Big mess. Select node, replace it, get error on the event listene r.

[Filipe Marinho <fi...@SE.EFACEC.PT>]

Hi!

First of all, i would like to thank all the participants of this mail list
that helped me and all the people with problems.

Talking about a problems i have other one:

Some where along the time of my application i replace nodes of my svg. That
nodes had listeners (ex: mouseclick listener).
So i have to add a new istener to the element that was inserted. 

/*.....*/

jsvgCanvas.getUpdateManager().getUpdateRunnableQueue().invokeLater(new
Runnable(){

/*......*/

		    //add listener
		    Node target = doc.getElementById(uid);
	    	EventTarget et = (EventTarget)target;
	    	et.addEventListener("click", new mouseClickListener(),
false);
/*.....*/ }...


This is what i do to add the listener to the new element.

So far so good...

The element i replace is a text element. If i select the text of the element
i am going to replace and then replace it for other text element the new
text keeps selected. My problem is that when i click on that text (with some
text selected) i have the error:

java.lang.NullPointerException
	at
org.apache.batik.gvt.text.ConcreteTextSelector.checkSelectGesture(Unknown
Source)
	at

	at org.apache.batik.util.RunnableQueue.run(Unknown Source)
	at java.lang.Thread.run(Thread.java:534)

instead of the action of the listener. This error only happens when i click
on the replaced element witch is selected because the old text element was
too. otherwise no error is shown.

If you could help me with this....

thanks....
