Also note, that all woodstock components refresh correclty when I use

My only problem happens with the Calendar component. 
Thanks. 
  

Could you please try using the debug option so that you could gain more information on what exactly the error is?
Maybe there is something in the calendar.js file thats causing the problem?
Since the calendarField widget actually exists on the dom page and you are updating a sub-widget of calendarField,
 i dont understand why "this.domNode" for the calendarField widget should be returned as null. The calendar widget
is not changing any properties on the calendarField widget.

Hello Venkatesh, 

"
When are you trying to fire an ajax rransaction? what data are you 
returning back in your ajax response?"


Well here is my initial requirement: 
I have a field called ID where the user inserts the ID of the object he is
trying to retrieve. 
When the user leaves the textfield (onChange) I want to submit the value
of the ID asynchroneously to the server. AFTER the ID being submitted and
the object being fetched on the server side, I want to asynchroneously
update MULTIPLE components on the page at the SAME time. 

The thing is, the current implementations on submit and refresh do not
allow me to achieve this behavior. 
In fact, myNode.submit(field1, field2) will submit field1 and field2 while
submitting myNode; and myNode.refresh('field1 , field12') will submit
field1 and field2 while refreshing myNode.
There does not seem to be a way to refresh field1 and field2while
submitting myNode.

Moreover if I do: myNode.submit(); field1.refresh(); field2.refresh() :
this does not garantee that field1 and field2 will wait till myNode has
been submitted before attempting a refresh ... 
    

You could try doing field1.refresh(myNode) and field2.refresh(myNode)
Though you risk submitting the data of myNode twice to the server.

Another way of accomplishing the same thing would be to subscribe to the end event topic
of field1.refresh(myNode)  by field2 and do a field2.refresh() when field1's end event topic is broadcast.

But in the above use cases, i dont see you trying to update a calendar anywhere?

This is why I dropped using refresh and submit provided by woodstock
components and opted for fireAjaxTransaction wich allow me to specify
which components to submit and which ones to refresh in a single call. 


"Also, are you giving the id of the calendarfield widget or the calendar 
widget?"

No I am actually sending the id of the whole calendar. 

    

Thanks a lot!

Hi Rasha,

When are you trying to fire an ajax rransaction? what data are you 
returning back in your ajax response?
Also, are you giving the id of the calendarfield widget or the calendar 
widget?

The code you are referring to :

webui.@... = function(props)
{
    // Check whether the calendar associated with this particular 
calendarField
    // broadcasted the event.
    if (props.date != null && props.id == this.calendar.id) {
        // Set the selected date on the field.
        this.domNode.setProps({value: props.date});
    }
    return false;
}

this.domNode refers to the calendarField widget's dom element.

Try appending the "?debug" parameter to your url
This will help you get a more meaningful error.

You can also try using  firebug to get more information.

Below is a code snippet on how I am trying to update my components
asynchroneously using fireAjaxTransaction: 


DynaFaces.fireAjaxTransaction(this, { execute: 'IdOfComponentToSubmit',
render:'IdOfComponentToRender'}); 

When IdOfComponentToRender is that of a textfield, table, button etc...
there is no problem and everything works correctly . 
But When IfOfComponentToRender is that of a calendar, although the
refresh
takes place correctly, whenever I attempt to pick another day from the
calendar, I get a javascript error saying: this.domNode is null. 
I followed the javascript code for the calendar component, and this
could be
taking place in the calendarField.js file at: 
webui.suntheme.widget.calendarField.dayClicked=function(_1){ 
if(_1.date!=null&&_1.id==this.calendar.id){ 
this.domNode.setProps({value:_1.date}); 
} 

Is there something I'm doing wrong, or is this a bug in the Calendar
component? 
Thanks. 
Rasha
