Yes, this is it. I have a component which is looped over.

1) initially I tried to simply use MyObject instance passed as a
parameter
inside AjaxFormLoop;
This won't work if you don't pass it as the context of Submit. Submit
passes to the event handler the context it receives, without any guessing.
2) then, I tried to pass this instance as context., getting the
same results
This will only work if you contribute a ValueEncoder for MyObject.
3) finally, I tried to use obj.id as a context parameter instead - again,
onSelectedFromSubmitControl was being called with context parameter
belonging to the last iteration of the outside loop
Outside loop? So there's nested loops?
At this point I gave up and solved the problem otherwise, without having
to
rely on t:submit context.
I guess I understand your point, but t:submit does not encode context
inside submission URL (unlike t:actionlink or t:eventlink). Probably
that's
the reason why my initial approach didn't work.
If you're correct, and I haven't done any testing to know if you do, then
it's a bug. Have you tried, in a separate page, something similar but
simple enough to reproduce the problem?
In fact, when t:submit is being used inside a loop and IS NOT ENCLOSED BY
OTHER COMPONENT, this scheme works.
It shouldn't make any difference (not being enclosed by other component).
It may indicate an error in your part. It may be a bug in Submit. Looking
at the source (5.1, unfortunately I'm working on projects still using that
version), it seems to be a problem in Submit, but I won't be sure until I
run or see an example.
For example, in the same application I have constructs like:
<t:ajaxformloop>
<t:submit t:id="someId" p:context="loopContext"/>
</t:ajaxformloop>
I'm not sure the p: prefix is actually valid here. t: is the one usually
used for non-block parameters, while p: is used for block ones.
