[RFH] A trivial question about Nodes

[Imran M Yousuf-4]

Hi,

I am a newbie to NetBeans RCP and have been working with the Nodes
API. In this regard I am facing a issue which I am not sure whether is
expected or not, I would be grateful if someone would please help me
:). The problem is - I am using a bean tree view and I have
NodeActions'. When I double click it (after setting it as preferred)
it throws the event with the selected nodes but if I right click the
node and then invoke the action it does not throw the event with the
selected nodes :(. Is this normal? If not please provide me some
pointers and please dont hesitate to ask questions :).

A quick response would be extremely appreciated and benevolent.

Best regards,

It isn't normal if you have any action showing up on the popup when clicked does not perform its function unless it is showing as disabled. Have you debugged and stepped through your code? Which version of the IDE and platform are you using (NB 6.0, 6.1, 6.5 (dev or milestone))? If you set break points in different methods of your action class does the debugger stop any where? For instance, watch enabled and the different actionPerformed methods you may have depending on your super class.

Hi Wade,

Thanks for the reply :), I actually found the solution to my problem
by digging more deeper into Lookup and NodeAction code. I was missing
getLookup method from my topcomponent thus not exposing my Nodes what
so ever. The reason for double click or preferred action wondering
lies in the implementation of NodeAction.actionPerformed
implementation where it first looks whether the source is either a
node or node[] if yes calls the performAction(Node[]) else goes the
lookup way. BTW I am using NB 6.1.

I hope this answer is logical.

Best regards,

Imran

Code I was missing from TopComponent was:
    @Override
    public Lookup getLookup() {
        if(lookup == null) {
            lookup = ExplorerUtils.createLookup(em, getActionMap());
        }
        return lookup;
    }
