If the cart is built on MG 1 or MG 2, then it will work on MG3. See the following articles on upgrading to new versions:
- http://docs.model-glue.com/wiki/UpgradingModelGlue/UpgradingFromModelGlue1#UpgradingFromModel-Glue1 - http://docs.model-glue.com/wiki/UpgradingModelGlue/UpgradingFromModelGlue2#UpgradingFromModel-Glue2 There are really only two things you may have to look into. ColdFusion 9 introduced the *trace()* method. This conflicts with the MG trace method on EventContext.cfc. You will need to update your codebase and change all instances of *trace()* to *addTraceStatement(). *MG3 is CF9 ready, so this has been done. MG 2 was built before CF9, so most copies in existence use trace() though the last release of MG2 is fully compliant with CF9 and any developer code relying on trace will need to update to addTraceStatement(). Just a simple method name change, the method signature is still the same. The other thing you may have to do is upgrade ColdSpring to the latest version 1.2. This is a no-conflict change and won't affect old code built on ColdSpring 1 or prior versions. So it would seem as if you can upgrade to MG3 and not worry about keeping two versions running at the same time, right? DW On Fri, Jan 15, 2010 at 7:37 AM, Bud <[email protected]> wrote: > Hi Dan.
