Does the FilterExpression functionality in ListPages only work with enums?

I have created a filter field (type string) in the SalesQuotationListPage form, linked to a method in the SysQueryRangeUtil class.
The filter field receives a PurchRFQId value, and then returns a string, containing the QuotationId's that are linked to the PurchRFQId.

This is straight from the textbooks, but when ever I enter a value in the field, it either crashes or returns this error:

I have tested the method on SysQueryRangeUtil, and when I enter a PurchRFQId value, it finds the correct QuotationId, and returns this.

Any ideas if the FilterExpression only works when receiving an enums? This seems to be the case, all the places I have found, where it is used.

Found the solution myself... which was to put single quotation marks around the %1 in the FilterExpression on the filter field.

(salesQuotationListPagePurchRFQIdFilter('%1'))
