Hi there,
right now I’m trying to make a table that gives me different context menu options when different ammounts of rows are selected. I already found out how this problem was solved back in vaadin 6. Just add a requestRepaint in a valuechangelistener and the Action Handler would update with new Actions, if specified. Unfortunately this doesn’t seem to work anymore.
Just for checking, my Action handler code:
public Action[] getActions(Object target, Object sender) {
// return actions;
Set<String> test = new HashSet<String>((Collection) table.getValue());
if(test.size() < 1){
logger.info("Nothing Selected");
return nullselect_actions;
}else if(test.size() == 1){
logger.info("Single Select");
return actions;
}else if(test.size() > 1){
logger.info("Multi Select");
return multi_actions;
}
return multi_actions;
}
Intrestingly enough my logger spits out the comments for the different cases whenever I select something new. But The contents of the context menu are not changed.
Table is set to immediate, multiselect. Anything I’ve overlooked?
Also, I think the ContextMenu Addon could solve my problem. But I have my problems with getting it to work.
