[errai-dev] Dynamic adding of children to a template in Errai-UI

[Lincoln Baxter, III]

Hey Daniel,

I have a few thoughts about this. I think maybe the best solution is to
create a few convenience classes in Errai UI that handle wrapping Panels
for use in other objects, but yes, I did find something that I think will
help.

Could you just do something like this?

@DataField
> private HTMLPanel list = new HTMLPanel("ul", "");
>
> ...
> list.add(new ListItem());
>

Also, could I ask you to put this into a JIRA so the entire team can see
this and keep track of ideas?

https://issues.jboss.org/browse/ERRAI

I think the problem you are running in to is that you want to template an
LI, but you don't want to actually implement an LI widget? I think I'm
still missing a few details, sorry for being obtuse.

Also, perhaps you could ask in the #errai channel on IRC.freenode.net, I am
trying to get the team to monitor the dev list more, but for now, most
discussion happens on IRC. If nothing else, we can discuss on JIRA.
