Hello
I have the following error when i run some code in the expression builder of tMap
Exception in thread "main" java.lang.Error: Unresolved compilation problems:
this is my code, can anyone help?
while (StringHandling.LEN("row2.id") != Var.MaxLen)
{
row2.updatedID ="0" + row2.id ;
}

row2.id=string
var.MaxLen=int
row2.updatedId=string

Hi
Try this expression in the expression field of column:
StringHandling.LEN(row2.id)==Var.MaxLen?row2.id:"0"+row2.id
Best regards

just realised that my code doesnt make sense.
it should be
(i am trying to make ids all with the same length)
row2.updatedID=row2.id;
while (StringHandling.LEN("row2.updatedId") < Var.MaxLen)
{
row2.updatedId ="0" + row2.updatedId ;
}

however i am still having errors

Can you please show us your expression? If you want to achieve some if...else statement in tMap, you have to use the following expression format:
condition?value if true: value if false
