RegexpURIMatcher quantifier doesn't work
I'm trying to use this regex expression in a matcher but as soon as i use
the quantifier {n} or {n,m} ^/file/id/([0-9]{3})$ Cocoon throws an
exception:
org.apache.cocoon.sitemap.PatternException: String index out of range: 21 at
org.apache.cocoon.components.treeprocessor.variables.StringTemplateParserVariableResolver.setExpression(StringTemplateParserVariableResolver.java:70)
Does this matcher not support quantifiers?

Use '\' to escape '{' and '}' braces.

Because of this i think it is trying to parse the braces as a resolvable
substitution.
....
Caused by: org.apache.cocoon.sitemap.PatternException: Mismatching braces in
expression "^file/([a-z0-9\-]{1,256)quot;
at
org.apache.cocoon.template.expression.AbstractStringTemplateParser.parseSubstitutions(AbstractStringTemplateParser.java:103)
....
How can i configure the matcher or the sitemap or whatever to not parse the
pattern attribute?

Well i have replaced the matcher with one of my own and the exception is
still being thrown. It looks like is the sitemap parser which is throwing
the exception as soon as i include the "{ }" characters in the pattern
attribute. I have tested this:
1.- Adding " } " alone throws: org.apache.cocoon.sitemap.PatternException:
Mismatching braces in expression "^file/([a-z0-9\-]{)$
2.- Adding " { " alone everything works, regex do not match of course.
3.- Adding " { } " throws: index out of range exception.
4.- Adding " {2} " throws: index out of range exception.
Any clues?
