Target Unreachable, identifier 'donorHome' resolved to null
I used the JBoss Tools wizard to reverse engineer a gui from a table (File - New - Seam Generate Entities) which I am pretty sure is just using the generate-entities seam script.
This worked great when I made a table called person
with a lastname and firstname column.
It made the gui and all that...
I then tried to manually make my own called donor
. I copied all of the person code that I could find and changed it to donor
.
It works... but when I go to the person page it says
Target Unreachable, identifier 'donorHome' resolved to null
I figure that it is using the @Name annotation to get a reference to the 'donorHome' object. Do I need to do anything else for the JSF to be able to reference the 'donorHome' class?
So, here is my code:
DonorEdit.xhtml:
