DynaActionForm and radio-buttons
Hi,
i have a problem with handling my DynaActionsForm (Struts 1.1)and
radio-buttons.
In the JSP is a iteration over a bean (bookingPaymentTickets) that creates
radio-options.
<logic:iterate id="tickets" name="bookingPaymentTickets" scope="request">
Price 1<html:radio property="price" value="1" styleClass="radiobutton"
indexed="true" />
Price 2<html:radio property="price" value="2" styleClass="radiobutton"
indexed="true" />
Price 3<html:radio property="price" value="3" styleClass="radiobutton"
indexed="true" />
<br>
</logic:iterate>
so, for every iteration there are 3 radio-fields.
In my struts-config.xml the form is declared as following:
<form-bean name="bookingPaymentEditForm"
type="org.apache.struts.validator.DynaValidatorForm" dynamic="true">
<form-property name="price" type="java.lang.String[]" initial="1" />
</form-bean>
When I look at the HTTP-Monitor after sending the form, i see:
org.apache.struts.taglib.html.BEAN[1].price 1
org.apache.struts.taglib.html.BEAN[0].price 2
No, i want to read the values of the checkboxes in my action:
DynaActionForm form = (DynaActionForm)actionForm;
String price1 = (String) form.get("price",0);
String price2 = (String) form.get("price",1);
...
But that doesn't work :-(
I get the following StackTrace:
java.lang.ArrayIndexOutOfBoundsException
at java.lang.reflect.Array.get(Native Method)
at
org.apache.struts.action.DynaActionForm.get(DynaActionForm.java:296)
at
ticketmaker.actions.booking.bookingPaymentEditAction.execute(bookingPaymentE
ditAction.java:40)
at
org.apache.struts.action.RequestProcessor.processActionPerform(RequestProces
sor.java:484)
....
Anybody know where the problem is?
Does anybody know a better way to solve the problem of having mutliple lines
of radio-buttons?
Thnx

Hello Daniel,
let me ask, for the reason of using radio:
you are setting it with: price1 OR price2 OR price3
isn´t it?
so, you get an Array of size 1. (you can click only one)
thats reason for ArrayIndexOutOfBoundsException
perhaps, when you will set multiple values for your price-property
you can do something like this:
<html:select property="price" multiple="true">
<html:option value="1">Price1</html:option>
<html:option value="2">Price2</html:option>
<html:option value="3">Price3</html:option>
</html:select>
then you got an got an array e.g size:2, if
you click 2 items in a browser.
on clicking Pric1 AND Price3
form.get("price",1); gets the value for Price3
i hope i understand you...
greetings
