be processed.

> tr:showDetail prompt facet doesn't fire ActionEvents if it's closed

> source=" /images/bearbeiten.png" />
>           </tr:commandLink>
>       </f:facet>  
> ...
> </tr:showDetail>
> The actionlistener should also be invoked if it's closed. the same applies to 
> input components and validators.
> In processDecodes, (processUpdates, processValidators) in UIXShowDetail class
> , facets and children will only be processed, if the components is disclosed. 
> But facets should be processed in closed and disclosed state.
