Whenever we remove relationships or rename the variables which constitute an old
existing relationship, the old variables are nether removed or renamed instead
new variables are created with new names. Under similar circumstances when
variable names in multiple relationships clash i.e. when two variables in the
same class have same name no error is shown in the relationship editor instead
the original methods for the variable remain abstract and a new set of methods
non-abstract are created for the repeat. This is clearly a lack of
synchronization between the source code and the ejb-jar.xml file.
