Im still having problems getting this. I just started using struts so
please bear with me here. But can someone please email me something similar
to the logic-iterate example that cmoes with the example-taglibs demo ? I
am getting null pointer errors and I dont if it is my struts distribution or
my own inability to grock this....
i will try not to toxify this list with any more of this .... its just that
if I cant model a formbean w/a grid of data struts is worthless to me,
because my whole world is executing functions w/import tables.

Paul,
a concrete example using modified tag:
jsp:
<logic:iterate id="parameter" name="ParametersForm"
property="parameterList">
.................
<html:text name="parameter" property="value" indexed="true"
onchange="validate(this)"/>
.................
</logic:iterate>
in my form bean (using a vector):
public final class ParametersForm extends ActionForm
{
/**
* The parameter list
*/
private Vector parameterList = new Vector();
/**
* Return the list of parameters
*/
public Vector getParameterList()
{
return(this.parameterList);
}
/**
* Set the list of parameters
*
* @param parameterList The new list
*/
public void setParameterList(Vector parameterList)
{
this.parameterList = parameterList;
}
/**
* Get a particular parameter from the parameterList, based on index
*
* @param index The index of the parameter to retrieve
*/
public Parameter getParameter(int index)
{
return (Parameter)parameterList.elementAt(index);
}
}
Hope that helps,
Dave

sorry i send the email accidently :
doesnt :
...
<INPUT type="text" name="qty" value="1">
<INPUT type="text" name="qty" value="2">
<INPUT type="text" name="qty" value="3">
...
In your class:
String[] qtys = request.getParameterValues("qty");
defeat the purpose of having a form bean which seems like a kind of servlet
abstraction of an html form ? i dont really care. I would just like to see
some sample code that works. I have searched through the quagmire that is
the mail archives and every thread ends w/confusing comments.
