Calling interval of actionpoller from Controller

Hi,

 

I am calling a method from my controller every 5 seconds.

But I want to dynamically change the interval by adding a custom setting and calling the custom setting in apex class and

referring that in the interval attribute of actionpoller.

 

But when I tried that, the method is not getting called every 5 seconds. It is taking the default interval as 60 seconds.

 

I also tried by creating an Integer variable in the controller and called that in the interval attribute of actionpoller.

 

Following is my code which I am trying:

public class exampleCon {
    Integer count = 0;
     Integer interval=5;                   
    public PageReference incrementCounter() {
        count++;
        return null;
    }
    public Integer getinterval(){
        return interval;
    }                 
    public Integer getCount() {
        return count;
    }
}

 

<apex:page controller="exampleCon">
    <apex:form >
        <apex:outputText value="Watch this counter: {!count}" id="counter"/>
        <apex:actionPoller action="{!incrementCounter}" rerender="counter" interval="{!interval}"/>
    </apex:form>
</apex:page>

 

 

Please let me know any suggestions.

 

Thanks

Arvind

I did come up with a workaround that seems to work. 

In a nutshell create 2 actionPollers with different "rendered" variables. In the controller, instead of passing the variable to the "Interval" parameter, set your boolean for "render" parameter.

Like Such...

VF Page:
        <apex:actionPoller action="{!reload}" rerender="mainform" interval="5" rendered="{!render120}"/>
        <apex:actionPoller action="{!reload}" rerender="mainform" interval="10" rendered="{!render600}"/>


Class:
//declare variables
    public boolean render120 {get;set;}
    public boolean render600 {get;set;}

then in the constructor:

        //set refreshTime boolean variables        
        if('x'=='x'){ // set needed conditions here
            render120 = true;
            render600 = false;
        }
        else{
            render120 = false;
            render600 = true;
        }

* make sure you dont have multiple "true" variables

I know this is not pretty, but it worked for my basic requirement.
