Java Assert

The assert keyword is mainly used for unit testing, enabling you to test variable (value) assumptions of your program during runtime. Assert checking could be enabled by configuring "-ea" on VM options - otherwise assert statements would be ignored. With the use of assert, you will be able to pin point potential bugs faster.

In practice I don't often use assert; so prolly I'm writing this entry to change that.

GL Super User contained it ~ not sure though if this is a custom responsibility or not.

parent parameter value set:

second parameter value set:

OAF File Upload

I tried to utilize an attachment image component as an attempt to work on a file upload function (because of the word "attachment") but failed miserably XDww Second attempt was with messageFileUpload component and yeah I finally got it right this time.

The only thing you need to take note is to link the component with a ViewObject attribute - which value will be used as a reference to retrieve the file for later viewing.

A null reference value will render the textfield + browse button combo, while a non-null value will render a view hyperlink and a clear button (which removes the reference value from the attribute)
