apex:pageMessages

This component displays all messages that were generated for all components on the current page, presented using the Salesforce styling.

Use this component to get user input for a controller method that does not correspond to a field on an sObject. Only <apex:inputField> and <apex:outputField> can be used with sObject fields.

Example

<apex:page standardController="Opportunity" recordSetVar="opportunities"
    tabStyle="Opportunity" sidebar="false">
    <p>Enter an alphabetic character for the "Close Date," 
       then click Save to see what happens.</p>
    <apex:form >
        <apex:pageBlock >
        <apex:pageMessages />
        <apex:pageBlockButtons >
            <apex:commandButton value="Save" action="{!save}"/>
        </apex:pageBlockButtons>
            <apex:pageBlockTable value="{!opportunities}" var="opp">
                <apex:column value="{!opp.name}"/>
                <apex:column headerValue="Close Date">
                    <apex:inputField value="{!opp.closeDate}"/>
                </apex:column>
            </apex:pageBlockTable>
        </apex:pageBlock>
    </apex:form>
</apex:page>
