[Trinidad] Problem on SAP Netweaver 7.11: Circular include of base-desktop.xss detected

[Pavol Valko]

Hello,
I have problem running Trinidad on SAP Netweaver 7.11 j2ee server.
Exception is thrown in System.err(see at the bottom) on page loading,
but page is displayed almost as it should be. Symptoms are that command
link does not work and styling of tables, tabs etc. is not proper. I
notice that almost no javascript is added to rendered page (e.g. command
links with no onclick action..). Also generated css seems to be too
short, only about 10 lines. Command buttons work.
I tried the most simple configuration that I found on trinidad page and
in examples. I suppose that server use JSF Sun RI 1.2_08, that cannot be
changed.
Please can anyone help to solve this? Deploying on this server is
critical for my project. Thanks.

My test page look like this:
<?xml version='1.0' encoding='UTF-8' ?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.0"
        xmlns:f="http://java.sun.com/jsf/core"
        xmlns:tr="http://myfaces.apache.org/trinidad">
        <jsp:directive.page contentType="text/html;charset=utf-8" />
        <f:view>
                <tr:document>
                        <tr:form>
                                <tr:commandLink id="testLink" action="test" text="to test" />
                        </tr:form>
                </tr:document>
        </f:view>
</jsp:root>
