> Migrating from jsf1.1 to 1.2 I had the following issue:
> Caused by: java.lang.NullPointerException
>       at 
> org.apache.myfaces.custom.htmlTag.HtmlTagRenderer.encodeBegin(HtmlTagRenderer.java:78)
>       at 
> javax.faces.component.UIComponentBase.encodeBegin(UIComponentBase.java:596)
>       ... 49 more
> [2008-12-30 22:43:01,640] [http-8080-2] [WARN ] 
> org.apache.myfaces.renderkit.html.util.ReducedHTMLParser - Invalid tag found: 
> unexpected input while looking for attr name or '/>' at line 42. 
> Surroundings: '<!DOCTYPE html PUBLIC "-//W3C/'.
> Reason:
> Worked in jsf1.1:
> ...
>   <t:saveState value="#{projectsBean}"/>
>   <h:form>    
> ...
> Now causes a NPE. So I had to exchange the directives to:
> ...
>   <h:form>    
>   <t:saveState value="#{projectsBean}"/>
> ...
> Took me 1 full day... :-(
