There's been a lot of talk in the past year in regards to Liferay's new Recycle Bin framework. How do we use it? Why do we use it? Basic "user" based questions can be answered in our User Guide (Using Liferay Portal) section: Recycling Assets with the Recycle Bin. However, for a more comprehensive, in-depth guide for implementing the Recycle Bin framework for custom apps, you can now visit the Developer Guide's brand new Implementing the Recycle Bin in Your App section.
For this new Dev Guide section, we go through a detailed step-by-step guide explaining everything that is required to leverage the Recycle Bin in your personal app. Because the Recycle Bin is integrated with Liferay’s platform, configuring and implementing the Recycle Bin for your apps is easy. There are five Recycle Bin framework capabilities we discuss, in detail:
- Moving Entries to the Recycle Bin
- Restoring Entries from the Recycle Bin
- Implementing the Undo Action
- Moving/Restoring Parent Entities
- Resolving Conflicts
While discussing these capabilities, we refer to code snippets taken from Liferay’s Jukebox Portlet plugin.
If you're interested in learning about the development side of Liferay's Recycle Bin framework, the Developer Guide's new section should be your first stop!
Special thanks to Julio Camarero and Jim Hinkey, for their helpful advice and guidance.
You probably heard about the release of Liferay IDE 2.0 a couple weeks ago, but may have questions as to what is new and improved. Of course, it is compatible with the new Liferay Portal 6.2 release, but what are some of the major additions that make this release so great? The 6.1 and 6.2 Liferay Developer's Guide is now updated to describe some of these awesome new features, and also provides Liferay plugin development examples using Liferay IDE 2.0.
One of the largest additions is the brand new Liferay Plugin Project Wizard supporting both Ant (Plugins SDK) and Maven (liferay-maven-plugin) projects. This means you can now create and modify Maven projects using a graphical interface! There's also a new POM editor featuring five interactive modes, which helps you modify and organize your POM and its dependencies. Having problems resolving your POM's errors? Liferay IDE 2.0 also offers resolution generation for common pom.xml errors.
Greg Amerson wrote a couple useful blogs that introduces Liferay IDE 2.0's new features: Liferay IDE Milestone 1 Update and Liferay IDE Milestone 3 Update.
For examples and documentation on IDE's new features, visit our Working with Liferay's Developer Tools chapter in Liferay's 6.2 Developer's Guide. If you're interested in using Liferay IDE 2.0 for Liferay Portal 6.1, you can reference the Liferay IDE and Developer Studio and Developing Plugins Using Maven chapters of Liferay's 6.1 Developer's Guide. However, these aren't the only places to find IDE related information! IDE examples are sprinkled throughout the guides for most plugin development examples as well (e.g. Developing Portlet Applications chapter has IDE example for developing Liferay portlet plugins).
