How to do empty list check in maximo anywhere

Question

Answer 1

We can do a empty check for list as below if(list && list!="-@@EmptyComplexField@@-")

Answer 2

Not sure why you're getting this EmptyComplexField string down at your layer. Are you sure you've defined your multiplicity correctly on the OSLC Resources app for these new children objects?

if (/-or-many$/.test(complexAttribute.multiplicity)){
                var attributeName = complexAttribute.remoteName;
                if (!(attributeName in data)){

Are you making sure these complexattributes are set as requiredattributes on the view before you display it?

Answer 3

The most correct answer would be:

if (list && list != PlatformConstants.EMPTY_COMPLEX_FIELD) { ... }
