HI,

My problem situation is that I want to populate a customer 'site' based on the customer name selected by user on Visual Force Page. Here is the code :

<apex:page sidebar="false" showHeader="false" controller="LeadsController" >
<apex:form >
 <apex:pageBlock title="Leads Info">
<apex:pageMessages id="pgMsg" />
       <apex:pageblockSection title="Customer">   
              
        <apex:inputField required="true" value="{!lead.Customer__c}" id="customer" >
        <apex:actionSupport event="onchange" action="{!GetValue}" reRender="site"/>
        </apex:inputField>
                                           

                                 <apex:outputLabel title="Site:" value="Site"></apex:outputLabel>    
                         <apex:outputText value="{!SiteName}" id="site"> </apex:outputText>

                
                             </apex:pageblockSection>

<apex:pageBlockButtons >
        <apex:commandButton value="Add" action="{!Add}" />
        <apex:commandButton value="Notify" action="{!Notify}"/>

    </apex:pageBlockButtons>


</apex:pageBlock>
</apex:form>
</apex:page>

 

The problem is that in the GetValue function in the controller, I try to use a select query where I pass 'lead.Customer__c' as a parameter to the where clause. However, lead.Customer__c will have the customer name only when i commit the lead obj to database. can you please tell me how can I access values of uncommitted visual force components (like inputfield) in Apex controller class?

 

thanks!
