Hitting enter does not activate the Search Button

Question

I have a page where the Search Button is clicked to perform a search. The search button works ok when it is clicked. But nothing happens when the Enter key is pressed. I also want the searchAction to be called if the user hits the enter key.
The code for the button is :
<tr:panelButtonBar>
                        <tr:commandButton text="Search"
                                          onclick="validateRequiredFields(this)"
                                          action="#{amyBean.searchAction}"></tr:commandButton>
                  </tr:panelButtonBar>Thanks in advance .....

Answer 1

The enter key will only invoke a button if the parent form has the focus and the desired button is the firstnext button after the focus.
