When using the latest stable jQuery UI themes (1.8.10) with Yii 1.1.6 (which uses 1.8.6) the widgets don't appear (they're invisible but they're there). In order to make them visible you need to change the following line:

First param in CActiveDataProvider could be a string with model name or instance of class. So, you may use CActiveRecord::cache() for cache, but you need set third param to 2, because you should cache 2 queries: counting and get data.

My article Display the full record in a CJuiDialog uses ajax to view a record in dialog on clicking the 'view-icon'.

Suppose to have two models: Users and Emails. You do not want to store email in a Users model. And User can have 0 or many emails. This is the form generated to create a new user (just username).
