Description Jan Lahoda 2004-07-08 15:27:02 UTC 
org.netbeans.modules.spi.project.ui.LogicalViewProvider
CVS revision 1.6,
org.netbeans.modules.project.ui.ProjectsRootNode
CVS revision 1.22.

The javadoc of LogicalViewProvider.findPath claims
that the root argument is "a root node from
createLogicalView". I understand this in such a
way that the root == result of (some recent
invocation of) createLogicalView. But, current
ProjectsRootNode sends different node (subclass of
FilterNode, ProjectsRootNode$BadgingNode) into the
findPath method.

Please either:
-clarify that the root argument of the findPath
method can be a wrapper node around the node
returned from createLogicalView and either provide
means of getting the original node or clarify that
the implementor is responsible for getting the
original node.
-send the same node as was returned by the
createLogicalView into the findPath method.
Comment 1 Jesse Glick 2004-07-08 16:28:15 UTC 
It think it is the former, i.e. a wrapper node can be passed, and that
fP impls should use nodes properly, i.e. by checking cookies/lookup
only, and never relying on impl class. But will leave it to Petr to
confirm and clarify.
Comment 2 Jan Lahoda 2004-07-08 18:14:51 UTC 
Just a note: in the case 1, gathering the original node is invalid, as
the children of the wrapper root node may (not sure whether they are,
not tried) also be FilterNodes, and in this case it would probably be
awaited that the findPath method returns appropriate FilterNode, not
the original node. Therefore lookups (or cookies) of the Nodes should
be used.

After thinking about it more, it seems to me that the case 1 (wrapper
node is allowed) makes more sense than the other case. Therefore I
suggest that the javadoc is modified to reflect this.
Comment 3 Jesse Glick 2004-07-08 19:00:47 UTC 
Good point - if the root is a filter node, its children must be as
well. (A Node can only belong to one Children at a time.) So passing
in the original root node would be useless - you would find the
original child, but then you would still not know which filtered child
that corresponded to.

I think it is OK now (LogicalViewProvider revision 1.7).
