BBeaird Ajax rerender after controller record update
I feel like maybe I don't understand the purpose of "rerender." I want to be able to click a button that calls a method in my controller. The method then calls out to a webservice to grab a value. The method then updates the record. Finally, the fields should be refreshed on the page. From looking at countless examples, here is the code I've come up with. The problem is that nothing is being rerendered after the controller method finishes. If I refresh the page manually, I see the updated fields. How can I make the fields refresh without having to manually force it?
Page
<apex:commandButton value="test" status="myStatus" action="{!testing}" reRender="theblock"/>
<apex:actionStatus startText="(processing...)" stopText="" id="myStatus" />
<apex:pageBlock id="theblock" >
<apex:outputField value="{!Asset.Current_Hours__c}"/>
Controller
public void testing(){
updateSingleRecord(obj.Id); //Method that does a webservice call and also updates Current_Hours field on the record.
}
I checked your case and It was working for me , only thing that I was not updateing using webservice method. But i will suggest you do like this
Way 1 : Return type of action in controller change it to pagereference and return like this
return ApexPages.currentPage();
Way 2 if you only want to rerender one section
<script>
function callAction()
{
jsTesting();
return false;
}
</script>
<apex:actionFunction action="{!testing}" reRender="theblock" name="jsTesting" />
<apex:commandButton value="test" status="myStatus" onlcik="return callAction();" />

I found my problem. It wasn't changing upon rerender because I was saving a copy of the Asset object rather than the actual Asset object that has everything bound to it and is gotten in my controller extension with objAsset= (Asset)controller.getRecord();
Once I switched things around to deal directly with that object, everything rerendered perfectly.
