Hello!
I use SWTBot to test my UI.

In my test i start the UI and close the welcome window:

SWTBotView eclipseView = bot.activeView();
if (eclipseView != null && view.getTitle().equals("Welcome")) {
eclipseView.close();
}

After that i set the perspective:

bot.perspectiveByLabel(perspective).activate();

And after that i will do this:

bot.menu("File").menu("New").menu("Java Project").click();

I will open a new java project and at this point i get an error like this:

Error in --> AbstractSWTBot.class:

public AbstractSWTBot(T w, SelfDescribing description) throws
WidgetNotFoundException {
if (w == null)
throw new WidgetNotFoundException("The widget was null.");

...
}

Error Trace:

org.eclipse.swtbot.swt.finder.exceptions.WidgetNotFoundException: The widget was null.

Any ideas or hints what may be the cause of this?
Thanks!

Hi

which perspective are you switching to? Because "Java Project" is
available right after "New" only in the Java perspective... you may
want to try this code which should work with all the perspectives

bot.menu("File").menu("New").menu("Project...").click();

SWTBotShell shell = bot.shell("New Project");
shell.activate();
bot.tree().select("Java Project");
bot.button("Next >").click();

hope this helps
Lorenzo

Thank you very much ... it works, but after the code:

bot.button("Next >").click();

I create my new Project File with:

bot.button("Finish").click();

The project is created, but after a short while i get this error:

You should increase the permgen space in the launch of your swtbot test...

I usually do that by setting these arguments in the launch

-Xms40m -Xmx384m -XX:MaxPermSize=256m

hope this helps :)
cheers
