Modified: src/antidote/org/apache/tools/ant/gui/customizer
DynamicCustomizer.java
Log:
Changed mechanism by which the PropertyEditor editor is instantiated so that
it
uses whatever class is retured by BeanDescriptor.getCustomizerClass() rather
than assuming DynamicCustomizer. This will allow BeanSpecific customizers to
be
used in leu of the DynamicCustomizer.
Also finally figured out the IllegalAccessException problem with calling the
NodeList methods in the ACSTreeNodeElement classes, which turned out only to
happen when jikes was used for compiling. Implemented a work around.
