    rich:hotKey (since I saw the blog post)

    John Ament Master

      i'm trying to use rich:hotKey like in the example. i've tried a few iterations of it, and none work. Any ideas?

       <a4j:form ajaxSubmit="true">
       <h:inputText value="#{viewLiveBlogBean.postText}" id="postText">
       <a4j:support event="onkeyup" reRender="availableCharacters" />
       <a4j:support event="onblur" reRender="availableCharacters" />
       </h:inputText>
       <a4j:commandButton id="addComment" action="#{viewLiveBlogBean.addPost}" value="Add Comment" reRender="postText,availableCharacters"/><br />
       <h:outputText value="#{viewLiveBlogBean.availableCharacters}" id="availableCharacters" /> characters left
       <rich:hotKey key="return" handler="#{rich:element('button')}.click()"/>
       </a4j:form>

          now that i'm looking at it, firefox's webdeveloper plugin is pointing this out

          Error: syntax error
          Source File: http://localhost:8080/view/liveBlog/FirstLiveBlog
          Line: 35, Column: 90
          Source Code:
          new Richfaces.hotKey('j_id31:j_id36','return','', {timing:'immediate'}, function(event) { .click() });

            Hello,

            I'm looking at how:

            #{rich:element('button')}.click()
            is output:
            function(event) { .click() }


            Please check that id='button' component is present on the page

              No, it's not, and it's not on the blog post either (thus implying that it's not needed).

              I did however add it at one point and assumed it was the wrong move because I get a stack trace like this:

                nt: viewLiveBlogBean

                is @Synchronized really necessary here?

                P.S. Can you please post a link to the blog post you are talking about?

                  I don't have it marked @Synchronized...

                  The form works fine if i actually click the button, so i don't think it's that.

                    Try this:

                    <rich:hotKey key="return" handler="#{rich:element('addComment')}.click()"/>

                      Are you assuming the button has id addComment? If so, it's no different than if it had the id button.

                        Works for me:

                        <a4j:form ajaxSubmit="true">
                         <h:inputText value="" id="postText">
                         <a4j:support event="onkeyup" reRender="availableCharacters" />
                         <a4j:support event="onblur" reRender="availableCharacters" />
                         </h:inputText>
                         <a4j:commandButton id="addComment" value="Add Comment"
                         reRender="postText,availableCharacters" />
                         <br />
                         <h:outputText value="" id="availableCharacters" /> characters left
                         <rich:hotKey key="return"
                         handler="#{rich:element('addComment')}.click()" />
                         </a4j:form>


                        Yes, as by your code id of the button is 'addComment'. So, after you changed from 'button' to 'addComment', do you still see Javascript error or server exception? Also looks like there are concurrent AJAX requests, can you please remove <a4j:support event="onkeyup" reRender="availableCharacters" /> and check?

                          well hmm this seems like odd results to me. This block works perfect..

                           <a4j:form ajaxSubmit="true">
                           <h:inputText value="#{viewLiveBlogBean.postText}" id="postText" class="postText">
                           <a4j:support event="onkeyup" reRender="availableCharacters" />
                           </h:inputText>
                           <a4j:commandButton id="button" action="#{viewLiveBlogBean.addPost}" value="Add Comment" reRender="postText,availableCharacters"/><br />
                           <h:outputText value="#{viewLiveBlogBean.availableCharacters}" id="availableCharacters" /> characters left
                           <rich:hotKey key="return" handler="#{rich:element('button')}.click()"/>
                           </a4j:form>
                          


                          So the question is, did having 2 events occurring break it? Or just the fact that it's a blur event.

                            just blur event fired when you click the button. So in your case - two concurrent request sent. and seems its causes the problem.

                              while i can see that happening, i don't get why hitting enter would blur the field, the cursor's not leaving it... my thought was that using a hotkey emulates the action, rather than actually doing it. or does richfaces event model state that click moves the active element to the button?

                                True, click() should not move focus. I've added onblur handler and do not see it is triggering when typing in input in IE7 & FF3. However I see it blurring in Chrome. Are you using Safari or Chrome?

                                  Correction: when typing in input and pressing return
