Hello,
I'm new on
struts and want to handle following problem:
I am listing all the invoice items via <logic:iterate> in my invoiceList.jsp. Beside each invoice line, there is a checkbox,
which I want to use as following: User clicks on any checkbox to select the appropriate invoice item beside it, and after clicking on the submit button at the bottom, the id of the selected invoice shoould be transferred to InvoiceEditAction.editInvoice() method.
But I get following error message unfortunately:
javax.servlet.ServletException: java.lang.NumberFormatException: For input
string: ""
So I think the id can not be transferred at all.
Below you can find my invoiceList.jsp. Any help is appreciated.
<html>
<body>
<html:form action="invoiceEdit">
<table >
<tbody>
<tr>
<td></td>
<td>id</td>
<td>Invoice No</td>
<td>Date</td>
</tr>
<logic:iterate name="invoiceListForm" property="invoices" id="invoice">
<tr>
<td >
<input
type="checkbox"
value="<bean:write name="invoice" property="id"/>"
name="editInvoice">
</td>
<td><bean:write name="invoice" property="id" /></td>
<td><bean:write name="invoice" property="invoiceNo" /></td>
<td><bean:write name="invoice" property="date" /></td>
</tr>
</logic:iterate>
</tbody>
</table>
<html:button property="add"
onclick="location.href='invoiceEdit.do?do=addInvoice'">Add a new invoice
</html:button>
<html:button property="back"
onclick="location.href='default.do'">Back to menu
</html:button>
<%-- set the parameter for the dispatch action --%>
<html:hidden property="do" value="editInvoice" />
<html:submit>Update</html:submit>
