It’s here! Oracle Application Express 4.0 Early Adopter is available at http://tryapexnow.com/ hosted on the Amazon Elastic Compute Cloud. We are really looking forward for your feedback! I’m especially interested in the new tree, plug-ins, Advisor, Application Search, Required Flag, Sub Regions, Textfield with autocomplete, Rich Text Editor, … just to name a few : -)
Oh, by the way. Check out my Plug-in Sample Application which contains many plug-ins I have written. It should give you an idea how the plug-in code should look like. “Get Data” for example is a more complicated one, but get started with “Masked Text Field” first. I try to post some tutorials soon.
