SalesRed Variable value being lost despite controller "set" being called correctly.
Hello,
I am trying to set a string vaue in my controller class but I'm finding th following unusual scenario resulting:
- Note I've tried to set my value using an actionFunction and subsequently I'm not trying via a hidden field.
- I click on the following button
<apex:commandLink styleClass="btn" value="Save Image Order" action="{!changeImageOrder}"/>
<apex:inputHidden value="{!currentImageOrder}" id="theHiddenInput"/>
In my controller, for String currentImageOrder the setter is called and prints out the value ok in my debug as follows.
public String currentImageOrder{get;set{
system.debug('in image order set ' + value);
}
}
In funciton "changeImageOrder" String currentImageOrder is null.
public PageReference changeImageOrder(){
system.debug('in chngorder111 ' + currentImageOrder);
system.debug('in chngorder222 ' + this.currentImageOrder);
return null;
}
As the setter is called first should the value not be set when I debug in changeImageOrder?
Thanks in advance for any help.
Hi,
Controller
public String currentImageOrder{get;set;} //Declare globally
public PageReference changeImageOrder(){
system.debug('in chngorder111 ' + currentImageOrder);
system.debug('in chngorder222 ' + this.currentImageOrder);
return null;
}
Page
<apex:commandLink styleClass="btn" value="Save Image Order" action="{!changeImageOrder}"/>
<apex:inputHidden value="{!currentImageOrder}" id="theHiddenInput"/>
Declare the get;set; like that and see what happens.

What is the initially value for "currentImageOrder" ?
Are you setting anything to "<apex:input:Hidden/>" ?
If you havent initialised the value of "currentImageOrder" it will be always be null. To pass a value to the controller probably you have to set a value to your inputHidden using js may be ?
