AEM 6.2 Predicate fn:lowercase generate special characters

[Unnikrishnankv]

 final Predicate authorNamePredicate = new Predicate("@authorName", "property");
            authorNamePredicate.set(JcrPropertyPredicateEvaluator.OPERATION, JcrPropertyPredicateEvaluator.OP_LIKE);
            authorNamePredicate.set(QueryUtils.PROPERTY, "@fn:lower-case("+CharacterConstants.SLASH +JcrConstants.JCR_CONTENT + CharacterConstants.SLASH + "authorName)");
            authorNamePredicate.set(QueryUtils.VALUE, authorName.toLowerCase());
            group.add(authorNamePredicate);

This is the code used to generate xpath query that is added below

=/jcr:root/content/geo//*[@jcr:primaryType = 'cq:Page' and not(jcr:content/@hideInNav) and jcr:content/@jcr:title != 'Master Article' and jcr:like(fn:lower-case_x0028_/jcr:content/@authorName_x0029_, 'soumik dey')]/rep:excerpt(.) order by jcr:content/@cq:lastModified descending

special characters generating area are highlighted in bold. Could you please help me to sort out this.

Thanks!,

Hi 

Please have a look at this forum thread:-

//  we never officially supported functions.  Hence not a bug. You have to file enhancement request to support xpath function. it is a known problem with the OAK repository

Please create a day care ticket for this.

Reference post telling about toupper/toLower in AEM :- http://www.wemblog.com/2013/04/how-to-create-custom-query-predicate-in.html

// You need to create a create custom query predicate.

I hope this would help you.
