Patrick Mayer 4 Saving VF checkbox value back to controller
Why does this only save the value of a boolean back if I call an empty function? I have tried it with the alternative second line that I have commented out and this does not update the controller as I would like. Is there a better way to do this? My solution seems hacky.
public class DemoController {
public boolean activated { get; set; }
public DemoController() {
activated = false;
}
public void doNothing() {}
}
<apex:page controller="DemoController">
<apex:form id="form">
<apex:inputCheckbox value="{!activated}" >
<apex:actionSupport event="onclick" action="{!doNothing}"/>
<!--<apex:actionSupport event="onclick" rerender="test"/>-->
</apex:inputCheckbox>
</apex:form>
<apex:outputText id="test" value="test" rendered="{!activated}"/>
</apex:page>
Your "hacky" way is the correct way to this in Visualforce. You will however want it to be onChange instead of onClick. How are you testing that it updated in the controller? Are you look at this by seeing that the outputText is updated?
