Adding block to block container - disappears after adding new block

Vote:
 

I have a block that contains a block.  When I add a new block to this block container, it doesn't show and therefore can't be published.

The first class below is my block container.  Second is the block that the container holds.  Third is the page.  

I've basically copied code that a previous developer used to do something similar.  What am I missing?

Thanks,

Tim

When I do get the Publish button to show, I get a could not save property error or nothing happens.

I also verified that the properties for each Block Type and Page Type are not missing by looking at the respective properties in the Admin tab of CMS.

Code looks fine to me. Can you try removing the AllowedTypes attribute?

AllowedTypes(typeof(SelectableColorsBlock))

And if it works then try adding back or rename one of the block.
