Validating flash code

This is useful as you can use the error object to restore the value input by the user using the field Value tag: Another important thing to note about errors in Grails is that error messages are not hard coded anywhere.The Field Error class in Spring resolves messages from message bundles using Grails' i18n support.So for example, if you only wanted to import the 'last Name' constraint you would use: Typically if you get a validation error you redirect back to the view for rendering. Grails supports a rich set of tags for dealing with errors.To render the errors as a list you can use render Errors: Each error is actually an instance of the Field Error class in Spring, which retains the original input value within it.The connection to the Google Analytics Tracking Code can be configured through the web property ID parameter in one of two ways: Use this mode if you control the Adobe Flash Action Script 3 code, but you do not control the hosting environment of your Adobe Flash application.For example, if you are developing Flash content for distribution across many sites, then you would use AS3 mode.Without the Google Analytics Tracking for Adobe Flash component, tracking Adobe Flash content with Google Analytics involves a number of technical hurdles. In addition, you must also anticipate whether your Flash content will have access to the browser Document Object Model (DOM), since tracking fails for those objects where access to the DOM is denied (typically when your content resides on 3rd party sites).This involves understanding how to use the call in Action Script 3 to access the browser DOM and to degrade when access is denied.

This is when Grails will validate the bound values against the constraints you defined.AS3 mode is completely independent from the tracking installation with this mode.In addition, AS3 mode uses the Flash storage mechanism to track session information for the user.The '*' constraint is a special case: it means that the associated constraints ('nullable' and 'size' in the above example) will be applied to all properties in all validateable classes.These defaults can be overridden by the constraints declared in a validateable class. Both of these accept a list of simple or regular expression strings that are matched against the property names in the source constraints.The Google Analytics for Adobe Flash component simplifies tracking your Flash content and handles DOM access gracefully.
