Using JSF 2.0, I need to display a table wherein each row contains a link which opens a popup. I have two models: A
which has id
and List<B>
properties and B
which has id
and name
properties. In my backing bean, I have a List<A>
property. In my view, I am using <ui:repeat>
to iterate over List<A>
.
The requirement is, depending on the row that the user clicks, the corresponding List<B>
of A
needs to be displayed. However, the <ui:repeat>
does not accept a nested list to be assigned in the var
attribute. Hence, I need to do a lot of workarounds which is not efficient.
How do I efficiently solve this problem?
What you need is to nest another <ui:repeat>
tag in your outer iteration:
<ui:repeat value="#{bean.listOfA}" var="a">
...
<ui:repeat value="#{a.listOfB}" var="b">
...
</ui:repeat>
</ui:repeat>
The only thing left that is worth noting is that nested <ui:repeat>
tags used to have problems with state management until Mojarra 2.1.15 version (details in jsf listener not called inside nested ui:repeat and in many not so recent questions and their answers), which could result in action listeners not called, etc. but if you're currently on the latest Mojarra JSF implementation - just skip this part altogether.
