NetWeaver JSF rendering document type is not supported

I developed a very simple JSF application in SAP NWDS with the "SAP Component Library for JSF".

I run the JSF application (code below) and I get a popup alert with this text:

Fatal application error: The standard rendering document type is not supported. Contact your administrator

I have no idea what the "standard render document type" is and where I can configure it.

Any ideas or hints?

JSF application:

Solution

  • The Problem was the line 

    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

    It seems that this LSF-Framework gives the DOCTYPE in the <f:view>-Element and the error is related to the second doctype
