Why wont BLOBS commit in forms

Question

I used read-image-file in a 'When-image-pressed' trigger to insert the image. It did'nt work with message '47100 - Cant read image file ...'. I noticed other images in the example tables where all around 100k so i resized mine from 900k to 100k and tried again and it worked and committed but it still wouldnt return the image in a query. I then loaded the image through a procedure using DBMS_LOB and then queried the record in Forms and it worked. So
Why wouldnt the larger image work, i thought blobs were up to 4gb and
Why is Forms not commiting the image to the database
Anyone more answers or ideas?

Answer 1

While you can use DML statements from triggers (and 6i obviously treats them more logically than 4.5), Forms is structured more towards making DML changes through blocks - that is, you type the new record into the block and when you save the form it gets written into the database as an insert.
Rather than writing to global variables and adding code to the first block's on-update, you could write the record you want insert to a hidden block based on the appropriate table, so that it fits within the "normal" forms DML structure.
I don't know whether these being committed is considered a bug, but bear in mind that Forms 4.5 as a product is getting VERY old. I haven't used it since some Oracle Apps 10.7 work something like seven years ago.
