Good afternoon Bernard.

I have added the Syntaxhighlighter jar to my web application (Rich Faces 4.1 Final, Glassfish 3.1) and I am receiving a null pointer exception when I access the page with my Syntaxhighlighter tag.  Here is the contents of my error:

Any thoughts on the issue?  Any help is greatly appreciated.

Thank you.

Thank you for the response Bernard.  I didn't realize the highlight attribute was required.  I have added it, but the my output is displaying as plain xml.  Here is the markup from the page.  My managed bean method (srcDocs) is obtaining the xml from a JPA entity.

<h:form>

                <rich:tabPanel rendered="true" id="tabPan1" immediate="true" switchType="client">

                    <rich:tab header="Source Document" id="tab1" rendered="true">

                        <syn:syntaxhighlighter id="syn1" theme="default" language="xml" highlight="2" >

                            <h:outputText value="#{transactionController.srcDocs()}"/>

                        </syn:syntaxhighlighter>

                    </rich:tab>

                    <rich:tab header="Destination Document" id="tab2" rendered="true">

                       <syn:syntaxhighlighter id="syn2" theme="default" language="xml" highlight="2">

                            <h:outputText value="#{transactionController.srcDocs()}"/>

                        </syn:syntaxhighlighter>

                    </rich:tab>

                </rich:tabPanel>

            </h:form>

I guess I should say that I am not exactly sure how to implement this tag properly....

Any thoughts on this one Bernard. My app is still displaying plain XML in the syn tabs.
