VE Instrospection problems [message #136398]

Originally posted by: bcorbett.titledata.com

I am trying to do some maintenance on some frames with developed with IBM
VAJ originally. In the past versions of VE and Eclipse, I did not have
problems opening up the frames with VE, but now I am getting Introspection
Errors. VE is
complaining about com.ibm.as400.access.Record, which is apart of JTOpen.

When I first encountered this problem, I recreated my frame using VE with
no problems. However, as I look at more frames with VE, I am getting
Introspection Errors more often.

Currently, I am using VE 1.20.v20060918_M in Eclipse 3.2.1

It may be of note that I am using jt400 4.9.0.

Any help would be appreciated.

The introspection error is due to the beaninfo you supplied not
following the Beaninfo specifications. RecordBeanInfo class is
describing a VetoableChangeListener but the method defined as
vetoableChange does not have a PropertyChangeEvent as an argument. That
is required.

Take a look at RecordBeanInfo at line 78. That is were it is failing. It
is trying to create an EventSet and the event set name is
"vetoableChange". Such an eventset requires a listener that has a method
"vetoableChange(PropertyChangeEvent evt)".
