I have problem with the smallicons property in Unilistview when I try to assign it to an imagelist.

Here's the affected line:

lstFile.smallicons = Imagelist1

where lstFile is unilistview and Imagelist1 is an Imagelist. When running the program it throws an error that says object or variable is not initialized. This problem don't exist when lstFile is ListView type. I have tried changing various views and it still doesn't work. Any idea?
