Whenever I am trying to create a special price for a product and try to select the from and to dates for the same the date is not getting selected at all, I have to enter it manually every time. How can I correct this?
So date fields are added using Varien_Data_Form_Element_Date. What you could do would be to look into this file and check the function getElementHtml
I did in c.e 1.8.1 and found that the z-index was empty. I'm assuming it's being attached to the dom wrong, as it's using some khtml browser speciality code. Anyways, I got it working again by adding
cal.element.style.zIndex = 99999;
