I am creating recordlist from the result of an aggregate. For that I am iterating through foreach loop of result set of an aggregate.
I am getting this error.
This is the logic
Thanks and Regards,
I am guessing you trying to append record in list which you are using in for-each loop.
If still problem not solved please attach oml.
If you are trying to append\remove a record in the same list you are iterating on it will give you error and this is because the length of the list has decided when you start the iteration .
Yeah, what Sashi and Pramod said. Mutating a list you're iterating over is not possible, for obvious reasons. What were you tring to do? I can't think of many use cases that would be in need for modifying a list you're iterating. If you do have a good use case, first ListDuplicate the list, then Append to the duplicated list.
