In jcr every node has a node-type (value of "jcr:primaryType"). Most node-types define a schema of properties that are allowed on that node and that has to be defined in the schema. If you try to add and persist (commit) a property that is not defined, you get exactly this ConstraintViolationException.So here's what likely happened: You've tried to create and store a property on a node that has a strict schema, where that is not allowed.

Javscript logic is wrong -It should be like$("#moreli").click(function() { $( this ).css("display", "none"); $( this ).sinbling("#lessli").css("display", "block"); $( this ).sinbling(".hide-more").css("display", "block"); }); Above cpde is just for reference, please implement logic based on current(this) object to deal with individual instance.
