[Trinidad] Is it legitimate to modify the component tree during a PPR request cycle?

[Zarick Lau]

Dear users and developers,

Is it legitimate to modify the component tree during a PPR request cycle?
This looks trivial, but I failed to get it work, am I missed anything?

The following code are executed during valueChangeListener.
        CoreInputText text = new CoreInputText();
        text.setSimple(true);
        text.setImmediate(true);
        getFileControlComponent().getChildren().add(text);
        RequestContext rc = RequestContext.getCurrentInstance();
        rc.addPartialTarget(getFileControlComponent());

Where getFileControlComponent() return a panelGroupLayout component.


The following is the corresponding tag snippets:
<tr:panelGroupLayout binding="#{documentPanel.fileControlComponent}">
    <tr:inputFile
            valueChangeListener="#{documentPanel.onFileUpload}"
            simple="true"
            immediate="true"
            />
</tr:panelGroupLayout>
<tr:commandLink text="Upload Now!"
    id="upload"
    immediate="true"
    partialSubmit="true"
    actionListener="#{documentPanel.upload}"/>

The following is the environment:
 JSR RI 1.2_04-b16-p02
 Facelets 1.1.12
 Trinidad 1.2.1

Thanks!

Best regards,
Zarick
