Question

Before I start writing custom methods for it are there any coldbox validation aficionados out there who can help with some requiredIf array constraint logic Details in the thread

Basically I have two properties in a bean that are both arrays and at least one of them needs to be required If either is provided then the other shouldn t be required both can be provided of course I thought that might look something like this ```this constraints append array1 requiredIf array2 nullValue array2 requiredIf array1 nullValue ``` But if I populate it with the following and validate it ` array1 1 2 3 ` I get an exception form the validation module ```lucee runtime exp ExpressionException can t compare Complex Object Type Array with a String at lucee runtime type util ArraySupport compareTo ArraySupport java 290 at lucee runtime op Operator compare Operator java 202 at lucee runtime op Operator compare Operator java 74 at models validators requiredifvalidator cfc$cf$49 udfCall cbvalidation models validators RequiredIfValidator cfc 57 at ```

I ve only used cb validation a couple times and it has always been with simpler values constraints I guess

I am using cbvalidation a lot but never used requiredUnless but think you need requiredUnless e g ```this constraints append array1 requiredUnless array2 array2 requiredUnless array1 ```

If you look at the RequiredIf and RequiredUnless constraints you will see they come in two formats one where the other field has an exacct value and one where you just have to enter the name of this field In the latter case it just checks if this second field is not empty I guess that s what you want

if you need something more complex you probably need an UDF or a CustomValidator Just let me know if you need them it is actually quite easy to create one so I can give you some pointers

well that was easy enough requiredUnless instead of requiredIf
