Subject [jira] [Commented] (MYFACES-3696) Button rendering itself after ajax request loses type and other attributes
Date Thu, 04 Apr 2013 13:13:25 GMT


dennis hoersch commented on MYFACES-3696:

Which classes are involved in the solution?

If I use (only) the updated org.apache.myfaces.shared.renderkit.html.util.ResourceUtils I
have still the described behavior. The FormSubmitScript is still included in the ajax response.

The call that renders the submit script (HtmlRendererUtils.renderFormSubmitScript() (delegating
to 'HtmlJavaScriptUtils')) is some lines below the 'ResourceUtils.renderDefaultJsfJsInlineIfNecessary()
in 'HtmlButtonRendererBase.encodeEnd()'.

Maybe I don't understand the last sentence in your response correctly. Why should the submit
script be included in ajax responses?

(Regardless: If I understand the JavaDoc (and implementation) of PartialViewContext.isPartialRequest()
right it includes already the check for an ajax request?)

>          Issue Type: Bug
>    Affects Versions: 2.1.10
>            Reporter: dennis hoersch

>             Fix For: 2.0.17, 2.1.11
> The renderer for command buttons and command links inserts a special form submit script
inline before the first button (or link) on a page is rendered by calling 'org.apache.myfaces.shared.renderkit.html.HtmlJavaScriptUtils.renderFormSubmitScript(FacesContext)'
> I have a CommandButton with ajax behavior that renders also itself like this:
>     <h:form id="testForm">
>         <h:commandButton
>             value="do somethings">
>             <f:ajax execute="@this" render="@this" />
>         </h:commandButton>
>     </h:form>
> After the ajax request is done and the markup is replaced by the Javascript function
_Dom.outerHtml() the html in the browser ends up with this:
>     <input
>         type="text/javascript"
>         onclick="...submit code ..."
>         value="" />
> and is not a 'button' anymore (Firefox renders it as text input field).
> The cause is that the update response for the button contains as first element the inline
script code.
> Is it necessary to render the inline script on ajax requests?
> Changing HtmlJavaScriptUtils to insert it only on non-ajax request the example above
works as expected at the first glance.
>     public static void renderFormSubmitScript(FacesContext facesContext) throws IOException

>         if (facesContext.getPartialViewContext().isAjaxRequest())
>         {
>             return;

>         ...
