cdk
Tag object

Introduces new variable. Variable's scope is limited to the context of the current method, i.e. variables defined before <cdk:body> are not available after it.

Should be used within cc:implementation element.

Usage example:


Attributes
NameRequiredRequest-timeTypeDescription
nametruetruejava.lang.String

Name of the variable, corresponding to Java identifier syntax.

Examples:

  • <cdk:object name="children" ...>
  • <cdk:object name="myVariable" ...>
  • <cdk:object name="_children0" ...>
valuefalsetruejava.lang.String

EL-expression specifying initial value of the variable. If this attribute is ommitted, body of the tag is used instead.

Examples:

  • <cdk:object value="#{cc.rendered}" ...>
  • <cdk:object value="#{myObject} ...>
  • <cdk:object value="#{getSubmittedValue(facesContext, cc)} ...>
  • <cdk:object ...>#{cc.getClientId(facesContext)}</cdk:object>
typefalsetruejava.lang.String

Variable type name. CDK automatically resolves simple names for primitive types, JSF API classes and objects from java.lang.* or java.util.*. For parametrised types you can use java generics syntax

Examples:

  • <cdk:object type="java.lang.String" ...>
  • <cdk:object type="float" ...>
  • <cdk:object type="List<String>" ...>
  • <cdk:object type="UIComponent" ...>

If type is not defined explicitly, CDK will try to infer variable type from its value.
