Issues Persisting Design time changes to page source

[jebecker]

I have a Control which I'm designing the LiteGrid which has two properties
"Columns" and "Actions". These properties are in turn Collections of
sub-items.

in the end the aspx source should look like:
<pr:LiteGrid runat="server" id="lgDemo">
<Columns>
<pr:Column ... />
<pr:Column ... />
</Columns>
<Actions>
<pr:Action ... />
<pr:Action ... />
</Actions>
</pr:LiteGrid>

However when I modify these collections via the designer, the changes show
up in the design-time rendering but fail to get persisted to the aspx page.
How can I force VS.Net 2k5 to persist changes back to the source?

And now for some unknown reason it has started working. God only knows why.
