problem with <p:graphicImage update does not work

[rvecchio1]

Updating the version of primefaces 3.5 to 4.0, the following code does not work anymore. Does not update the image, but if I perform a reload (F5 or CTRL + R) the new image is visible.

Does anyone have a solution? Help!

use forum search... already fixed in elite releases.

This is one of the reasons, I honestly think te fist 2 or 3 'elite' releases should be publically available. It's kind of not 'appropriate/fair/nice' that fixes for regressions like this are only available for elite members.

+1 from my side - but it's not my decision
