Возможно ли использовать RestyGwt и GWT Material Design вместе?

0 голосов
/ 18 апреля 2019

Я настраиваю новый проект и хочу использовать RestyGwt и Gwt Material Design вместе, но когда я добавляю RestyGWT в модуль GWT, я получаю ClassCastException на стороне клиента.

Я попытался понизить версию GWT Material Design до версии 2.0 и добавить следующие строки в модуль GWT и пом. 

<inherits name="com.google.gwt.user.theme.clean.Clean" />
<inherits name="com.github.nmorel.gwtjackson.GwtJackson" />

<dependency>
    <groupId>com.github.nmorel.gwtjackson</groupId>
    <artifactId>gwt-jackson</artifactId>
    <version>0.14.2</version>
</dependency>

ClassCastException не связано с классом Person. Та же проблема возникает, когда я добавляю пустой MaterialDataTable (или другие более сложные компоненты, чем кнопка или метка) для RootPanel.
