[Trinidad] another tr:selectOneChoice + autoSubmit + PPR type question

[japher]

Hi,

I have two selectOneChoice components, and I want to have the second one invisible until the user selects a value from the first. My code looks like:

<tr:panelGroupLayout id="pgl2" partialTriggers="socPipeline">
    <tr:panelFormLayout id="pfl1">
        <tr:selectOneChoice id="socPipeline"
                      value="#{bindings.PipelineCode.inputValue}"
                      label="#{bindings.PipelineCode.label}"
                      autoSubmit="true">
            <f:selectItems value="#{bindings.PipelineCode.items}" id="si1"/>
        </tr:selectOneChoice>
        <tr:selectOneChoice id="socStatus"
                      value="#{bindings.StatusCode.inputValue}"
                      label="#{bindings.StatusCode.label}"
                      rendered="#{bindings.PipelineCode.inputValue != null}"
                      partialTriggers="socPipeline">
            <f:selectItems value="#{bindings.StatusCode.items}" id="si2"/>
        </tr:selectOneChoice>
    </tr:panelFormLayout>
</tr:panelGroupLayout>

I know that you can't ordinarily use PPR along with the rendered attribute, which is why I have added the panelGroupLayout which also has a partial trigger set.

For some reason, although the auto submit occurs, the value of #{bindings.PipelineCode.inputValue} never changes. It remains blank even when I select a value in the first select box, and so the second select box is never rendered. Does anyone know why the value is not being persisted into the model?

Maybe it is due to a submitted value being set?

Try wrapping the selectOneChoice boxes in a tr:subform and see if that
makes a difference
