Hi Maxim, This is not intended that the dialog flickers... This is weird and I don't see any reason (and I don't see this on my side...)
Can you run the "upload dialog" sample of wicket-jquery-ui-samples to see if you do repro it ? > git clone https://github.com/sebfz1/wicket-jquery-ui.git > cd wicket-jquery-ui > mvn clean install > cd wicket-jquery-ui-samples > mvn jetty:run (AFAIR) Thanks in advance, Sébastien
