valueChangeListener of a selectBooleanCheckbox
I run into a problem where my checkbox seems to lose its ValueChangeListener
on a mobile browser like Pocket IE, IE Mobile.
Here is what I have on my JSF page:
<tr:form>
<tr:panelGroupLayout>
<tr:selectBooleanCheckbox text="selectBooleanCheckbox 1"
label="Label 1"
valueChangeListener="#{bean.valueChange}"
id="check1"
autoSubmit="true"
/>
</tr:form>
I have a backing bean 'Bean' in 'session' scope that looks like this:
public class Bean {
public Bean() { }
public void valueChange(ValueChangeEvent valueChangeEvent) {
// Add event code here...
System.out.println("valueChange event is being called !");
}
}
When the page first comes up, I click on the checkbox. I DON'T see the
message "valueChange event is being called". But when
I click again, the same ValueChangeListener gets invoked and displays the
message "valueChange event is being called".
Does anybody know what I did wrong?
BTW, this works fine on Desktop applications. I am wondering why it does not
for mobile browsers. Does valueChangeListener for a checkBox has a
dependence on the type of Browser ?

That does look wrong, but is that the cause of this bug?

I dug up the mountain and found this mouse:
There was a typo while building request string:
do you see it ?
else if (element.type == "checkbox" && element.checked == true)
datatosend += ( element.name + "=" + escape(element.value) + "&
");
No...? Look at the space after '&' and before the closing brackets :-)

When I remove the code that would submit the value each time it is checked
(check1=t) from the Core.js , the valueChangeListener gets called properly.
But, this is obviously not the right thing to do since the user might need
to submit a value.

Re: Re: Re: valueChangeListener of a selectBooleanCheckbox

Upon checking a check Box, getSubmittedValue() does not get called. Upon
unchecking it does get called.
HTTP request differs in t.o the attribute check1 (check1 being the
user-assigned ID of the checkBox). It does not get passed upon unchecking.
It gets passed with a value 't' upon checking.
Upon checking:
check1=t
&org.apache.myfaces.trinidad.faces.FORM=_id1
&org.apache.myfaces.trinidad.faces.STATE=%2138234b14
&source=check1
&event=check1
&partialTargets=
&partial=true
Upon Unchecking:
org.apache.myfaces.trinidad.faces.FORM=_id1
&org.apache.myfaces.trinidad.faces.STATE=%2138234b14
&source=check1
&event=check1
&partialTargets=
&partial=true
I am investigating this further but if you have any suggestions, let me
know. Kindly note that Desktop browsers have the same HTTP requests and it
works there.

Puzzling. I'd suggest you have a look at what HTTP parameters
are getting sent, and what the Renderer's getSubmittedValue()
method returns.

Hi Adam,
Please note that valueChangeListener is called when it is UNCHECKED
and not called when it is CHECKED (reverse of what you wrote). This
happens consistently provided my bean is in SESSION scope.

Is it consistently that you don't get it when it's
unchecked, but do get it when it's checked?
