Hi All, fairly new Metastorm developer here. I am currently working on converting a v7 solution to v9.2. We first ran the project through the newest version of the automated conversion tool, then I rewrote the various scripts that needed rewriting and tweaked everything that did not make the transition to v9 properly, to the point where everything validates fine with no errors. But when I attempt to deploy I get four "Unrecognized escape sequence" errors on "line 101" columns 89 and 93 and "line 104" columns 82 and 86, but nothing listed in the Component field for any of them, so I am not sure what line they are actually referring to.

The error itself is fairly self-explanatory (some text presumably needs to be literal-ed or escaped properly) but I have no idea where to start looking for the offending line other than searching the project for "\" and looking for something malformed, which I have actually been doing to no avail. Anyone seen this error in the designer before, or know how to figure out what code those line numbers are referring to?

Cheers,
Jeff

Well, welcome to some pain....

Personally, I would throw it at OpenText and ask them to find the source of the error. I think they should fix this issue, and have stated this several times publicly and to OpenText directly at some very high levels. Unfortunately, I have had no response. Post this issue on their forum and I'll add my support.

If you are pushed for time (when are we not?), the only way you can do it is copy it and remove pieces of it step by step until the fault goes away, then you know where the cause is. It can be extremely difficult as most components rely on other components, but it is a skill worth investing time in learning, because I don't think the problem will go away soon.

We are considering hosting a set of seminars in the US, and finding faults will be one of the main topics. The first will probably be improving performance.

Thanks for the reply Jerome, we did indeed end up "hack and slash" debugging it, and the error ended up being two table business objects that somehow had only "//" listed as their table name. I haven't had a chance to go back and figure out where this originated in the V7 code and why, but I will post a followup here when I do in case anyone runs into this issue again.

Agreed on the need for OpenText to improve the debugging process. And I'll be waiting for those seminars! By the way, I have your V7 Developer's Guide and it's been very helpful in my learning process, so cheers. Waiting for that V9 sequel! (No pun intended.)

The version 9 book(s) will be quite different. The first will be a Methodology, and I am working on this now. It seems to grow every time I look at it, but I'll try to keep it manageable so it can be finished. It is a 'real' methodology generated from real-world use and experience, both successes and failures.

The second will be a Design Guide. One of the most difficult aspects of Metastorm BPM, and one never yet addressed by any documentation of training, is how to design solutions most effectively. We have a lot of standards that we keep to, and these will be the basis of the Design Guide, with examples.
