sort entries by the selected tag

[Anton Pussep <an...@pussep.de>]

Hello,

I would like to sort the menu created by the selected tag. So far I just
pass a TreeMap where the entries are sorted already. However, I think
that the View should decide whether to sort or not to sort, but I could
not find a way to force the selected tag to sort. Is there anything you
can recommend?

<s:form action="DeleteUser">
    <s:select
        list="idToNameMapping"
        name="userId"
        emptyOption="false" />
    <s:submit />
</s:form>

Thanks and best regards,
Anton

LinkedHashMap.

I think you're right, the View should not be responsible for sorting.
But now I would like to sort by values and I could not find any Map that
is capable of doing so. Do you have any suggestion? Or probably you had
to solve this problem already, then I would love to hear how you did it.

It does not necessarily have to be a sorting map, it could be also one
that just guarantees that its elements keep the order in that they have
been added.

Best,
Anton

I've always put sorting as part of the action by determining the sort order
creating an appropriate Comparator implementation and using it in the
constructor for the TreeMap.

I've done this because imho your view should just be about presentation, and
the logic for determining and implementing your sort should be in your
action.
