Ron (or others),

Thanks again - I've lost count of the number of times of used your posts to solve a problem.

I used the post above to add a commandbutton to each row of a pageBlockTable.  When clicked, it updates a field on the record displayed in that row.  I also asked it to rerender the table, because the updated field value excludes it from the the query results for that table.  Basically, click the "OK" button and drop that item off the table.

But, rerendering the pageBlockTable doesn't refresh the list.  I also have a selectList where the user chooses which Opportunity Owner to view.  It also rerenders the table, and that works fine.  Changing away from the current Opportunity Owner and then back in that selectList shows the item has been removed from the pageBlockTable.  They use the same rerender instructions, so I assume the problem involves asking for the rerender from inside the table itself?

I've tried moving the id up to the pageBlock and to an outputPanel surrounding it, but the same behavior takes place.  It won't update the list from the commandbutton click. 

I've tried to figure out how to call the query that populates the table from the button's action, but that didn't work.  I've tried creating a second query for table contents and trying to force the table to use that instead.  I'm afraid I just know enough to be dangerous.

Any ideas?

Here's my page:

<apex:page controller="displayAtRiskopps" tabStyle="Opportunity">
    
    <apex:form id="AtRiskOppForm">
        <apex:outputPanel rendered="true"> 
        <apex:pageBlock >
        
             <apex:panelGrid columns="2">
                <apex:selectList id="OppOwner" value="{!oppowner}"  multiselect="false" size="1">
                   <apex:selectOptions value="{!items}"/>
                   <apex:actionSupport event="onchange" rerender="OppTable"/>
                </apex:selectList>
             </apex:panelGrid>
  
        <apex:pageBlockTable id="OppTable" value="{!Opps}" var="o" rendered="true"> 
            <apex:column > 
                 <apex:commandButton value="OK"/>
                     <apex:actionsupport event="onclick" action="{!markReviewed}" rerender="OppTable">
                         <apex:param name="oppid" value="{!o.id}" />
                     </apex:actionSupport>
            </apex:column>
            <apex:column > 
                 <B><apex:outputLink value="/{!o.id}" target="_blank">View</apex:outputLink></B>
            </apex:column>
            <apex:column headervalue="Opportunity Name" value="{!o.name}"/>
            <apex:column headervalue="Stage" value="{!o.Stagename}"/>
            <apex:column headervalue="Amount" value="{!o.Amount__c}"/>
        </apex:pageBlockTable>
    </apex:pageBlock> 
    </apex:outputPanel> 
   </apex:form> 
</apex:page>

 And here's the relevant parts of the custom controller:

    public List<Opportunity> getOpps() {
        OppList = [SELECT id, name, ownerid, account.name, amount__c, StageName, Date_Entered_Current_Stage__c, At_Risk_Review_Date__c, amount, Subscription_Amount__c  
                FROM Opportunity 
                WHERE ownerid = :oppowner AND ((At_Risk_Review_Date__c = null) OR (At_Risk_Review_Date__c < :date.today().addDays(-90))) limit 20];
        return OppList;
        
    }


    public PageReference markReviewed() {
        
        ID oppid = ApexPages.currentPage().getParameters().get('oppid');
        Opportunity reviewOpp = [Select id, At_Risk_Review_Date__c from Opportunity where id = :oppid];
        reviewOpp.At_Risk_Review_Date__c = date.today();
        update reviewOpp;
        return null;
    }
