You'll need the stack trace and see where that is being thrown.

There you go.
You're doing something wrong on line 601 of main.java.
Inside the initComponents() method.

It seems to involve addBinding() of the BindGroup class, and adding a binding for "" which already exists.

So stop it.

[seristee]

600 binding = org.jdesktop.beansbinding.Bindings.createAutoBindi ng(org.jdesktop.beansbinding.AutoBinding.UpdateStr ategy.READ_WRITE, reportsTable, org.jdesktop.beansbinding .ELProperty.create("${selectedElement.review}"), sreviewfield, org.jdesktop.beansbinding.BeanProperty.create("dat e"), "");
601 bindingGroup.addBinding(binding);
602 binding = org.jdesktop.beansbinding.Bindings.createAutoBindi ng(org.jdesktop.beansbinding.AutoBinding.UpdateStr ategy.READ_WRITE, reportsTable, org.jdesktop.beansbinding .ELProperty.create("${selectedElement != null}"), sreviewfield, org.jdesktop.beansbinding.BeanProperty.create("ena bled"));
603 bindingGroup.addBinding(binding);

i have removed the binding and i still get the same error

[Tolls]

You're binding multiple properties with the same blank name.
There's no way anyone here can debug that.
You'll need to either step through the code with a debugger or stick lots of logging in there to see what's going on.

And when you post code please use [code] tags [/code].
That's unreadable...

thanks for the info I managed to find the problem. in netbeans bindings I never put in an identifier for the bindings. I have now rectified the problem and program working again.. thanks for the help

[Tolls]

Which is what the exception was telling you.
Good you got it sorted.
