Training

Hi,

i am working on the data queries and widgets II exercise, when i doing page 33, part f.

When i try to add filter (MovieGenreId = NullIdentifier() or Movie.GenreId = MovieGenreId),

It has an error, said MovieGenreId is unknow object

I have create a combo box and it's variable MovieGenreId On Part 4.

So how can i fixed it ?

Thank you.

Hi Eva,

I'm guessing it is a simple problem where you typed MovieGenreId instead of Movie.GenreId. Let me know if this helped.

Thanks

HI Charles,

when i swsp it, it does not show any error, but however i open on the browser, use filter to chose the movie genre, its does not working.

The filter setting does not working ?

Hi eva,

Im guessing you are using a drop down to filter the movie listing. And i guess the functionality is to show the whole record when the movie genre in null.

If this is the try using the following filter

Movie.GenreId = MovieGenreId or IntergerTOText(MovieGenreId) like "%" + if(MovieGenreId = NullIdentifier(), "", "NULL") + "%"

Hi Eva,

Is the variable MovieGenreId set to be of type Genre Identifier?

Best regards,

Ricardo
