use of com.manydesigns.elements.options.SelectionProvider in project Portofino by ManyDesigns.

/**
 * Returns values to update multiple related select fields or a single autocomplete text field, in JSON form.
 * @param selectionProviderName name of the selection provider. See {@link #selectionProviders()}.
 * @param selectionProviderIndex index of the selection field (in case of multiple-valued selection providers,
 *                               otherwise it is always 0 and you can use
 *                               {@link #jsonOptions(String, String, String, boolean)}).
 * @param labelSearch for autocomplete fields, the text entered by the user.
 * @param prefix form prefix, to read values from the request.
 * @param includeSelectPrompt controls if the first option is a label with no value indicating
 * what field is being selected. For combo boxes you would generally pass true as the value of
 * this parameter; for autocomplete fields, you would likely pass false.
 * @return a Response with the JSON.
