Convert Text Array to datasubset

I'm trying to covert an array of text to datasubset to display in a paging grid, but when applying the todatasubset function to this array an error message pops up saying "The given data type is not a complex type" even though it says that the arrayToPage parameter can be of simple or complex type. Is there any workaround to be able to page an array of text in a gridField?
