Joern Kottmann commented on UIMA-2273:
--------------------------------------
Exactly, if the input is changed to a document which cannot be loaded (e.g.
type system problem), then the view page should just swapped to one which shows
an text message. The same issue exist on a view change.
I will try to define a base AnnotationViewPage which contains a PageBook which
has a message book and a user created control. The user part will then be
disposed/created when the editor input or CAS view changes.
> Let CAS Editor implement IResourceChangeListener

> Some functionality to automatically update a opened CAS in the CAS editor if
> the file was changed would be really nice. I don't know for sure, if this
> functionality is missing or I simply didn't find it in the code and in
> Eclipse. In any case, I haven't found a IResourceChangeListener
> implementation and that is how I would have done it.
> The general communication shouldn't be a problem to implement, but - in my
> experience - updating all necessary elements can be tricky. The interface for
> changing a view can maybe be used and has probably to be extended.
