Issue sending variables to a controller

I'm using javascript to set a value in an apex:inputHidden field. That value is not passed on to the controller even though it is bound to a variable in the controller. 

 

Javascript: 

 

        document.getElementById('timeEntry:j_id82:0:j_id86:j_id88:j_id89:selectedDay').value = currentDate;

 

Visualforce:

<apex:inputHidden id="selectedDay" value="{!selectedDay}" />

 

APEX:

  public String selectedDay { get; set; }

 

I used javascript alert() statements to check the value of the apex:inputHidden field and the value of currentDate is being set properly. However, when using selectedDay in my controller, it is null. The inputField has the value but the controller is not aware of the field's contents.

 

Am I missing a step in here somewhere that allows this to happen? 

 

Thanks.

i think you are missing an action, but i don't see enough code to determine.

 

here is a working example of using inputHidden to pass fields from a form into a controller.

Hello Ron,

 

Can i pass values into Hidden fields if my value is inside a Repeat??

 

In this case, i get the ID dynamically generated ... so i am not able to pick the exact ID.

 

Is there a solution to this problem??

 

Thanks,

Cool_D
