Every time I try to open my portlet with IE9 the following error turns up:
[POP.012.0002.wm_cafshared/hidden] A client error occured processing
the response from the server.
Error
Member not found.
undefined
I don’t think this is a IE9 issue because when I upload the same portlet to another MWS server the portlet runs just fine on IE9, so my guess is this is a MWS issue.
This is what i would guess is occurring. While some portlets may work fine in IE9, other portlets will probably be using different controls. Those controls leverage other javascript files. Those other javascript files are probably not functioning correctly in IE 9 for a yet un-diagnosed reason.
