Hi
I'm making a GEF editor and need to create a pop-up window. The editor
contains an UML2 diagram and by pushing a button on the pallette it
creates a *.uml2 file. This part is implemented, but I would like to have
a pop-up window telling if the *.uml2 file is created OK or if there are
any problems. This means I only new pop-up containing some text and a OK
button. I have tried to implement a MessageDialog like this:
...
String []buttons=new String [1];
buttons[0]="ok";
MessageDialog msgD = new MessageDialog(null,
null,
null,
"Hello",
MessageDialog.NONE,
buttons,
0);
msgD.open();
...
The dialog activates and says "Hello" but I get a NullPointerException
when the dialog is closed.
Anyone have any idea why?
And what should I do to avoid it?
The stack trace is as follows:
java.lang.NullPointerException

The viewer lost focus during a mouseclick, which sets the viewer to null.
Can you post your modified code?

Are you using the most recent 3.1 builds? If not, please try them.
I'm looking for your drag trackers code for button up.

I have not implemented any drag tracker code for button up.
Or at least not that I am aware of. The tool creating the pop-up window is
a subclass of AbstractTool. AbstractTool already have a handleButtonUp()
method implemented. (I that is what you mean)...
