我有这个错误。

javax.el.ELException: Cannot convert false of type class java.lang.String to class com.vocabase.objects.dialog.modules.Module
at org.apache.el.lang.ELSupport.coerceToType(ELSupport.java:553)

关于此代码。

                                        <c:otherwise>false</c:otherwise>
                                    </c:choose>
                                </c:set>
                            <%}%>
                        </c:when>...

好的错误是

<c:choose>
    <c:when test="${tmp.value=='on' }">true</c:when>
    <c:otherwise>false</c:otherwise>
</c:choose>

我不知道如何修复它。错误发生在带有tomcat 8.5的java 8上，它是项目形式java 6的更新，其中包含tomcat 6。我需要一些想法，因为我尽可能地尝试但错误就在那里。

谢谢你，维拉德。

我该如何解决这个无法转换错误？
