Hi,
I have a rule input called ri!state which gets its value from a query rule. Then I am passing this rule input to the value and saveInto fields of a textbox like this:

a!textField(
label:"State",
value:ri!state,
saveInto:ri!state)

I am getting an error called "Cannot save type List of Text into Text". The only way I found to solve this problem is by passing null to saveInto field. Is there a way around to solve this problem and why I am getting this error?
thanks...

Query rules return an array of items; even if there's only result the return type will be a list of items with a single item inside.

If you are expecting a single value use the index() function to retrieve the first value of the query rule's array.
