Yup, that's the only one. It's old, it's a bit buggy but works for the most part.

(coming from the guy that created fmsguru.com)

Believe me, if there was another better one I would be pushing that out instead.

To note, Dreamweaver has the ability to provide code hinting if I remember correctly but I'm perpetually disappointed in the FMS team for not providing even ONE item that helps in the development of server side coding for FMS. They have never provided anything and it's been up to the good will of developers for the platform to put together tools. As it is now, you'll probably never see anything better as most people (that I know of) have moved away from FMS, partially for this reason despite multiple requests that Adobe do something. Not to insult the FMS team, as they do what they have to do to pull in the paycheck, and the bean counters provide that and seem to be making most of the decisions.

ok. rant all done now

I would never mislead my clients. If I thought that the lawsuit had any credibility then rest assured I would point my clients elsewhere. That's just not the case though.

The more people that can develop for FMS the better. It creates work and demand because people will see that others are actually using the software. By providing nothing you make it more difficult to get into, increasing learning time, increasing cost and so on and so forth. It's not the norm and doesn't appeal to most developers.

At least their documentation is good though.

No worries, definitely stand up for what you believe in. There's nothing wrong with being honest with clients up front and giving them the whole picture.
