Tree2 examples can result in "Invalid bitmask error"
----------------------------------------------------
Key: MYFACES-531
URL: http://issues.apache.org/jira/browse/MYFACES-531
Project: MyFaces
Type: Bug
Versions: Nightly Build
Reporter: sean schofield
Assigned to: sean schofield
Fix For: Nightly Build
If you click on the folder (as opposed to the +/- nav icon) of a node that has
server side toggle, you will get an Invalid Bitmask exception. This is because
the folders have commandLinks associated with them and they are toggling the
state of the node regardless of whether the node is a leaf or not. Even though
the TreeBacker adds the empty nodes as branches, the isLeaf method of
TreeNodeBase is returning true b/c the child count is zero. (That's a new
twist to prevent the +/- icons from showing up on empty nodes.)
Solution is to remove the commandLinks from the folder nodes and only allow
expansion of the folders by the nav icons. Its possible to use <h:commandLink>
in your folder facets by writing an actionListener that would check the leaf
status before toggling the expanded state but that is an exercise left to the
user.
I will also add a simple example that does allow <h:commandLink> (and disabled
navigation icons). This example will conditionally render the command link
based on the leaf status.
