Hello All
I am very new to JSF (v2.0) and I am attempting to learn it at places like netbeans.org and coreservlets.com. I am working on a very simple "add/subtract/multiply/divide" Java webapp and I have run into a problem. When I first started out, the application was enter two numbers and hit a '+' key and they would be automatically added together. Now that I have added more complexity I am having trouble getting the operation to the managed bean. This is what I had when it was just "add":
For the "answer" page, I displayed the answer like this:
I had the proper getters and setters in the Calculator.java managed bean and the operation worked perfectly.
Now I have added the other three operations and I am having trouble visualizing how to get the operation parameter to the bean so that I can switch around it. I tried this:
However, Glassfish complained that I have already used "operation" once and I am trying to use it four times here.
Any adivce/tips on how to get multiple operations to the managed bean so that it can preform the desired operation?
Thank you for taking the time to read.
