http://vm1021.servername.ads:8080/BOE/OpenDocument/opendoc/openDocument.jsp?sType=wid&sIDType=CUID&iDocID=AeoMSw_EEvJHo6UbGiEG3CI"

That works fine but i don't find any hints or URL-sample for a Design Studio.

need i for open a "Design Studio" via opendocument an "sType" ?

when yes what type is it?

i try it without the sType and the message is "can not find the document"

Who know's the URL-term to open a Design Studio via opendocument?
