onclick event
Apex repeat function here would repeat the days of the week, iterating from Monday to Sunday also displaying the day alongside.
My problem is in the prevWeek.
prevWeek is a button. (supposed to be)
When it is clicked I want the changes in goprev to take place.
I need wcTopBar to display the previous weeks days.
Pl take a look at
<apex:actionSupport event="onclick" action="{!goprev}" rerender="wcTopBar" />
and let me know what is deficient to do the job.
<apex:outputPanel id="wcTopBar" layout="block" styleClass="containerAD noscroll" style="height: 37px;">
<div class="overflowContainer">
<div class="weekLabels">
<apex:repeat value="{!daysOfWeek}" var="d">
<div class="{!d.divClass}">
<div><span style="{!d.spanStyle}"><apex:outputText value="{!d.dayName}" escape="false" /></span></div>
</div>
</apex:repeat>

Hello,
Have you checked that serverside function is calling or not ?

yes I did
The app was working fine...
until I got this error
Attempt to de-reference a null object
An unexpected error has occurred. Your development organization has been notified.
Check Controller / ControllerExtension class and see if there is any null Object and any value is getting assigned to this object. This error generally comes when we assign value to some variable/ Object which is initialised with null.
