I'm running into a bit of a snag with the client side validation facilities in Monorail using ValidateRegEx. It seems that when it generates the JS for the client-side validation, it fails to correctly escape "\" characters, thus leading to an invalid JS regex pattern.

Here's an example; let's say I have this pattern:

[ValidateRegExp(@"\+\d{1,3} \(\d+\) \d+")]

This seems to get translated into the following piece of JS:

{ pattern : new RegExp("\+\d{1,3} \(\d+\) \d+") }

Since this is a string and not a regex pattern (i.e /.../). the single \ gets ignored and this the expression is interpreted as:

+d{1,3} (d+) d+

which is obviously not what I wanted... The right expression is, of course, perfectly valid JS, so it should really have been converted as:

new RegExp("\\+\\d{1,3} \\(\\d+\\) \\d+")

I'm using a fairly recent build, and didn't see anything relevant in JIRA, either. Any ideas?

When you say fairly recent you mean a last week's? If the latest build doesnt work, can you please fill a jira issue with some code that reproduces it? I shall check it shortly. Thanks

Hammett,

It's fairly recent. I think I downloaded one of yesterday's builds. I'll gladly jira it; but just to make sure, do you want it registered under the validator component or under monorail?

OK, I went ahead and got the source from SVN and looked at it myself. Indeed, the problem is as I described. For the Prototypes validator, it can be fixed by changing line 212 of PrototypeWebValidator.cs to:

config.AddCustomRule(rule, violationMessage, "pattern : new RegExp(\"" + regExp.Replace(@"\", @"\\") + "\")");

I don't know about the ZebdaWebValidator as I haven't used it.
