Hi,
I am trying to submit a list of 'CustomerDetailsDTO' bean comprising attributes ie. name, address in 'CustomerDetailsForm' using the following code. My form CustomerDetailsForm.getListCustomerDetails() method returns me the list of POJOs of CustomerDetails dto

<html:select name="CustomerDetailsForm" property="listCustomerDetails" onchange="submit()"> <bean:define name="CustomerDetailsForm" property="listCustomerDetails" id="list2" /> <!-- html:optionsCollection value="address" label="address" name="CustomerDetailsForm" property="listCustomerDetails"/--> <html:options collection="list2" property="address" /> </html:select>

Everything goes fine and the page gets loaded but when i click on submit it gives me the exception.
java.lang.IllegalArgumentException: Cannot invoke forms.CustomerDetailsForm.setListCustomerDetails - argument type mismatch at org.apache.commons.beanutils.PropertyUtilsBean.invokeMethod(PropertyUtilsBean.java:1778) at org.apache.commons.beanutils.PropertyUtilsBean.setSimpleProperty(PropertyUtilsBean.java:1759)
I experimented the similar thing but there it was String[] as form field. In the above code i need to iterate through the pojo objects stored as elements in list.
I w'ld appreciate if somebody can help.
Thanks in advance

Hi,
I have got the solution to the above problem,but wonder that the pojo object's fields must be of String type to work correctly if not using any other custom tag.

The modified code is :

thanks
<html:form action="/getAllSourceTableNames">
	<script>
		function handleEvent(elem){
			alert(' text ' + elem.options[elem.selectedIndex].text);
			document.getElementById("selectedRecord").value = elem.options[elem.selectedIndex].text ;
			document.forms[0].submit();
		}
	</script>
 
	<logic:empty name="ClientTableDetailsForm" property="sourceTableList">
		No Records Found !
	</logic:empty>
	
	<bean:define id="preSelectedRecord" name="ClientTableDetailsForm" property="selectedRecord" type="String"/>
	<br>
	<logic:notEmpty id="stl" name="ClientTableDetailsForm" property="sourceTableList">
		<%= "Length is greater than zero" %>
		<p/>
		<html:select name="ClientTableDetailsForm" property="sourceTableList" value='<%= preSelectedRecord %>' onchange="handleEvent(this)">
		<br>
			<bean:define id="sourceTableList1" name="ClientTableDetailsForm" property="sourceTableList"/>
			<br>
			<html:option value="select">Select </html:option>	
			<br>
			<html:options name="sourceTableList1"/>
			<br>
		</html:select>
		<br>
		<html:hidden name="ClientTableDetailsForm" property="selectedRecord" id="selectedRecord"/>
		<br>
 
	</logic:notEmpty >
