Checkbox causes a refrash

Hi

 

I have a table with the first column being a checkbox.

When checked this checkbox causes a refrash of the page and I want to avoid it.

I'm using the onclick event (with no call to the controller) but when I remove it the check is not saved to the controller and my logic is not working properly.

 

Need help, This is my code:

 

 

<apex:page Controller="SearchCheckedOutBooksController" showHeader="false" Tabstyle="Library_Order__c">
  <apex:sectionHeader subtitle="ECI Information Center Portal"/>
   <style>
      .activeTab {background-color: #2369FF; color:white; background-image:none}
      .inactiveTab { background-color: lightgrey; color:black; background-image:none}
   </style>
   <apex:tabPanel switchType="client" selectedTab=" tabCard" id="InfoCenterTabPanel" tabClass="activeTab" inactiveTabClass="inactiveTab">   
      <apex:tab label="News" name="News" id="tabnews">
         <apex:detail relatedList="false" title="true"/>
      </apex:tab>
      <apex:tab label="My Library Card" name="Card" id="tabCard">
         
            <apex:pageBlock title="Search My Library Orders" mode="edit">         
                <apex:form >                       
                    <label>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Subscriber ID to query&nbsp;</label>
                    <apex:inputText value="{!subscriberId}"/>
        
                    <apex:commandButton action="{!searchOrders}" value="Search" rerender="orderResults"/>                  
                </apex:form>                     
            </apex:pageBlock>
                    
           <!-- The results for each call are handled here. -->              
               
            <apex:outputPanel layout="block" id="orderResults">
                <apex:outputPanel rendered="{!IF(hasError == false,true,false)}">

                            </apex:form>

I suspect things are getting confused as you have several apex:form tags on your page - the advice in the docs is only to have one.

 

Try putting the whole page into a single form - that should propagate your changes.

This is documented behaviour - the Visualforce Developer's Guide has this to say about the actionsupport action attribute:

 

--- snip ---

 

If an action is not specified, the page simply refreshes.

 

--- snip ---

 

Can you explain a bit more about what you are trying to do?  e.g. do you need to update values in the controller in order to redraw part of the page?

I got the same behaviour when I specified an action (I removed it in the code I posted).

In the controller I'm "collecting" all the checked rows executing some APEX code, here the method that does that when an action button is clicked:

 

 

    public void searchOrders(){
		
		myPendingOrders.clear();
		myCheckedoutOrders.clear();
		myOlderOrders.clear();
		
        try{
	        Library_Sunscriber__c sub = [SELECT ID, Name, Subscriber_ID__c, Email_address__c,
	                                         (SELECT ID, Name, Type__c, Status__c, Title__r.Name, Information_Retrieval__r.Name, 
	                                                         Order_Date__c, Fulfillment_Date__c, Return_By__c
	                                          FROM Library_Orders__r)
	                                     FROM Library_Sunscriber__c
	                                     WHERE Subscriber_ID__c =: subscriberId]; 
	        
	        for(Library_Order__c order :sub.Library_Orders__r){
	            
	            if(order.Status__c == 'Pending'){
	            	myPendingOrders.add(new tableEntry(order));	
	            }   
	            else{
	            	if(order.Status__c == 'Fulfilled' && 
		               order.Type__c != 'Information Retrieval'){                     
		               		myCheckedoutOrders.add(new tableEntry(order)); 
		            }
		            else{   
		            	myOlderOrders.add(new tableEntry(order));     
		            }
	            }
	        }
	        
	        hasError = false;               
        }
        catch(Exception e){
        	hasError = true;        
        } 
    }

 

 

If I remove the actionSupport all together the code does not work at all (for some reason the isSelected is not being updated on the controller)

 

Thanks

Many thanks

 

Now it works as expected.

 

I have another issue going though.

 

I have three tabs on this tab Panel. When I click on the Search button my tables are being populated but when I click on the Delete Order button along with the action being performed the page is refrashed and the 1st tab is being desplayed (I'm on the 2nd when I do it). Why does it jump to the 1st tab?

Why is the different behavior?

Your search button has a rerender attribute associated with it - the other actions don't so they cause the entire page to be refreshed.

Got it,

 

Thanks a lot
