Hi Volker,
thanks for your hint. I think I get the idea. From within the jsp page you call
some function which then uses the tobago class implementing the tag library
directly. This way nothing needs to be compiled.
I tried to follow your directions but I still fail to get the link from the jsp
to the controller code. I am using something like:
<tc:panel id="content" binding="#{myBean.generateComponentTree}">
<%-- content filled by application --%>
</tc:panel>
In the hope to receive a call into myBean and a matching method. However, I
only get exceptions like:
javax.faces.webapp.FacesServlet.service(FacesServlet.java:152)
org.apache.myfaces.tobago.webapp.TobagoMultipartFormdataFilter.doFilter(TobagoMultipartFormdataFilter.java:70)
org.apache.myfaces.tobago.application.ViewHandlerImpl.renderView(ViewHandlerImpl.java:149)
org.apache.myfaces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:367)
javax.faces.webapp.FacesServlet.service(FacesServlet.java:138)
org.apache.myfaces.tobago.webapp.TobagoMultipartFormdataFilter.doFilter(TobagoMultipartFormdataFilter.java:70)
Could you shed some light on this link, or maybe point me to some documentation
or an example?
Am I supposed to write a complete Tag like the InExtension tag myself, and
place this in the panel ??
Thanks for any ideas,
Peter
