form commandButton member variables
I have some get/set methods for which I don't have member variables(Well I have some static strings and I use them to put/get in properties file)
So in my jsp. I have couple of text fields and a button. If I put all the UI components in one form tag, then at runtime it complains that there is no property defined for attr (as in TestBean.attr the actual method will be setAttr, getAttr)
but If put twi form tags one for all the input components and one for the command buttons, it doesn't complain and works as expected.
So I would like to know why the first case failed and second case works fine
This one does n't work
