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

[Tom Ware <tom.ware@xxxxxxxxxx>]

Hi Chris,

  I ran the static weaver on some test classes.  It looks like there is a (very 
minor) bug with the static weaver.  It ignores the "eclipselink.weaving" flag. 
This is minor for two reasons:

1. If you are running the static weaver, it is fairly safe to assume you want 
some weaving
2. It does not ignore the other weaving flags.  (e.g. setting property 
name="eclipselink.weaving.lazy" value="false" causes weaving of lazy xToOne 
mappings to remain unweaved)

  To debug, I suggest the following:

1. Set the eclipselink.weaving flag in your persistence unit to "static"
2. Run several times and try to set each of the following flags to "false" 
individually.  See if any one flag allows you to succeed.  That will help 
isolate which part of the weaving is getting in the way.  With that information, 
we can decide what is going wrong, and decide if there is anything that can be 
done in EclipseLink to solve this issue.  Here are the properties (remember, 
they default to true):


eclipselink.weaving.lazy
eclipselink.weaving.internal
eclipselink.weaving.changetracking
eclipselink.weaving.fetchgroups
