Subject [jira] [Created] (MYFACES-3191) Handing exception (in exception handler) from render response phase with forward/redirect is inconsistent

Handing exception (in exception handler) from render response phase with forward/redirect is
inconsistent
---------------------------------------------------------------------------------------------------------

                 Key: MYFACES-3191
                 URL: https://issues.apache.org/jira/browse/MYFACES-3191
             Project: MyFaces Core
          Issue Type: Sub-task
    Affects Versions: 2.1.2-SNAPSHOT
         Environment: myfaces trunk
            Reporter: Martin Kočí


View.xhtml snippet:
<h:commandButton value="Submit">
                <f:setPropertyActionListener value="#{true}" target="#{bean.rendered}"
/>
                <f:ajax render="outputText" />
</h:commandButton>
<h:outputText rendered="#{bean.rendered}" id="outputText" value="#{bean.value}" />

Bean.java snippet:
public Object getValue() {
		throw new NullPointerException();
}

Custom exception handler code:
			if (PhaseId.RENDER_RESPONSE.equals(currentPhaseId)) {
				try {
					nav.handleNavigation(facesContext, null, "/ErrorPage.xhtml?faces-redirect=true");
				} finally {
					i.remove();
				}
			}
Modify view and exception handler to achieve following combinations (HTML request = comment
out f:ajax, forward = remove ?faces-redirect=true)

1) HTML request  + forward: nothing in log, and malformed output is produced (no closing tags
for  </body> etc.)

2) HTML request + redirect: OK , redirect to ErrorPage.xhtml is done

3) AJAX request + forward: exception in log, bud no forward to ErrorPage performed

4) AJAX request + redirect: exception in log, malformed XML produced (<?xml and <partial-response
2x in output) , no redirect performed
