Changes done in the ValueChangeListener is not reflecting else where

Question

Abstract:
There is an input File competent where the user can select a file to upload. The user will press a Savebutton to store file in the database.
Work Flow:
When the user select the file to upload the valueChangeListener will be called.
In the valueChangeListener I am storing the file into local variable of type UplodedFile. I am able to access all file property from this variable in the valueChangeListener; that is, I can access the file name, size,... form the local variable within the valueChangeListener.
When the user press the Save button a method to commit the changes is called.
In the commit method I am getting the file data from the local variable that hold the file data.
The problem is:
This local variable that should store the file data is always NULL. I have no idea why this variable does not contain the file data although I set its value in the valueChangeListener.
Note:
I tried to bind the input File competent to a local variable and again it gave me the same result NULL value.

Answer 1

You have to process the data inside the value change listener as it's only present during the request. The fats ids removed after the request.
Check my blog JDev11.1.2.1.0: Handling images/files in ADF (Part 2) | JDev & ADF Goodies
for a listener which processes the data directly.
