Hello everybody,
this topic is for the people which have some experience with EventList and FilterList.

in the Eclipse Papyrus project, we developed table using ArrayList to store rows and columns elements. It works very fine, but now we would like to integrate filter capapbilities to our tables. So I would like to replace my ArrayList by FilterList to be able to use DefaultGlazedListsFilterStrategy like in the nattable example.

Do you now if I can have problems doing this or it is a safe change?

Regards,

Typically this should be safe. GlazedLists are "simply" a transformation on top of another Collection like ArrayList. So I don't know a reason for not using it.

Hi Dirk, thank you for you answer.
I was afraid to do it, because in the Tree Table developed in Papyrus, I already replaced ArrayList by TreeList for rows and TreeList.clear() and TreeList.remove() gave me some problems due to the hierarchy.

Well, TreeList is officially a "developer preview". And AFAIK you should avoid operating on TreeList itself. For removing and clearing you should operate on an underlying EventList, since the events fired then should be correctly handled by the TreeList.
