I'm trying to implement a simple table for selecting a table row and editing
the selected row in a form in a different way than I did it before. Table
and form are rendered through the same JSP (see below) such that no
navigation rules are required.
This does not behave as expected-> when a row is selected, its data is shown
in the form. After returning back to the table and selecting a different
row, the form shows the same row data as before BUT NOT the data for the new
selection.
So I assume there is a problem with the component state??? I have modified
the implementation such that the form is implemented by a different JSP and
a navigation rule navigates to this form JSP as #{listController.select} is
invoked! ->> It works!
Background info for the used managed beans: #{listController.select} is
responsible for getting the selected row object and injecting it into
#{formController.entity}. The listController is a request scope bean whereas
the formController is a session scope bean.
<tr:form>
<tr:table value="#{listController.model}" var="object"
rendered="#{formController.entity==null}">
<tr:column>
<tr:commandLink action="#{listController.select}">
<tr:outputText value="#{object.type}" />
</tr:commandLink>
</tr:column>
</tr:table>
<tr:panelFormLayout rendered="#{formController.entity!=null}">
<tr:outputLabel for="typeInput" value="Type" />
<tr:inputText id="typeInput"
value="#{formController.entity.type}" />
<tr:commandButton text="OK" action="#{formController.store}"
id="okButton"
/>
<tr:commandButton text="CANCEL"
action="#{formController.cancel}"
immediate="true" />
</tr:panelFormLayout>
</tr:form>
listController.select is implemented like shown below
public String select() {
setSelectedEntity((T) getDataModel().getRowData());// this
injects the
selected object into the form controller
return OUTCOME_SELECT;
}
The JSPs have been implemented using Trinidad, my assumption is that this is
not a Trinidad issue but rather a general JSF life cycle issue!
