We have a link to a wiki page placed in a catalog form's onLoad attribute . Each time , the form is loaded , it will automatically open another web page specified in it . It used to work fine prior to 17.1 RU2 . After 17.1 RU2 , it no longer works .
If there is no any form component added into the form (i.e., Empty form) , it will have the issue with it . Due to some underline form implementation design change , catalog will trigger form onload only when there is at-least one field in the form (which can have any state, i..e., hidden, disabled etc.), the workaround is to add at-least an empty label component in the form for it to trigger on-load function.
ITSM catalog 17.1 RU2 , 17.2
Add at-least an empty label component in the form for it to trigger on-load function
