How to force Cascading Dropdown box to refresh

[Elderberg]

I'm having trouble getting a cascading dropdown to refresh programatically :

I have two fields: Field1 (dropdown) and Field2(cascading dropdown), when the page loads I can using javascript set the value of Field1, but the corresponding Field2 does not recalculate.   its always stuck filtering off the first item in the Field1  dropdown.

I resolved a way to trigger an onchange event on Field1 programmatically.  Once the onchange event is triggered the cascading dropdown refreshes properly.

var e = document.querySelector("[id*=cbParamVirtual40]");
e.dispatchEvent(new Event('change'));

Hi @Elderberg,

I know this is a couple years too late but thanks for posting this--it's extremely helpful in dealing with cascading dropdowns.
