IllegalStateException at org.apache.catalina.connector.ResponseFacade.sendRedirect(ResponseFacade.j

[Volodymyr Levytskyi]

Hello!

I have commandLink within the form:

<h:commandLink action="#{forumBacking.goToTopicPage}" value="#{topic.name}" styleClass="topicNameLink" />

When i click it simple method is executed:

public String goToTopicPage() {
		Integer topicId = getTopicItems().getRowData().getId();
		System.out.println("ForumBacking.gotoTopicPage.topicId=" + topicId);
		return ("/topic.xhtml?faces-redirect=true&topicId=" + topicId);
	}

This method leads to below exception:

I know that this method causes exception because phaselistener shows that invoke_application phase ended before exception and does not show that render_response phase started.

Thank you for any ideas!

Normally, I'd say that it's because you have ".xhtml" in your navigation string. But I think you previously said you are set up to accept ".xhtml" as a JSF URL extension. I still have misgivings about that, however.

Most likely your problem is because you are attempting to parameterise the navigation URL. You cannot do that. Action methods can only return simple navigation IDs or URLs without parameters.

A better approach would be to inject the backing bean for topicPage into the action method's backing bean as a managed property and use its "setTopicId" method to inject the topic directly into the target backing bean.
