Hello, I have a problem with resetting the state of tree2 component.
On my JSP, I have the tree2. I f the user clicks on a node, the node is marked as selected and highlighted with css. This works fine. Also on the page, there is a commandLink "Reset", which should resets the tree (default is, that the root node is selected). In my reset method in the ManagedBean, I'm creating a new treemodel, setting the path to the selected node, and adding the model to the tree. I have tried both options, recreating model and tree and only updating the model. Nothing worked as expected. In both cases, the old node is shown as selected. I have debugged throw the code and in theBackingBean, everythink is correctly set. I can see the variables of htmlTree and treeModel and everythink looks like expected. Then I have debugged the isNodeSelected() Method of the tree, and I can see, that the getDataModel() Method of UITreeData returns a _cachedModel variable which contains the old model, with the old selected node. And this model seam to be used for rendering the jsp How can I reset the selection reset correctly? I found something in further posts on the maillinglist, but it does not worked for me (http://markmail.org/thread/mbvpuuw7egyndnbt) Thanks a lot!
