Get a list of AIF exceptions caused during a single update (Dynamics AX 2009)

Hi

I am using the example from this site (http://axdevnotes.blogspot.co.uk/2011_06_01_archive.html) to get the last AIF error message - but how do I get all the error message associated with an update for example, where I set two entity fields to invalid values - I am able to get the first exception but not the second.

I do see both exceptions in the Exceptions log - but only able to retrieve one error message using the code (link) above?
