Ok I have this annoying problem with NullPointerException inside a size() method that is called on Set object. Method looks like this (after serveral mutations...):

Asset.java
Code:

    private Set attributeValues;

    public Set getAttributeValues() {

        TreeSet sorted = new TreeSet();

//        log.debug("##" + attributeValues);
        if (attributeValues == null) {
            log.debug("### attributeValues NULL");
        }
       
        if (this.attributeValues != null){
            if (!this.attributeValues.isEmpty()) {
                sorted.addAll(this.attributeValues);
            }
        }

        return sorted;

    }

    public void setAttributeValues(Set attributeValues) {
        this.attributeValues = attributeValues;

    }

What are you trying to do?

Code:
set name="AttributeValues" inverse="true" lazy="true" where="is_current='true'">
            <key column="asset_id"/>
            <one-to-many class="AttributeValue"/>
        </set>


just replace the crap in the getter with a simple
Code:
return attributeValues;
whatever you are trying to do doesn't belong there.
