-/**

- * TAutoComplete class.

- *

- * TAutoComplete is a textbox that provides a list of suggestion on

- * the current partial word typed in the textbox. The suggestions are

- * requested using callbacks, and raises the {@link onSuggestion OnSuggestion}

- * event. The events of the TActiveText (from which TAutoComplete is extended from)

- * and {@link onSuggestion OnSuggestion} are mutually exculsive. That is,

- * if {@link onTextChange OnTextChange} and/or {@link onCallback OnCallback}

- * events are raise, then {@link onSuggestion OnSuggestion} will not be raise, and

- * vice versa.

- *

- * The list of suggestions should be set in the {@link onSuggestion OnSuggestion}

- * event handler. The partial word to match the suggestion is in the

- * {@link TCallbackEventParameter::getCallbackParameter TCallbackEventParameter::CallbackParameter}

- * property. The datasource of the TAutoComplete must be set using {@link setDataSource}

- * method. This sets the datasource for the suggestions repeater, available through

- * the {@link getSuggestions Suggestions} property. Header, footer templates and

- * other properties of the repeater can be access via the {@link getSuggestions Suggestions}

- * property and its sub-properties.

- *

- * The {@link setTextCssClass TextCssClass} property if set is used to find

- * the element within the Suggestions.ItemTemplate and Suggestions.AlternatingItemTemplate

- * that contains the actual text for the suggestion selected. That is,

- * only text inside elements with CSS class name equal to {@link setTextCssClass TextCssClass}

- * will be used as suggestions.

- *

- * To return the list of suggestions back to the browser, supply a non-empty data source

- * and call databind. For example,

- * <code>

- * function autocomplete_suggestion($sender, $param)

- * {

- *   $token = $param->getToken(); //the partial word to match

- *   $sender->setDataSource($this->getSuggestionsFor($token)); //set suggestions

- *   $sender->dataBind();

- * }

- * </code>

- *

- * The suggestion will be rendered when the {@link dataBind()} method is called

- * <strong>during a callback request</strong>.

- *

- * When an suggestion is selected, that is, when the use has clicked, pressed

- * the "Enter" key, or pressed the "Tab" key, the {@link onSuggestionSelected OnSuggestionSelected}

- * event is raised. The

- * {@link TCallbackEventParameter::getCallbackParameter TCallbackEventParameter::CallbackParameter}

- * property contains the index of the selected suggestion.

- *

- * TAutoComplete allows multiple suggestions within one textbox with each

- * word or phrase separated by any characters specified in the

- * {@link setSeparator Separator} property. The {@link setFrequency Frequency}

- * and {@link setMinChars MinChars} properties sets the delay and minimum number

- * of characters typed, respectively, before requesting for sugggestions.

- *

- * Use {@link onTextChange OnTextChange} and/or {@link onCallback OnCallback} events

- * to handle post backs due to {@link setAutoPostBack AutoPostBack}.

- *

- * In the {@link getSuggestions Suggestions} TRepater item template, all HTML text elements

- * are considered as text for the suggestion. Text within HTML elements with CSS class name

- * "informal" are ignored as text for suggestions.

+/**
+ * TAutoComplete class.
+ *
+ * TAutoComplete is a textbox that provides a list of suggestion on
+ * the current partial word typed in the textbox. The suggestions are
+ * requested using callbacks, and raises the {@link onSuggestion OnSuggestion}
+ * event. The events of the TActiveText (from which TAutoComplete is extended from)
+ * and {@link onSuggestion OnSuggestion} are mutually exculsive. That is,
+ * if {@link onTextChange OnTextChange} and/or {@link onCallback OnCallback}
+ * events are raise, then {@link onSuggestion OnSuggestion} will not be raise, and
+ * vice versa.
+ *
+ * The list of suggestions should be set in the {@link onSuggestion OnSuggestion}
+ * event handler. The partial word to match the suggestion is in the
+ * {@link TCallbackEventParameter::getCallbackParameter TCallbackEventParameter::CallbackParameter}
+ * property. The datasource of the TAutoComplete must be set using {@link setDataSource}
+ * method. This sets the datasource for the suggestions repeater, available through
+ * the {@link getSuggestions Suggestions} property. Header, footer templates and
+ * other properties of the repeater can be access via the {@link getSuggestions Suggestions}
+ * property and its sub-properties.
+ *
+ * The {@link setTextCssClass TextCssClass} property if set is used to find
+ * the element within the Suggestions.ItemTemplate and Suggestions.AlternatingItemTemplate
+ * that contains the actual text for the suggestion selected. That is,
+ * only text inside elements with CSS class name equal to {@link setTextCssClass TextCssClass}
+ * will be used as suggestions.
+ *
+ * To return the list of suggestions back to the browser, supply a non-empty data source
+ * and call databind. For example,
+ * <code>
+ * function autocomplete_suggestion($sender, $param)
+ * {
+ *   $token = $param->getToken(); //the partial word to match
+ *   $sender->setDataSource($this->getSuggestionsFor($token)); //set suggestions
+ *   $sender->dataBind();
+ * }
+ * </code>
+ *
+ * The suggestion will be rendered when the {@link dataBind()} method is called
+ * <strong>during a callback request</strong>.
+ *
+ * When an suggestion is selected, that is, when the use has clicked, pressed
+ * the "Enter" key, or pressed the "Tab" key, the {@link onSuggestionSelected OnSuggestionSelected}
+ * event is raised. The
+ * {@link TCallbackEventParameter::getCallbackParameter TCallbackEventParameter::CallbackParameter}
+ * property contains the index of the selected suggestion.
+ *
+ * TAutoComplete allows multiple suggestions within one textbox with each
+ * word or phrase separated by any characters specified in the
+ * {@link setSeparator Separator} property. The {@link setFrequency Frequency}
+ * and {@link setMinChars MinChars} properties sets the delay and minimum number
+ * of characters typed, respectively, before requesting for sugggestions.
+ *
+ * Use {@link onTextChange OnTextChange} and/or {@link onCallback OnCallback} events
+ * to handle post backs due to {@link setAutoPostBack AutoPostBack}.
+ *
+ * In the {@link getSuggestions Suggestions} TRepater item template, all HTML text elements
+ * are considered as text for the suggestion. Text within HTML elements with CSS class name
+ * "informal" are ignored as text for suggestions.

- * TCallbackClientScript class.

- *

- * The TCallbackClientScript class provides corresponding methods that can be

- * executed on the client-side (i.e. the browser client that is viewing

- * the page) during a callback response.

- *

- * The avaiable methods includes setting/clicking input elements, changing Css

- * styles, hiding/showing elements, and adding visual effects to elements on the

- * page. The client-side methods can be access through the CallbackClient

- * property available in TPage.

- *

- * For example, to hide "$myTextBox" element during callback response, do

- * <code>

- * $this->getPage()->getCallbackClient()->hide($myTextBox);

- * </code>

- * TCallbackClientSide class.

- *

- * The following client side events are executing in order if the callback

- * request and response are send and received successfuly.

- *

- * - <b>onPreDispatch</b> executed before a request is dispatched.

- * - <b>onUninitialized</b> executed when callback request is uninitialized.

- * - <b>onLoading</b>* executed when callback request is initiated

- * - <b>onLoaded</b>* executed when callback request begins.

- * - <b>onInteractive</b> executed when callback request is in progress.

- * - <b>onComplete</b>executed when callback response returns.

- * - <b>onSuccess</b> executed when callback request returns and is successful.

- * - <b>onFailure</b> executed when callback request returns and fails.

- * - <b>onException</b> raised when callback request fails due to request/response errors.

- *

- * * Note that theses 2 events are not fired correctly by Opera. To make

- *   them work in this browser, Prado will fire them just after onPreDispatch.

- * 

- * In a general way, onUninitialized, onLoading, onLoaded and onInteractive events 

- * are not implemented consistently in all browsers.When cross browser compatibility is

- * needed, it is best to avoid use them

- *

- * The OnSuccess and OnFailure events are raised when the

- * response is returned. A successful request/response will raise

- * OnSuccess event otherwise OnFailure will be raised.

- *

- * - <b>PostState</b> true to collect the form inputs and post them during callback, default is true.

- * - <b>RequestTimeOut</b> The request timeout in milliseconds.

- * - <b>HasPriority</b> true to ensure that the callback request will be sent

- *   immediately and will abort existing prioritized requests. It does not affect

- *   callbacks that are not prioritized.

- * - <b>EnablePageStateUpdate</b> enable the callback response to enable the

- *   viewstate update. This will automatically set HasPriority to true when enabled.

- * is true and the textbox content has changed, a callback request is made and

- * After the callback request returns sucessfully, the textbox is enabled.

- * If the {@link setAutoHideTextBox AutoHideTextBox} property is true, then
