Commented Issue: "Extender controls may not be registered after PreRender." [27131]

Hi,

I got this error on postback of a page where I add dynamically the HtmlEditoExtender control. (all controls are reloaded if Page.IsPostback in the onInit event).

It seems to be a common issue but I found no relevant solution.

Thanks.
Comments: Ok, I got it at last. The controls must be re-instantiated after postback, not re-used from the collection kept in memory.
