Nested span issue
By: Dennis (dennis-) - 2008-03-24 20:41
Hi,

it seems like everytime a component is re-rendered after an AJAX call,
it gets wrapped in a new <span />-Tag. If the rendered component
itself uses the ajax tag the J4Fry JavaScript code gets inserted into
each of these nested spans!

Example:
<f:view>
<h:form id="myForm">
<h:inputText id="in" value="#{bean.myValue}">
<fry:ajax event="onclick" action="#{bean.update}" reRender="result" /
>
</h:inputText><br />

<h:outputText id="result" value="#{bean.myValue}" />
</h:form>
</f:view>

Everytime I click on the h:inputText field the rendered outputText is
wrapped in one <span>-Element more.
I use Firebug (Inspect) and WebDeveloper toolbar (View Generated
Source) for analyzing such stuff.

Thanks in advance for any hints.

Regards,
Dennis

Dear Dennis,

Thank you for digging into the generated HTML structure. I will
set up your example to debug the behaviour you describe. Which JSF
implementaiton and which web container are you using?

Regards,
Ganesh

Hi,

I see the same behaviour. Actually there are 2 separate
concerns:

- The routine that is responsible for rendering the j4fry
script tag only once per page is incorrectly initialized when an AJAX
enabled tag is rerendered.
- When replacing a component the replacement is always
wrapped in a span tag. This is currently done on pupose in
j4fry_common.fry, line 186. We'll need to think about this because
frequent AJAX updates (e.g. onkeyup) may generate loads of spans.

I will create bugs in the tracker for both.

Greetz,
Ganesh
