Have you ever burned your hands by some new and immature technology? [closed]

Question

I can write a pretty good Java Applet. All technologies will fall by the wayside eventually, but this one had a very sharp rise and fall.

I'm currently in the process of getting burned by Microsoft Office Word 2007's CustomXML support.

CustomXML allows the document to have custom defined elements that can model business data etc. For example, you could define an XSD with your custom elements, associate it with a docx file, then generate the placeholders as CustomXML tags and navigate/modify the documents using C# (or other .NET languages) and the OpenXML SDK. The benefit of OpenXML is that it decouples the need to have Office installed on a server machine for automation purposes and is an alternative to purchasing 3rd party libraries.

In short there was a lawsuit regarding Word 2007's ability to open documents with custom defined XML. From this article:

On August 11th, the company received an Office Word sales injunction ...

"This injunction applies only to copies of Microsoft Word 2007 and Microsoft Office 2007 sold in the U.S. on or after the injunction date of January 11, 2010. Copies of these products sold before this date are not affected."

Microsoft's response is to remove support for CustomXML from future versions of Word and is releasing a patch that would entirely remove this capability. Here is the link to the official update. According to this Microsoft OEM Partner Center site:

The following patch is required for the United States. The patch will work with all Office 2007 languages.

After this patch is installed, Word will no longer read the Custom XML elements contained within DOCX, DOCM, or XML files. These files will continue to open, but any Custom XML elements will be removed. The ability to handle custom XML markup is typically used in association with automated server based processing of Word documents. Custom XML is not typically used by most end users of Word.

I imagine a tiny percentage of end users and developers make use of it, so I consider that last sentence to be accurate. The problem is there's currently no word (no pun intended) on how to move forward for projects that did utilize this technology. CustomXML is the cornerstone of a large project I'm currently working on. The impact of this decision is not positive and it effectively prevents any forward compatibility as there's no equivalent alternative approach that maintains the structure that CustomXML provided.

Some of my coworkers and I have a wealth of knowledge on the topic... I guess it's good we didn't get around to writing blog posts about it as we had planned :) We've accomplished some pretty impressive feats with this and the VSTO, but this news is disappointing.

If anyone's interested in this topic here are some articles to check out:

EDIT: added link to the official update.

Several years ago, we made heavy use of the new SQL Server 2005 feature called Notification Services. To our dismay, that has been discontinued in SQL Server 2008. This was a serious problem, caused the software architect to question all new Microsoft technologies.

Here's some detail and some more and some more

There have also been issues with Microsoft's Entity Framework.

Anybody else remember OpenDoc, Apple's idea for how all new Mac applications would be written? Didn't think so.
