org.apache.jasper.JasperException: /WEB-INF/views/modules/goodMan/orderList.jsp (line: [30], column: [82]) Attribute qualified names must be unique within an element

Cause: The tag attributes repeat!

For example, here is my error:

The third line below, I was careless <form: form> tag written two action attribute, it will prompt: Attribute qualified names must be unique within an element

Wherein the element refers <form: form> and Attribute refers action    

 

 

<div class="tab_pane fade in active" id="showList">
        <form:form action="searchForm" modelAttribute="order" action="${ctx}/sys/order/" method="post" class="breadcrumb form search">
        <ul class="ul-form">
            <li>
                <label for="> Order number </ label>"orderId
                <form:input path="orderId" htmlEscape="false" maxlength="15" class="input-medium"/>
            </li>

                <form:input path="shopperName" htmlEscape="false" maxlength="15" class="input-medium"/>
            </li>
            <%-- <li>
                <label for="saleTime">交易时间</label>
                <form:input path="saleTime" htmlEscape="false" maxlength="15" class="input-medium"/>
            </li> --%>
        
        </ul>
        <li class="btns"><input id="btnSubmit" class="btn btn-primary" type="submit" value="查询"></li>
                <li class="clearfix"></li>
        </form:form>

After correction

<div class="tab_pane fade in active" id="showList">
        <form:form id="searchForm" modelAttribute="order" action="${ctx}/sys/order/" method="post" class="breadcrumb form search">
        <ul class="ul-form">
