В моих JSP я использую плагин с именем TagEdit , он должен иметь текстовое поле ввода с "name = 'tag []'", как показано ниже:
<s:form theme="simple" action="myActionn" method="post">
<s:textfield theme="simple" name="tag[]" value="" cssClass="tag"/>
<sj:submit targets="actionMessageResult"/>
</s:form>
Но когда я отправляю его, struts2 выдает это исключение:
WARNING: Error setting expression 'tag[]' with value '[Ljava.lang.String;@6c2a78'
