Programmatically added UIComponents forgotton
---------------------------------------------
Key: MYFACES-993
URL: http://issues.apache.org/jira/browse/MYFACES-993
Project: MyFaces
Type: Bug
Components: General
Versions: 1.1.1
Environment: tomcat 5.5.9
Reporter: Dennis Byrne
In the following JSP, the test method of the test bean creates a
HtmlOutputText, sets a unique id, sets a value, and adds it to the children
collection of the UIComponent of the div tag. However the new child component
is never rendered. The only child rendered is the first one (w/ @value = "foo"
).
<f:view>
<h:commandLink value="action" action="#{test.test}" />
<t:div binding="#{test.tag}">
<h:outputText value="foo" />
</t:div>
</f:view>
The reason why the first child (@value=foo) is always rendered has to do w/ the
fact that UIComponentTag.doEndTag ends up triggerring
HtmlTextRendererBase.renderOutputText during the render response phase. This
also explains why the programmatically added sibling is not rendered - there is
no UIComponentTag.doEndTag() .
The programmatically added UIComponent will be rendered if you wrap t:div w/ a
panelGrid or panelGroup. This is because the UIComponents for these two tags
render their own children, and MyFaces uses recursion in order to make sure the
proper encoding methods are called on *all* children.
