Struts2: искаженное выражение OGNL - PullRequest
2 голосов
/ 28 февраля 2012

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'

        } catch (Exception e) {
