I am trying to display a HashMap in a datatable where the values for each key is an ArrayList e.g.

Now I have a Datatable with two columns. First column shows the key and the second column I again have
a datatable to show the ArrayList. So I will have one row with a key and the values again shown in a
datatable. So far I no luck and need some help on how to achieve this. Here is the index2.jsp code I have:

And here is the backing bean Index2.java I have:

Now when I run this application the keys are shown in the respective column but values are coming up as

[AA2, BB2, CC2] in one row rather in a separate Row as I am using a Datatable inside UIColumn to show the values.

Here is what I see in the output:

As above output is not correct as it shows both list values in front of each key rather than what those
keys are tied to. I wanted the following output:

So I can do sorting pagination on the values datatable. But currently the output is not shown correctly. Any help
is really appreciated. My hashmap will be populated dynamically so wants to show the key and values in separate column
but also need to show the values in an embedded datatable as the list can be huge.

I know this reply is too late but I've just saw your post today and I hope that my reply will help.

You need only to do the following

<hutputText id="out3" value="#{var2.value}"/> in the second dataTable to
<hutputText id="out3"
Don't get me started about those stupid light bulbs.
