If you mean "where is the initialisation of simpleMap e.g. simpleMap=new

That can be a problem, generics are erased during compilation and Ognl

prepare converter for it?

settings is a SettingList which is just an extended ArrayList.
The rendered source looks like:
Currently there is only one Setting, but adding another arbitrary entry does
come up with settings[1].value, etc.

Okay, I changed it back to settings[0] type syntax (I had tried it before and
it didn't work), so now I have this:
your syntax for the field name should be
...name = "settings[]" rather than name = "settings()"
Also, I think your action expects to build a List of Settings rather than
Map of settings. If that is the case then you don't want to use key values
in settings[ASDF1-123AS-123SA-123] you want to us

hi,
A simple workaround would be defining the bean property as String type
rather than as the actual enum.
Then use the two enum type built in operations "name()" and "valueOf()"
to implement the getter and setter respectively.
If there is actually an elegant way to do it, I would also be i

As a sanity check perhaps you could try using a Map. I know you can get a Set
view of a Map, so perhaps this is an alternative solution (I'm not so sure
about going the other direction, however).
This would at least narrow down the problem
I'm assuming you can't change them because someone else created them? There
are still ways you can deal with the beans with sets..
1) Wrap them using the Adapter pattern. However if they are already coming
back nested and you can used the adapters/wrappers in the business layer you
could also..
2)
I know. Unfortunately i can't change my business beans anymore :-( Anyway,
any other ideas? I am trying now with a EoActivities-conversion.properties
file, containing
Element_eoActivity = com.datamat.care.bean.EoActivity
Element_eoUser = com.datamat.care.bean.EoUser

At least in Struts1.1, If I'm not mistaken, you aren't going to be able to
use indexed properties like you are to set items in a Set. If you use Lists
it would be much easier to accomplish the nested collection population.
