Hello,
I want to handle following problem:
I am listing all the invoice items via <logic:iterate> in the invoiceList.jsp. In GUI, beside each invoice line, there is a checkbox pointing to this invoice. If the user clicks on a checkbox and afterwards clicks on the submit button, the id of the selected invoice should be transferred to InvoiceEditAction.editInvoice() method.
But I get following error when I do this:
javax.servlet.ServletException: java.lang.NumberFormatException: For input string: ""
I assume that the id is passed as "".
Below you can find my invoiceList.jsp. Any help is appreciated.
