Re: [eclipselink-users] Odd problem with BeansBinding since upgrading Ec

[Tom Ware <tom.ware@xxxxxxxxxx>]

Hi Chris,

  I am not familiar with how Beans Binding works, but I suspect it ties your 
GUI elements to either the fields or the get/set methods in your Object.  These 
are also the things we weave.

  One thing you could do to debug is to decompile your weaved classes and put 
breakpoints in the methods that access your instance variables.  (likely your 
getter and setter methods).  Hopefully that can help you ascertain what is 
happening.

  Another debugging option is to try to determine what part of the weaving code 
interferes with the way things are working.  You can do that by using 
persistence unit properties to disable/enable various parts of our weaving using 
the following properties:

eclipselink.weaving.lazy=true/false - adds an EclipseLink ValueHolder object for 
lazy xToOne mappings and methods to control it

eclipselink.weaving.eager=true/false - adds an EclipseLink ValueHolder object 
for eager xToOne mappings and methods to control it to allow other persistence 
units to treat the same object as lazy

eclipselink.weaving.internal=true/false - adds some internal optimication

eclipselink.weaving.changetracking=true/false - more internal optimization

eclipselink.weaving.fetchgroups=true/false - enables fetch groups

  The default is true for all but eclipselink.weaving.eager.

-Tom
