[JBoss Portal] - Request forward error with Portlet
by anantj
Hi All,
I am having a protlet web-app. Which contains one portlet and deployed on JBoss portal 2.6.2 as well as 2.6.3.
The portlet class calls one of the servlet created by me. The servlet after processing request it forwards the response to one JSP which is done using RequestDispatcher. But it gives following error.
Please help me to solve this problem.

[JBoss Seam] - Re: Two browser tabs : basic question
by damianharvey
I don't think that there's anything *wrong* with @RequestParameter, but it isn't optional so your Bean containing it must always be passed it.
Using just page params is just as easy. You would do something like this:
test.xhtml:
| <a4j:outputPanel id="testPanel">
| <h:dataTable
| id="testTable"
| var="row"
| value="#{testBean.widgets}">
| <h:column>
| #{row.id}
| </h:column>
| <h:column>
| <s:link
| action="#{testBean.deleteWidget}">
| Normal Delete
| <f:param name="id" value="#{row.id}"/>
| </s:link>
| <a4j:commandLink
| action="#{testBean.deleteWidget}"
| ajaxSingle="true"
| reRender="testPanel">
| AJAX Delete
| <f:param name="id" value="#{row.id}"/>
