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.
