my problem is :a background image couldn't be loaded at the first timewhen reloading the page it appears normally
note : the image is defined as ExternalResource, and it's put in the webpagesVAADIN directory
any help ?
sorry , it's not an ExternalResoerceit's like this :canvas.drawImage("VAADIN/compass.png", 0, 0);
this.requestRepaint();solves the problem, but i don't know the reason of not loading it at first time
It seems you are using an add-on. Check if it has a bug tracker or a special forum post to contact the author.
I would help to know which add-on, in which version as well as what browser you are using.
If you can make a small demo application with the same problem it would make it easier for somebody to take a look and fix it quickly.
