T5.2.4 - Unexpected illegal argument exception: Input string
'${context:css' is not valid
Hi,
Here is an exception caught by my Exception Report Handler.
However, I cannot remember seeing the actual exception happened.
(And of course, I'm not able to make it happen.)
Is there someone able to give me some explanations and solutions to avoid
it?
java.lang.IllegalArgumentException:
Input string '${context:css' is not valid; the '$' character at position 1
should be followed by another '$' or a four digit hex number (a unicode
value).

Obviously, '${context:css' is in some of my .TML files, most of the time to
call images.

I see it too. Haven't tracked it down though. I'd think the only clientside
indicator of the problem would be a missing image.

That's what I changed mine to, I found something commented with .
There definitely aren't bots on my staging server though. Just IE
browsers...

Better yet, use the <t:remove> directive, rather than a HTML comment,
to (temporarily) remove a stretch of template content.

Hi,
we have seen this also and more than likely it's not the browsers to blame,
but the search bots. (At least on open networks.)
I once took a look at our apache logs and discovered that there are many
bots out there that do not respect any comments on pages at all, but rather
seem to get everything that has src, href or anything that vaguely resembles
a url. (Even those that are not in a src or href context.)
The bot probably sees only text that it parses with regexps etc. The
templates should not contain any comments - those take unneccessary space
and bloats page in addition to this. ;)
Can we instruct T5 to strip comments before sending content out?

I've got it!
In one of my .TML files I put this comment:
*<!-- <img src=${context:css/img/blabla.png} /> -->*
My guess is some web browsers try to access the image, even if it is a
comment.
And, there is the exception.
I removed this comment from my .TML file.
I keep you informed if it happens again.

This happens randomly for me. Exact same page/template, suddenly decide to
error 1 time out of 100. My guess is it sometimes doesn't process the
expansions.

Somehow a request to a page had "${context:css" in the URL. By any chance
are your passing this string from a page or component class to the
template? Using ${} expansions in templates wouldn't cause this kind of
error.
