dialog

[Adejuwon Omolara]

Hello. I have been trying to lay my hands on why the dlgRight.show() line has been throwing an error (arrayindexoutofboundsexception 0>=0) and I dont seem to get the reasons. Any kind of help will be appreciated.

The snippet shows how it has been declared

 

                                Label rightLabel = new Label(right);

                                Dialog dlgRight = new Dialog("CORRECT");

                                dlgRight.addComponent(rightLabel);

                                dlgRight.setTimeout(1000);

                                dlgRight.show();

                                showForm("DisplaySim", null);

Your code seems fine, can you post the full stacktrace? it would help us understand what went wrong

Hi,

The stack trace indicates your local libs are out of date, can you please update your local libs and try again.

go to "project properties"->"Update Project libs" 

[Adejuwon Omolara]

Thank you. I tried updating and the return message was that it is already up to date. Though I have refreshed.

Best Regards,

Adejuwon Omolara

Are you changing things in a separate thread?
Can you turn on the EDT violation detection switch in the simulator?
What do you have around line 329 within your state machine class?

[Adejuwon Omolara]

I am not using a thread. The code on the line 329 is the dlgRight.show();

Best Regards,

Adejuwon Omolara

You can be on a separate thread by using a timer or networking and quite a few other things.
Its just really hard to understand what you are doing to reach this point? What do you have in that area? What else is executing?
