h:dataTable, HashMap, and List

[jtsimikas]

If I've defined a List within a HashMap
(which I want to use in h:dataTable component)

See below:

private Map <String , List<ScsMessageBlock> > scsMessageBlocks;

Is it possible to reference the List in h:dataTable component?


Then would this work ?

<h:dataTable value="#{scsMessageBlocks['SomeKey']}" var="msg"
 styleClass="width100" >

..
</h:dataTable>

The above code generates the following error even though that key does exist in the HashMap and a List with rows has been allocated.

java.lang.IllegalArgumentException: row is unavailable

Stack trace?
