Sounds like your making calls on the tree node (as opposed to the model).<br />
The tree node do not support firing TreeModelEvent's.<br />
If you change your nodes you must also ensure that the matching events are fired by your tree model.<br />

The events are minor problem. Give me example how to dinamically change structure of one node( remove all its childrens and add new ones)!

I have JTree which a fill with nodes at the first time.<br />
After that a call removeAllChildren() method for some node and I am adding a brand new set of nodes as childrens for this node. Why the JTree doesn't changes? (There are only interrupted lines to previous childs which are still visible)!

JTree question

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
