Hallo Peter,
Thanks for post. The problem is that I cannot insert my own CSS for this button... What you explain bellow I have already done for all my web app. The css for this button is "ui-button-text" but this one is globally to a lot of others button so I cannot change this css. I need to include mine there (ui-button-text my-own-css) but I found no options for this. I think it's not possible for the moment to include custom css for this button.
I hope Bruce will confirm this.
Thanks,
Robert
