aja: fragment not updating

Hi,

I am stuck with ajax and fragment rendering.

I am new to both, spring and webflow, and try to do some ajax stuff. Ic ould not get the fragment to rerender so I stripped my code to a minimum.

have a bean with a "testNumber", an increaseTestNumber Method and a ui:fragment on my xhtml which only shows this number.

flow:

Code:

---

                <transition on="changeAddress">                       
                        <evaluate expression="card.owner.address.incNumber()" />
                        <render fragments="testFragmentXYZ" />                       
                </transition>

---

xhtml fragment:

Code:

---

                                            <ui:fragment id="testFragmentXYZ">
                                                            #{card.owner.address.currentNumber}
                                            </ui:fragment>

---

xhtml-action button

Code:

---

<sf:commandLink action="addressLookup" processIds="*" >

---

when i click the button, the "testNumber" gets increased correctly, means that the ajax call is succesful. the fragment does not seem to be rendered/updated. when i hit f5 and reload the entire page, the updated number is shown.

what am I doing wrong?

I'm not sure but you might need to use form or panel instead of fragment. It works in my case.

Code:

---

<h:form id="testFragmentXYZ">
#{card.owner.address.currentNumber}
</h:form>

---

thx, that already helped me, its working.
too much confusion with fragments i guess.


so far I have only been able to get it to work with forms (passing the form id into the render.fragfments attribute, e.g. <render fragments="myFormId" />

the problem is, that I want to partially render the form.

I could not find any info about which components I can use in the fragments attribute of render. if i use a div, it doesnt work, a outputlabel doesnt work.

To my knowledge, only JSF elements will work. HTML is out, and I've never had any success with ui:fragment, which is a faclets tag with no relation or connection to the render fragments action in SWF.

in the booking example, they use a "fragment". if the fragment is within a form they address it formid:fragmentid. will try it tomorrow at work.

Try adding a <div> as the first child of the ui:fragment. I believe its the contents of the fragment that are reloaded and not the fragment itself, therefore fragment needs a root node.
