Server cannot set status after HTTP header [v2012.2.1400.0]

[Gui]

Hi,

Recently I've seen my exception log filling up with exceptions from the report designer,
I don't think the problem is visible from the user POV (no complaints from users), it's just visible when logging errors from the Global.asax:

Code: Select all

System.Web.HttpUnhandledException (0x80004005): Exception of type 'System.Web.HttpUnhandledException' was thrown. 
---> System.Web.HttpException (0x80004005): Server cannot set status after HTTP headers have been sent.

I'm adding the module to the page Controls at the Page_Load. Do you have any idea how I can prevent this exception?

Thanks in advance,

Guillaume
