Hi Heiko, are you using the latest snapshot from SVN? Since the last release there are several fixes and enhancements to the escaping mechanism. Please use the latest version from the trunk if you don't have it and let me know if this still does not work as expected. (A new release will be available soon).
There is no kind of semantic analysis in the framework. It is just the parser and any error handling except basic syntax errors is up to you. Hope this helps....

For example, the string 'pa\%ern' which according to the CMIS spec is supposed to look for the value 'pa%ern' is acknowledged with the two messages "mismatched character '%' expecting set null" and "mismatched character '<EOF>' expecting '''" and a CmisInvalidArgumentException. Sounds like a lexical analysis problem to me. - Is there semantic analysis built in? For example, the = ANY operator is not possible for single-valued properties, and, vice versa the simple = operator is not allowed for multi-valued properties. However, no error is announced when parsing this kind of statement. Would be great if you could tell us whether these are known limitations at this time but are worked on, or whether we're making any mistakes.
