Button not submitting/ firing action code.

Question

Hi All.
In Creator, I seem to be having problems with a specific page. It doesn't seem to matter how many buttons I try to drop on a page (with a number of databound controls on it), but the buttons just don't seem to fire off the backend code. according to the action property of the button, the backend code associated with that method should fire, but it just doesn't. I've tried just throwing a button on the page and putting something as simple as
log("the code in the button got fired");
return null;But even something so simple as that does not fire.
In any other page, that code works fine (obviously). I just hate the idea of having to re-develop the page from scratch when I encounter such an issue (especially after how much time it took given all the data bound controls). If anyone can point me to someone having a similar issue, or could give some feedback on this one It would help a great deal (even though this is quite ambiguous.)

Answer 1

you were 100% correct. I recieve the following message:
Validation Error: {0}Value is not valid
I recieve this on RadioLists that I have bound to a numerical column on an Oracle database. The String based bindings seem to work fine. Perhaps you can inform me of any mistakes I have made with the following when I expect the selection to bind to the numerical column:
Integer zero = new Integer(0);
Integer one = new Integer(1);
listYesNo = new java.util.ArrayList();
listYesNo.add(new SelectItem(one,"Yes",""));
listYesNo.add(new SelectItem(zero,"No",""));
// same error when using code as commented below too:
//        listYesNo = new java.util.ArrayList();
//        getListYesNo().add(new SelectItem("1","Yes",""));
//        getListYesNo().add(new SelectItem("0","No",""));
