Page Initialization
From Documentation
Sometimes it is helpful to run some code before ZK Loader instantiates any component. For example, check if the user ha the authority to access, initialize some data, or prepare some variables for EL expressions[1].
This can be done easily by implementing Initiator, and then specifying it with the init directive.
<?init class="com.foo.MyInitial"?>
A typical use of the init directive is to specify a data binder, as shown below.
<?init class="org.zkoss.zkplus.databind.AnnotateDataBinderInit"?>The data binder will parse all annotations and bind the data according to the annotations, after all components in a ZUML document is instantiated.
- ↑ The preparation of variables for EL expression is generally better to be done in the constructor of VariableResolver (and specified with the variable-resolver directive.
