When using themes you want to changes some of the translations specifically to the theme while keeping the standard translations for most of the text.
Duplicating the main translation file is a headache for maintainance.
This how to provides a solution.
Clearing CGridView filters and sort orders from the web pages, is usefull for the end user. Yii does not seem to propose a standard method. Furthermore, this is especially usefull when filters are "remembered" in the user's session.
A dropdown list can be used to select a value, based on which we can filter the data to be displayed. For example, the extension page has a dropdown list to filter the displayed extensions according to the selected category.
The number of languages supported by the standard CJuiDatePicker implementation is limited and the language code to use is different from the application's language code.
This Wiki shows how to improve on that.
