I'm getting a Invalid Cast Exception when trying to build a DDT Install package.   I have a table which has some NULL fields and the Packager errors out.

Any Ideas,  The data has to have a null in this particular column.

This is not supported at the moment.  This is on an enhancement list but has not been implemented into the Deployment Data yet.  I am not sure if this will make it into the next point release or not, when we initially looked at this we came to the conclusion that this could require a relative significant change to the packaging of the data.  Though we will be looking at this request again before the next point release to make a more exact ruling as to whether it will be included in that build or not.
