I have an issue to create a something like a rectangle, which would be refreshed very often (on the client side only) and partially filled.
In HTML5 there is a canvas element which is very useful for me.
I've tried to simply put a canvas in <verbatim> tags, but when I resize the browser it overlaps other components.
Mayby somebody knows whether I can use some existing component or create a custom one which would meet my needs.
Depending on what frequency of refresh you need you can use an af:poll or the Active Data Services approach.
