Nebula DateChooserCombo Errors on Run

[Jonah Bron]

Hello, world!

First, I am really loving WindowBuilder. Before, I was doing it by hand, and that wasn't very efficient.

Okay. Problem. Whenever I put a DateChooserCombo into any window, it works fine if I click the test/preview button. I click the calendar button, and it comes up just fine. But, If I compile and run the actual program, it gives me a very long error if I click the calendar button, with apparently no errors in my actual program. Everything works fine, but it dies if I click the button. Whether you need it or not, here's the error:

Code: Select all

Test case: create a new window, insert a DateChooserCombo, run, click calendar button. When run in debug mode, it stops when the calendar button is pressed, and opens org.eclipse.swt.widgets.EventTable. When resume is clicked, it dies and gives the error. Does it work for you?

Thanks for the help!

I tried that and it worked just fine for me.

If I had to guess, it looks like a classpath issue.

Do you have the Eclipse JFace plugin on your classpath?

[Jonah Bron]

Thanks for the reply. Hm, how do I check? I tried googling it, but no joy.

P.S., looks like you're one of only two people on here answering questions!

[Jonah Bron]

Never mind, thanks very much for your help. I found out how to do it here:

http://wiki.eclipse.org/index.php/JFace ... ce_Project

For anybody experiencing this problem, if you already have SWT installed, skip the installing part and go straight up to adding the variable to project org.eclipse.swt.

Thanks again!

Actually, I'm just the front man

I have an entire Google team behind me doing all of the hard work and feeding me any answers that I don't know.

Any names that you see show up in red are also members of our team.

That makes it easy on you...

Thanks again
