Tooltip Problem with Synth

Hello,

i have a very strange behaviour with Tooltips in Synth. I created a
component extending JTextField using a own Tooltip. First time the
Tooltip appears there are no problems but from second time on i get an
Exception. To demonstrate the problem i created a very simple class
which containes all the necessary parts to demonstrate the behaviour.


public class MyToolTipField extends JTextField {
JToolTip tooltip = new JToolTip();


@Override
public JToolTip createToolTip() {
if(this.tooltip==null){
this.tooltip = new JToolTip();
}
return this.tooltip;
}

}



the Exception is:

When i do not user Synth but e.g MetallLookAndFell i do not have these
Problems.

Has anyone a comparable Problem an maybe allready solved it?
Maybe the Problems is how i defined the Tooltip in my Synth-xml file?


<style id="tooltip" clone="default">
<insets top="1" left="5" bottom="1" right="5" />
<state>
<color idref="colorFormTextRegular" type="TEXT_FOREGROUND" />
<color idref="colorSelectTextBackground" type="BACKGROUND" />
</state>
</style>
<bind style="tooltip" type="region" key="ToolTip" />



Thanks for any help
