 /**

- * Prado client-side javascript validation manager.

+ * Prado client-side javascript validation fascade.

+ * 

+ * There are 4 basic classes, Validation, ValidationManager, ValidationSummary

+ * and TBaseValidator, that interact together to perform validation.

+ * The <tt>Prado.Validation</tt> class co-ordinates together the 

+ * validation scheme and is responsible for maintaining references

+ * to ValidationManagers. 

+ * 

+ * The ValidationManager class is responsible for maintaining refereneces

+ * to individual validators, validation summaries and their associated

+ * groupings.

+ * 

+ * The ValidationSummary take cares of display the validator error messages

+ * as html output or an alert output. 

+ * 

+ * The TBaseValidator is the base class for all validators and contains

+ * methods to interact with the actual inputs, data type conversion.

+ * 

+ * An instance of ValidationManager must be instantiated first for a

+ * particular form before instantiating validators and summaries.

+ * 

+ * Usage example: adding a required field to a text box input with 

+ * ID "input1" in a form with ID "form1".

+ * <code>

+ * <script type="text/javascript" src="../prado.js"></script>

+ * <script type="text/javascript" src="../validator.js"></script>

+ * <form id="form1" action="...">

+ * <div>

+ * 	<input type="text" id="input1" />

+ *  <span id="validator1" style="display:none; color:red">*</span>

+ *  <input type="submit text="submit" />

+ * <script type="text/javascript">

+ * new Prado.ValidationManager({FormID : 'form1'});

+ * var options = 

+ * {

+ *		ID :				'validator1',

+ *		FormID :			'form1',

+ *		ErrorMessage :		'*', 

+ *		ControlToValidate : 'input1'

+ *	}

+ * new Prado.WebUI.TRequiredFieldValidator(options);

+ * new Prado.WebUI.TValidationSummary({ID:'summary1',FormID:'form1'});

+ * 

+ * //watch the form onsubmit event, check validators, stop if not valid.

+ * Event.observe("form1", "submit" function(ev)

+ * {

+ * 	 if(Prado.WebUI.Validation.isValid("form1") == false)

+ * 		Event.stop(ev);

+ * });

+ * TListControlValidator class.

+ * 

+ * TListControlValidator checks the number of selection and their values

+ * for a <b>TListControl that allows multiple selection</b>. 

+ *

+ * You can specify the minimum or maximum (or both) number of selections

+ * required using the {@link setMinSelection MinSelection} and

+ * {@link setMaxSelection MaxSelection} properties, respectively. In addition,

+ * you can specify a comma separated list of required selected values via the

+ * {@link setRequiredSelections RequiredSelections} property.

+ *

+ * Examples

+ * - At least two selections

+ * <code>

+ *	<com:TListBox ID="listbox" SelectionMode="Multiple">

+ *		<com:TListItem Text="item1" Value="value1" />

+ *		<com:TListItem Text="item2" Value="value2" />

+ *		<com:TListItem Text="item3" Value="value3" />

+ *	</com:TListBox>

+ *

+ *	<com:TRequiredListValidator 

+ *		ControlToValidate="listbox"

+ *		MinSelection="2" 

+ *		ErrorMessage="Please select at least 2" />

+ * </code>

+ * - "value1" must be selected <b>and</b> at least 1 other

+ * <code>

+ *	<com:TCheckBoxList ID="checkboxes">

+ *		<com:TListItem Text="item1" Value="value1" />

+ *		<com:TListItem Text="item2" Value="value2" />

+ *		<com:TListItem Text="item3" Value="value3" />
