doesn't exist yet - for now see the Javadoc for QueryHelper.getPersistentObjects

departure-example

An example of an airport departure card.

Covers: data validation, using Group for layout, displaying dynamic images

Note: this example was actually written as a test of how productive this technology is.  The author wrote the rules in 1 hour and then a UI developer (who doesn't know the underlying technology) spent another 1 hour making it look nice using CSS.  The example (and the original paper version from which it was modelled) includes 5 separate branching points.

genealogy-example

A simple family tree example.

Covers: multiple copies of the same question with different ids, custom javascript to present a boolean question as an icon.

loyalty-card-examples

3 examples of increasing complexity which build up a ficticious Solnet Loyalty Card.

• simple - single page with some dynamic behaviour
• medium - multiple pages and more dynamic behaviour, multiple skins/brands using different CSS on the same rules, custom javascript to present a note as a progress bar
• complex - joint account (reuse of question rules), other loyalty programs (page branching), custom answerType to aid validation, readonly questions
• complete - it would be nice to extend this into a compete end-to-end working application by adding persistence so you can enter your name and it opens your record allowing you to edit the fields (but perhaps with some readonly).

SpreadsheetBiology and SpreadsheetLoyaltyGold

These two examples demonstrate how to use tohu-loader to generate drl files from an Excel spreadsheet.

The readme.txt file explains how to enable auto-reloading of the rules if the spreadsheet is edited.

liferay-example

This example shows how to use Tohu within a JSR-286 portlet that runs on Liferay.
