I am working on a realestate app, the section I am working is where an
admin converts an active listing to a sale.
The process is pretty strait forward, I take all the data from the
listing and insert it into the sale table. If the the listing has
already been converted it returns and error and does not change the
state. If there is no error, it changes teh state and populates the form
components on the edit sale screen. Everything up to the point where I
populate the form inputs works. The problem is it spits out this error,
when I convert the first listing. After I convetr the first listing, and
go to convert a second one, I no longer get this error, it changes the
state and populates like it should. I have done this with the same
record. The first time I get the error the second time I get the desired
results.
TypeError: Error #1009: Cannot access a property or method of a null
object reference.
