Hi all,

I have a weird behaviour of takeValuesFromRequest. I have a page with
a form that has a radio button group having values from 1 to n.

<woform>
   <worepetition>
     <radiobutton>
   </worepetition>
</woform>

with

radiobutton : WORadioButton {
   name = "reportSelect";
   value = counter;
   selection = selectedReport;
}

gives

<form name="form_0_0_3_25_5" method="post" action=""
             <input type="radio" value="1" name="reportSelect">
             <input type="radio" value="2" name="reportSelect">
             <input type="radio" value="3" name="reportSelect">
             ...
       <input type="submit" name="0.0.3.25.5.7.0">
   </form>

selectedReport is an int variable that is set to 0 in
appendToResponse. When I select one of the radiobuttons and submit
the form I get the appropriate value in selectedReport for all radio
buttons except for the first one. That is if I select the first one
the value of selectedReport in my form action is 0 and not 1 as I
would expect.
I added takeValuesFromRequest to my component and by checking the
form values in WORequest I can see that the value 1 is there but I
don't know why just that value is not assigned to the variable. The
only way I found to make this work is to add

if (aRequest.formValueForKey("reportSelect") != null) {
        selectedReport = new Integer((String)aRequest.formValueForKey
("reportSelect")).intValue();
}

to takeValuesFromRequest to manually assign the value. But it should
not be necessary to do so! So does anyone have an idea what is going
wrong or did someone else observe that behaviour?

I could make a mistack but I think radio button take only String value, try use selectedReport as String

changed it to String and when I select the first radio button no value gets into the variable as before and by selecting one of the other buttons I get:

<com.webobjects.appserver._private.WOComponentRequestHandler>: Exception occurred while handling request:
java.lang.IllegalArgumentException: While trying to set the field "selectedReport" on an object of type com.oyosys.source.administration.AdminNewVersion we expected a java.lang.String but received a java.lang.Integer with a value of 2. This often happens if you forget to use a formatter.

So I could use a formatter to prevent this error but this doesn't change the fact that for selecting button No. 1 no assignement seems to be made in takeValuesFromRequest for whatever reason. :-(

Ok try to use WORadioButtonList, instead of WORepetition, and use a list of Strings: new String[]{"1", "2", "3", ..}

<wo:WOForm>
<wo:WORadioButtonList list="$myListOfStrings" selection="$ selectedReport" />
<wo:WOSubmitButton action="" />
</wo:WOForm>
