-/**
- * 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.
