Hi
there is the schema instances stored under form library. The solution offers also a web part solution where schema url for schema xml instances are rendered.
Now the user does click the href-ed schema url in order to see more details on that particular schema.
Above all works right as far as the browser run on the SharePoint server machine.
Experience while trying to achive the same by clicking on schema Url in browser started from any other client machine causes file open save dialog to popup with the message like in subject. "What do you want to do with [name].xml" {Open, Save Save as}
Both CA and locale site are configured to render those xmls [forms] always in web browser.
What is causing this? Remember it works if user does select the form from the form library view, but not when same href / uri clicked from web part.
