Access to a WritableList [message #502439]

Hallo,

iam work with a tableviewer and a writablelist.
The writablelist contain the data for my viewer.

My Problem:
I work with swtbot and want access on the writablelist,
but i receive many exceptions :
"Getter called outside realm of ovservable .... WritableList"

I have solve this problem so:

UIThreadRunnable.syncExec(new VoidResult()
        {
            public void run()
            {
                assertEquals(bot.table().rowCount(), ModelProvider.getInstance().getInput().size());
            }
        });

Is this solution okay, or know some of you a better solution?

P.S. the ModelProvider is a Singleton which contain the WritableList. getInput() is the getter-Method for the WritableList

The assert that executes in a uithreadrunnable is not really caught by junit. I'd recommend having the uithreadrunnable return an int and write an assert like you'd normally do.

In your case, I'd recommend writing the test like this:

public void testFoo (){
assertEquals(5, syncExec(new IntResult(){
public int run(){
// return the count
}
}));
}

Also this seems more of a unit test to me that verifies the content provider. It might be cheaper to just new up a provider, shove in an input, and test the getElements() method Smile
