Jdev 11g, Passing data between pages using data control

Question

Hi,
I'm fairly new to Jdev, J2EE, and ADF. I created a project using the tutorial "Build a Web Application with JDeveloper 11g Using EJB, JPA, and JavaServer Faces" (found here: http://www.oracle.com/technology/obe/obe11jdev/11/ejb/ejb.html).
Data model part seems to work fine. I am able to connect to the database and print out a record using the sample client.
Now I'm trying to build the web front end for it. I started using a data control and ADF to make the components. I built a search page by dragging and dropping my method from the data control onto a form. I set the action on the form to go to a detail page which I put a database node from my table product_group. My thinking was the user would put in the id and then be taken to the next page that has the detail on it.
When I ran the page though the search page seemed to execute fine but the detail page came up blank. There were no runtime errors. I think data is not being passed to the next page.
This is the code for the form on the search page:
<af:form>
<af:panelFormLayout>
<af:inputText value="#{bindings.p_id.inputValue}"
label="#{bindings.p_id.hints.label}"
required="#{bindings.p_id.hints.mandatory}"
columns="#{bindings.p_id.hints.displayWidth}"
maximumLength="#{bindings.p_id.hints.precision}"
shortDesc="#{bindings.p_id.hints.tooltip}">
<f:validator binding="#{bindings.p_id.validator}"/>
<af:convertNumber type="number"/>
</af:inputText>
<af:commandButton actionListener="#{bindings.queryProdGroupFindByID.execute}"
text="Search ID"
disabled="#{!bindings.queryProdGrouptestFindByID.enabled}"
action="search"/>
</af:panelFormLayout>
</af:form>
This is the detail page:
<af:form>
<af:panelFormLayout>
<af:panelLabelAndMessage label="#{bindings.description.hints.label}">
<af:outputText value="#{bindings.description.inputValue}"/>
</af:panelLabelAndMessage>
<af:panelLabelAndMessage label="#{bindings.id.hints.label}">
<af:outputText value="#{bindings.id.inputValue}">
<af:convertNumber groupingUsed="false"
pattern="#{bindings.id.format}"/>
</af:outputText>
</af:panelLabelAndMessage>
<af:panelLabelAndMessage label="#{bindings.status.hints.label}">
<af:outputText value="#{bindings.status.inputValue}"/>
</af:panelLabelAndMessage>
<af:panelLabelAndMessage label="#{bindings.storeId.hints.label}">
<af:outputText value="#{bindings.storeId.inputValue}"/>
</af:panelLabelAndMessage>
<af:panelLabelAndMessage label="#{bindings.type.hints.label}">
<af:outputText value="#{bindings.type.inputValue}">
<af:convertNumber groupingUsed="false"
pattern="#{bindings.type.format}"/>
</af:outputText>
</af:panelLabelAndMessage>
</af:panelFormLayout>
</af:form>
I guess what I'm asking is how does data get passed to the detail page using a data control? Also if anyone has an online book about data controls and how they work I'd appreciate that too. Too much magic going on.
Thanks in advance.

Answer 1

I went to the bindings tab for my search.jspx page and found in the 'executables' table queryProdGroupFindByIDIterator. I looked in the properties for that and 'CacheResults' is set to '<default>true'. Next page still looks blank. I changed it to straight up 'true' and that didn't work either.
If I'm in the right place I guess it must be something else?
