Calender not getting displayed after modified input field


I am attaching calendar to an input field. It gets initialized and displayed correctly until certain parameters are changed for the input field.
We are validating user enetered string, if the validation fails we change the css class for the input field( to which calendar has been attached). We also add a tooltip. After this when I click the input field again, calendar is not getting displayed.
On error condition we are aslo adding few divs on top of the page with messages. could this be an issue.
