Alan,
I concur with Jacopo and Tim that major changes are rare. Rarer still, if not entirely
non-existent, are changes that break your existing functionalities (eg extending or truncating
primary keys).
The OFBiz framework is such that you can easily extend many things, especially(!) the entities.
Use the "<extend-entity>" in your entitymodel.xml for this.
In short, you can do your customizations _apart_ _from_ the OFBiz codes. You can then pull down
updates from the OFBiz trunk without affecting (or at least without overwriting) your
customizations, leaving them intact through many updates from the trunk. Sorry, double emphasis
there, was afraid you'd miss that point. :P
It is possible to update from OFBiz trunk while leaving your customizations intact.
