Alternate title: "XML is an unforgiving master"
To whom may have been affected: please accept my apologies. As an excuse, all I can offer is that I put the instructions together by hand in a hurried fashion (I was quite excited), and though I double-checked the instructions, I failed to double-check the schema.
I was floored to have received a very flattering review from Matt Wittemann, whose blog I have visited several times for solutions to my own CRM deployment. There was never a doubt in my mind about the need for such a grid-editing utility within CRM, and with as many other solutions that were available to achieve it I never suspected mine would be popular outside of a tight circle of enthusiasts (especially considering some of the limitations present in this early version of the project). Matt's acknowledgments and praise were very encouraging.
Matt also touched upon idea that the code could be deployed to CRM Online, where no alternative is available. I find this irreversibly tantalizing. Personally, I have no access or ability to operate my code in a CRM Online environment, so I hope that you, the community, will help me test its capabilities in that area.
