I just want to pass on the solution for a problem I had with getting a form to render correctly within a tabbar. What was happening was that the form was being displayed, but without the correct styling: no checkboxes, no radio buttons, mispositioned labels, etc. I suspected a CSS problem but couldn’t track it down.

I used the .setSkin() property to associated the ‘dhx_skyblue’ skin with the form, and now everything works.
