File Chooser builder inputs

Table 1. General Inputs

Input name	Description
Name	Name for this builder call. The WebSphere Portlet Factory Designer displays this name in the builder call list.
Page Location	Page or pages on which this builder call acts. Alternatively, you can type in the page location syntax directly.
Starting Directory	This directory defaults to WEB-INF/models. Specify a fully qualified server path. If the path is relative, the path to the IBM® WebSphere Portlet Factory servable content root directory gets prepended to the value. The WebSphere Portlet Factory servable content root is the directory on the application server to which you installed the WebSphere Portlet Factory. Use a forward slash (/) to signify the WebSphere Portlet Factory servable content root directory in any values you specify for this input. For example, to specify the WebSphere Portlet Factory servable root directory as the File Chooser starting directory, enter / as the Starting Directory input.
Filter Class	Defaults to the following value. com.bowstreet.webapp.methods.FileChooserMethods$FilterModel This class enables files ending with .model and directories to be displayed. The com.bowstreet.webapp.methods.FileChooserMethods$FilterDirectories class enables only directories to be displayed. You can provide additional filter classes to filter any file type.
Selected Value	The name of the file or directory that is to be initially selected. The selected value is now relative to the starting directory, and the builder only displays files under the starting directory. For example: factory/core/database_services.model where WEB-INF/models is specified as the starting directory. You can type a value or an indirect reference to a value. For example: ${Variables/selectedValue}
Depth	Defaults to 99. The maximum number of directory levels to be displayed. You can type a value or an indirect reference to a value, for example: ${Variables/depthValue}
Refresh Interval (seconds)	Defaults to 3600 seconds. It is the amount of time that should elapse before recalculating the directory list.
Visible Root Node	Select this option to show the root node. For example, assume you have WEB-INF/models as the starting directory. If you select this option, the models directory appears in the tree.
Selection Rule	Select one of the following options for selection rules: All nodes can be selected Enables a user to select any item in the tree. Only leaf nodes can be selected Disables the ability to select directories. You might want to select this option if the Web page requires that a file be selected and not a directory. No Selection – Tree does not return a value Disables the ability to select any items in the tree. Such a tree is often used for display purpose to indicated hierarchical relationships among items.
