Hello
Before I put my questions I would like to make something clear to others not to pull out some hairs or wasting hours to find the cause:.
If you use a generated Apex tree (widget) and you want to access it by API you will get some confusing error messages and there is no help in the API itself telling you why. The way to access a generated tree is :
On Tree region level add an ID in 'Static ID' (f.e.: HIERARCHYTREE)
Access the Tree widget in Javascript by $('HIERARCHYTREE**_tree**')
The API documentation (I'm not allowed to link it here) is even misleading using the class identificator (dot notation) in the samples. So don't get confused about that.
Questions:
I would like to add and delete nodes in the generated tree. The API documentation does not provide ANY samples how to add or delete a node. I even searched here (spyglass on top) for "tree" but no result. So if you know any source on the Internet or a book providing examples I would be thankful..
I would like to react in the background if the user clicks on any treeview entry (node, child). The API doesn't support simple click events. How can I (simply) add a one-click event on any entry of the tree?
To add a node I guess I have to use the "addNode" option described in the API. It's already unclear how to get to those parameter: addNode(pParent, pIndex, pLabel_opt_, pContext_opt_, pCallback) -> f.e. HOW can I get the PARENT node into which I would like to add a child? There is function to get children but no function to get the parent of f.e. the selectedNode. pIndex: Why the heck do I have first to evaluate the amount of children of the node I would like to add another node(child) in order to get the amount of children and therefore add it at the end? As I'm using the default generated tree how can I pass the ID provided by that defaultNode?
I think with some simple code samples the questions of topic 3 will resolve themselves. So if you know any source where to find simple examples to add and/or delete nodes by API be would great.
