control when the create child incident button shows

[Joyce Olson]

I am working on developing major incident using Parent Child relationship.   I have created a UI Action to create a button that will create and populate a new child incident.     I have also included on the incident form a checkbox field   major_incident to identify the parent.     I want to have the Create Child Incident button display on the parent incident only but am struggling on how to accomplish this.

Shloke -

I updated my UI Action to the following and now the Create Child Incident button does not show up on any incidents.

Hey Joyce,

Sorry for not telling you this sooner, I have already answered something similar ==>

1) Create a UI Policy --> Set Condition as field (check_box) is true

2) In the Script tab set Run scripts true

3) In the if condition write      

                  $$('#action_name')[0].hide();     //This will hide the top button

                  $$('#action_name')[1].hide();     //This will hide the bottom button as well

4) In the else condition write      

                  $$('#action_name')[0].show();     //This will show the top button

                  $$('#action_name')[1].show();     //This will show the bottom button as well

you can check it over here How to hide UI Action based on field change in form without using DOM?

Nitish -   after adding the UI Policy my Create Child Incident button is showing only on Parent incidents.

Thanks for you help

By creating the UI Policy I am now able to control when the Create Child Incident buttons shows and it is working fine with the exception that when I select the checkbox Major Incident I receive the following error:

onChange script error: TypeError: $$(...)[0].Show is not a function function (){var o=i(m,arguments);return l.apply(n,o)}

Any idea how to resolve this?
