Problem with the Equals operator

Hi Team,

When I'm using a equals operator to check a null value the control goes to false even though when it is null.

The value coming out is probably not null but an empty string. You should use the StringUtils.IsNullOrEmpty method instead.

I am unable to find the function - StringUtils.IsNullOrEmpty. Where is it in PEGA and how do I access it?

I found the equals and length functions.

I need to call this in a DataTransform and when I do @equals(pyWorkPage.EmployeeName.trim(),"") , it fails

When I do @equals(pyWorkPage.EmployeeName,"") it compiles but fails at run time.

Same is the case with length functions. What am I doing wrong?
