The Asset Picker is the mechanism that the Business Control Center provides to allow users to search or browse for assets. It is presented whenever users need to choose an asset—for example, when they select the Add Asset to Project option in the Assets tab or specify an asset as the target of a link from another asset. The Asset Picker is also used as the starting point for creating several types of assets.
The Asset Picker is extensible, allowing you to add custom plugin components that support asset search or browse functionality for custom asset types.
The Asset Picker consists of the following pieces:
A set of JSPs that provide the base-level pages of the Asset Picker and function as a container for the plugin search or browse components. The default pages are packaged in the
AssetUI.warfile in<ATG10dir>\AssetUI\j2ee-apps\assetUI.ear.Container JavaScript API: an API implemented by the container pages that is accessed by the plugin page and returns information on the specific asset type included in the search.
Plugin JavaScript Interface: an API implemented by the plugin page and called by the container page to communicate with the Asset Picker plugins.
Client JavaScript API: an API implemented by the Business Control Center. It is used to determine the possible asset types selectable by the picker, to configure its many options, and to invoke it.
Items in the View Mapping repository, which determine the appropriate plugin to present to the user.
JSPs that represent the plugin components. Default plugins are provided for repository search, virtual file system search, and virtual file system browse.
You can change the default tab that is presented to users when they open the Asset Picker. To do so, edit the assetPickerDefaultView property in the /atg/web/assetmanager/Preferences component. Possible values are Search, Browse, or the display name of any custom asset picker tabs you have added to your environment. (Specifically, the value you enter is the defaultValue in the itemViewAttributeDefinition configured for the tab’s display name.) If no value is set, the Browse tab is displayed.
