Removing node from JSF TreeModel tree?

I have faced some problems with removing node from JSF TreeModel tree. Is it possible to somehow remove node from TreeModel object?

Please see snippet below:

TreeModel treeModel = getModel();
for (int j = 0; j < treeModel.getRowCount(); j++) {
            MyTreeNode node = (MyTreeNode)treeModel.getRowData(j);
            if (node.needsRemoval()) {
            }
        }

Your assistance is very appreciated! Thanks!

Solution

  • Found answer - TreeModel extends DataModel class, which is abstraction around data collection provided in setWrappedData() method. So as far as I understood, there is no way to change tree model nodes, however you can tamper with data collection and reattach it with setWrappedData(). Please let me know if I am wrong.
