value

Class: com.microstrategy.web.app.taglibs.ValueTag

Usage:

This tag retrieves the value of the a preference or a configuration parameter or an enumeration or from the request keys.
The place from where the value will be retrieved will be specified in the type attribute of this tag. The name is specified in the name attribute of this tag. There is an optional attribute named as attribute which will append any text specified here before rendering the actual value. If this attribute is present, we will render the actual value within a double quote and an equals to sign after the attribute.For example, the following snippet shows how the value tag is used to extract the actual value of a constant. This would render the "~" character as this is the specified value for this constant: 
 <web:value type="enum" name="com.microstrategy.web.app.utils.ExpressionHelper.ITEM_SEPARATOR" />
In other cases, developers may want to use the value tag in conjunction with other HTML tags to generate dynamic output. For example, the following snippet would generate an anchor tag where the “HREF” attribute would be set to the name of the Admin Servlet: 
 <A <web:value name="adminServletDeploymentName" type="config" attribute="HREF" /> >[Go to the Web Administrator]</A>
