Grails on Openshift

I created a simple Grails application which makes it possible to store client data inside a MySQL database. I created this application since I want to learn more about GORM (Grails Object Relational Mapping).

I already tested the application in the internal server from Grails, but I wanted to deploy it to a remote server. So I created a development account on Openshift and there I created the following server:

showPopupBehavior align property examples

I always struggle to understand the official descriptions for the align attribute of the af:showPopupBehavior tag. A picture is worth a thousands words so I just created screenshots of all the possible values:

afterStart: The popup appears underneath the element with the popup's upper-left corner aligned with the lower-left corner of the element. The left edges of the element and the popup are aligned


afterEnd: The popup appears underneath the element with the (more...)

Hardware is Cheap, Developers are Expensive

When advising customers on ADF projects, I often find development environments where many or all developers are working against the same database. That introduces a hard dependency between different parts of the project – if one developer deploys a defective PL/SQL package to the database, nobody else can run the application.

This approach made sense back when hardware was expensive and databases had to be managed by high priests in glass-walled, climate-controlled rooms. Today, you (more...)
