Mashup for moving custom fields

Hi,

I have created a mashup for moving some custom fields to their own tab in the detail view. It is working, apart from some quirks. I would like some help in resolving the quirks.

If I open the tab I created, the static markup I create in the mashup gets rendered, but the moved fields don't show up. When I refresh the browser, they do show. The static content is rendered in the addTab function. The custom fields are moved to pre-defined <div>s that are in the static content, this happens in the onRender function.
In the process of moving the custom fields, I add some explanatory text to each field's label. This works fine, until I edit the value of a field. In that case the whole field, including the label, gets re-rendered and my explanatory text for that field gets lost. Doe you have any suggestions how to resolve this?

Best regards,
Bart Kummel
