nested controls

[mr. App]

I'm trying to do the following:
<ctl:Control1 id=a1 runat=server>
<ctl:Control2 id=a2 runat=server Text="temp" />
</ctl:Control1>

Both controls are simple custom web controls. The problem is that the inner
control is not being rendered. I read in MSDN that I have to add
[PersistChildren(true), ParseChildren(false)] but is also didn't help.

Thanks.
