Page with PartialTriggers is not working when it loads for the first time

Question

Hi All,
I am experiencing unexpected behavior when using partial triggers and this recurres every time the page loads and the second time it works fine.
Here is the requirement, The page has a check box, when checked, two text boxes should be disabled. When unchecked the two fields should be enabled.
(The fields are Start Date Time and End Date Time in the code below). I am also handiling the Date Validations on value change listener of Start Date time and have no issues on that.
When I try to enter the dates on page load (The check box - "Process Full Indicator" is not selected), I enter the required fields (PEID, Dates and check the Process IAF and Process SMS check boxes and click on the ProcessRFI Button, the date fields are emptied and nothing happens. When i redo the same thing the second time, it works.
The button invokes a BEPL process.
One of the links suggested that I use the partialTrigger tag in the parent layout, I used in the panelFormLayout and it sill did not reflect.
I am facing the same issue in an other page that is reteriving data from a DB Table. As I notice, both the pages are invoking dataControlls. Not too sure if it is related.
Kindly help.

Hi John,
My page is not a part of a task flow. The whole app is an Admin app comprising of multiple individual pages navigated using Menu.
I have tried to run this page individually on my local machine as well as when deployed on the WLS server. The behavior is the same.
Kindly advice,
Thanks,
Ram
