I've scoured the forum and docs trying to figure this out and have been
unsuccessfull, so hopefully someone can steer me in the right direction.
I have a page that displays a set of dataTable elements. The scenario is that
I have a bunch of objects that can be categorized. The list of categories is
dynamic. On the page, I am iterating over each category (using ui:repeat) and
displaying a dataTable for each category. The dataTable snippet currently
looks like:
| <ui:repeat value="#{allCategories}" var="category">
| <rich:dataTable width="100%" var="record"
value="#{calculationManager.findCalculations(category.id)}">
| <rich:column>
| <h:outputText value="#{record.calculation)}"/>
| </rich:column>
| </rich:dataTable>
| </ui:repeat>
|
The allCategories property is backed by a DataModel, this is fine. The
dataTables are being populated by a bean (referenced by calculationManager)
that contains the following:
| public List<FinancialCalculation> findCalculations(int categoryId) {
| return (List <FinancialCalculation>)em.createQuery("select f from
FinancialCalculation f where category_id=:c")
| .setParameter("c", categoryId)
| .getResultList();
| }
|
This is displaying as I want. However, my next step is that each item in each
table needs to be clickable (it will take the user to a details page).
There are two options that I've thought of. First, I can use a commandLink and
pass an id of the selected item through it, then look up the object in the
method that is called. I haven't done it, but can't think of why it wouldn't
work. It just doesn't feel "correct".
The second was to switch to using a DataModel to back each table and use the
DataModelSelection functionality. This is what I think I should be doing. The
problem is, I don't know how to create the DataModel using a factory method
that needs to take a parameter (ie, make the findCalculations method above be a
factory). Alternatively, I could remove the method parameters and add an
injected property:
@In private Integer categoryId
But then I don't know how to have the proper value injected for each of the
dataTables.
Did I explain that clearly? If so, any suggestions?
Thanks!
Matt
