[platform-dev] netbeans binding

[hayford.osei]

I have a crub application in progress.
I would like to bind my data from DB to some dropdown list or Combox.

I tried to use add other and added an EntityManager (Eclipselink). At
this point the app runs fine.
I added the Query select c from customer c... The application fail
with null pointer

I suspect the issue is with either definition of EntityManager or
Query... they way input this in the graphical interface.
Can anybody point out where am going wrong...

I really need that functionality...
ps If i write the code without the gui the query runs fine.

Have you right order of the creating the object?

First you have to create Entitymanager object, after that query. I was using this crud tutorial and it works for me.

Hello, what works for you?
Are you able to bind your result to a ComboBox or JList..

I too have followed the tutorial and it works i want to extend that.. so as to populate a combobox, jList with the result.

Any ideas will be welcome.
