I tried to upgrade from Castor 0.9.5.2 to 0.9.5.3 today, but my code would
no longer compile because the code that was generated from my schema is
different. My (slightly watered-down) schema is given below. The gist of it
is as follows:
1) I have a main element called "table" that has a list of "mapped-field"
elements and a list of "derived-field" elements.
2) "mapped-field" and "derived-field" are defined as extensions of a common
element ("field") which defines some common attributes.
3) My intention is to generate a base class "Field" and two subclasses
"MappedField" and "DerivedField" that extend "Field".
What I am finding is that the Field, MappedField, and DerivedField classes
are being generated correctly, but the generated accessor methods in the
Table class end up being defined as:
Object[] getMappedField() and Object[] getDerivedField()
instead of
MappedField[] getMappedField() and DerivedField[] getDerivedField()
Trying to cast the results of these methods to MappedField[] or
DerivedField[] generates a ClassCastException. I can't figure out whether
this change is intentional (i.e. some change in functionality with the new
version) or a bug. Any advice would be appreciated.
