Re: Dependent drop down list
Hi Simeon, Could you please provide some sample? I would like to implement dependent drop down list ( partial page rendering)? Thanks. Sri.

Re: dependent drop down list, ognl.InappropriateExpressionException
Robert,
The Option component expects that the selected parameter is bound to
an expression that it can read *and* write to. In other words it
expects the expression to evaluate to a bean property.
You expression works on a render (read) as it evals to a boolean and
that's ok, a value would be what a getter method would return.
However, on a rewind (write), Option is trying to set the property
that the expression evaluates to - and that doesn't work with the
expresson you have.
Hence the exception.
Geoff
public class InappropriateExpressionException
extends OgnlException
Exception thrown if an OGNL expression is evaluated in the wrong
context; the usual case is when an expression that does not end in a
property reference is passed to setValue.

Hi,

This is my very simple test case.

DAYS[i-1] = i;
}
}
public abstract String getMonth();

public abstract void setMonthIndex(int l);

public abstract void setDay(int i);
public abstract int getDayIndex();
public abstract void setDayIndex(int l);
public abstract Calendar getDate();
public abstract void setDate(Calendar date);
public Iterator getMonthValues() {
String months[] = new
DateFormatSymbols(getPage().getLocale()).getMonths();
if (months[months.length - 1].length() > 1) {
return new ArrayIterator(months);
}
return new ArrayIterator(months, 0, months.length-1);
}
public Iterator getDayValues() {
return new ArrayIterator(DAYS, 0,
getDate().getActualMaximum(Calendar.DAY_OF_MONTH));
}
@Override
public void finishLoad(IRequestCycle arg0, IPageLoader arg1,
IComponentSpecification arg2) {
super.finishLoad(arg0, arg1, arg2);
Calendar c = Calendar.getInstance(getPage().getLocale());
c.setTime(new Date());
setDate(c);
}
}
The first time the page renders without errors. The correct values are
preselected.
But when i select a new month i get an exception:
org.apache.hivemind.ApplicationRuntimeException
Unable to update OGNL expression '' of [EMAIL
PROTECTED] to false: Inappropriate OGNL expression:
date.get(@[EMAIL PROTECTED]) == day
ognl.InappropriateExpressionException
Inappropriate OGNL expression: date.get(@[EMAIL PROTECTED]) == day
What's going wrong? I'm running out of ideas.

Re: Dependent drop down list
I've implemented Sam's solution in my project (thanks Sam !). When the page is refreshed with the new items in the drop down list, i would like that this form element keep the focus but the focus is reset to the first element in the form ... Any advice is welcome. Stephane Sam Gendler wrote: I do this frequently, but I reload the entire page so that it doesn't get out of sync with rewind. Declare your form like this: Then, within the html element that will become the drop down, include the following: onchange="javascript:this.form.events.refresh();" This will cause the form to call your refresh listener (which bypasses validation), so you can change values before the form is rendered back to the client. Then a submit button will call the submit listener, which will perform validation and let you treat the form as though it was submitted. --sam On 5/5/06, Stephane Decleire <[EMAIL PROTECTED]> wrote: But what about the errors that would come up during the rewind of the form data ?

Hi Simeon, That would be very helpfull thanks. If you could do that please let me know how to get to it. Sorry but I haven't heard of tassel.
