The template for Value Object method hashCode() calls methods for obtaining the aggregate fields. Called method returns an array (through use of toArray()) and calculating hashCode from this array results in different hash code value every time the calculation is performed. I checked this agains version 1.24 of valueobject.xdt and the problem is there too. Fix is to modify the valueobject.xdt template to generate code that calculates the hash code value directly by using the <field>, i.e. not by calling the get<field>() method. This way no temporary array is created and the hash code is same every time - unless the object has really been modified. In the original template code there is code generation for "get" and "()" in place of "XXX" below - removing these fixes hash: result = 37*result + ((this.XXX<XDtEjbValueObj:currentAggregateName/>sXX != null) ? this.XXX<XDtEjbValueObj:currentAggregateName/>sXXX.hashCode() : 0); --------------------------------------------------------------------- JIRA INFORMATION: This message is automatically generated by JIRA.
