Re: Instanciate a DataNode wihout DataObject to display some properties

Ok thanks, I successfully created a BeanNode with the appropriated createSheet method. This seems to work.

Sorry for the next stupid question but I am unable to publish the Node into the Global Lookup… I have a table in the TopComponent, I listen for row selection and then I would like to dynamically update the exposed Node. I tried this first:

lkp = new ProxyLookup(super.getLookup(), new AbstractLookup(ic)); // in the constructor

with:

@Override
public Lookup getLookup() {
    return lkp;
}

And then I use the InstanceContent ic to manage the content of the Lookup. Unfortunately the following the always return null:

Lookup.getDefault().lookup(MyBeanNode.class);

I also tried this:

ExplorerManager em = new ExplorerManager();
associateLookup(ExplorerUtils.createLookup(em, this.getActionMap()));

and then:

Node[] nodes = new Node[1];
nodes[0] = myBeanNode;
em.setSelectedNodes(nodes);

Also without success.

Publishing a Node in the Global Lookup should be very standard… Sorry for this stupid question.

BeanNode or just a subclass of AbstractNode.  DataNode is only useful for something that represents a file and you want to use, say the Save action or other file-related actions and want a lot of the plumbing for those built-in.

Maybe you're looking for BeanNode?

Hello,

Is it possible to have a DataNode without any DataObject? If possible I would like to publish it in the Global Lookup and use its createSheet method to display some info in the Property window. I work with beans that don’t necessarily have any associated file on disk.

Not sure if this approach is correct.
