formapi

System

Hi, I am using formapi to validate dates on 'onsave' event. Validation is happening, but after the alert message, getting http 500 error page in the top portion of the dct (where all links like save, save as, preview, generate) are there. I am not able to use 'onchangeitem' because i am using cgi-callout for calender to populate the date fields. Can anyone suggest me on this? thanks.
