Hi guys,

I am getting NPE when generating SQL in EntityModeler.

java.lang.RuntimeException: Failed to generate SQL.

I am guessing that the NPE would seem to indicate that I have a missing external type field on one of the attributes, but as you can see in this pic, all external types are resolved to prototypes. By any chance would using uncommon INT types such as TINYINT, SMALLINT, MEDIUMINT be causing this problem? ... or might this be something else? WO version is 5.3.3, WOlips 3.5.latest.

Any ideas?
