I came across a minor limitation in 2010 today that is worth keeping in the back of your mind.

 

Scenario

You create a SharePoint list that has a column type of 'Managed Metadata'.

You then decide you want to customise the SharePoint list form using InfoPath.

 

 

Problem

When opening the list form in InfoPath you receive the following warning:

 

On opening the form in design mode, the 'Managed Metadata' field is not available on the form canvas and cannot be added

 

On publishing the form and then creating a new item in the list the managed metadata field is not available to complete

 

If the 'Managed Metadata' field is mandatory – on creating a new item in the list you receive the error "The following required fields are missing from the form".

 

Moral of the story – Managed Metadata field types and InfoPath forms don't play nicely together 
