Description

To debug javascript errors set the "debug" attribute to true, which will display Dojo (and Struts) warning and error messages at the bottom of the page. Core Dojo files are by default compressed, to improve loading time, which makes them very hard to read. To debug Dojo and Struts widgets, set the "compressed" attribute to true. Make sure to turn this option off before moving your project into production, as uncompressed files will take longer to download.

For troubleshooting javascript problems the following configuration is recommended:

  <sx:head debug="true" cache="false" compressed="false" />

Dojo files are loaded as required by the Dojo loading mechanism. The problem with this approach is that the files are not cached by the browser, so reloading a page or navigating to a different page that uses the same widgets will cause the files to be reloaded. To solve this problem a custom Dojo profile is distributed with the Dojo plugin. This profile contains the files required by the tags in the Dojo plugin, all in one file (524Kb), which is cached by the browser. This file will take longer to load by the browser but it will be downloaded only once. By default the "cache" attribute is set to false.

Some tags like the "datetimepicker" can use different locales, to use a locale that is different from the request locale, it must be specified on the "extraLocales" attribute. This attribute can contain a comma separated list of locale names. From Dojo's documentation:

The locale is a short string, defined by the host environment, which conforms to RFC 3066 (http://www.ietf.org/rfc/rfc3066.txt) used in the HTML specification. It consists of short identifiers, typically two characters long which are case-insensitive. Note that Dojo uses dash separators, not underscores like Java (e.g. "en-us", not "en_US"). Typically country codes are used in the optional second identifier, and additional variants may be specified. For example, Japanese is "ja"; Japanese in Japan is "ja-jp". Notice that the lower case is intentional – while Dojo will often convert all locales to lowercase to normalize them, it is the lowercase that must be used when defining your resources.

The "locale" attribute configures Dojo's locale:

"The locale Dojo uses on a page may be overridden by setting djConfig.locale. This may be done to accomodate applications with a known user profile or server pages which do manual assembly and assume a certain locale. You may also set djConfig.extraLocale to load localizations in addition to your own, in case you want to specify a particular translation or have multiple languages appear on your page."

To improve loading time, the property "parseContent" is set to false by default. This property will instruct Dojo to only build widgets using specific element ids. If the property is set to true Dojo will scan the whole document looking for widgets.

Dojo 0.4.3 is distributed with the Dojo plugin, to use a different Dojo version, the "baseRelativePath" attribute can be set to the URL of the Dojo root folder on your application.
