Invalid Field Value when using Map
Hi,
I have a form that uses maps to store data as shown below. When the user enters valid numbers it works as expected, but when user enters non digit characters in the text field a String object is saved
in the map rather than showing a "Invalid field value for field <field name>" message which is done for basic data types like int/long/double. Is this something that struts has not implemented for
maps yet, as the annotations provide the expected data type?
@Element(value=java.lang.Double.class)
private HashMap<Long, Double> deferralAmountValue = new HashMap<Long,Double>();
@Element(value=java.lang.Double.class)
private HashMap<Long, Double> deferralPercentValue = new HashMap<Long,Double>();
Thanks,
Prasanth

I also like to not see that value in Map but maybe it's required for
some reason - I didn't check. But you may use following workaround:
if (!hasFieldErrors() || !getFieldErrors().contains(myFieldName) {
// my extra customized validation logic for myFieldName
}

Me too! Could you please put a break-point at your app's [1] and see
what happens next for that field?

Re: Invalid Field Value when using Map
Posted by Prasanth Pasala <pp...@pangburngroup.com>.
I have built a test project to just test the Map variables. In the validate method it does give a String object (for value of map). But seems like a field error is also added. If I try to use the map
in validate method I would get a class cast exception, but if I don't do anything with the map values then the input page is displayed with invalid field value error.
So I guess the issue is that my validate method is trying to validate the values in the map and that causes the exception, as the map has String values in it.
I have to update the validation methods to check if the value is of type Double or not. Is this how it is supposed to work? I would have thought that a field error would be added and the String value
would not be added to the Map as the code is expecting Doubles.
Thanks,
Prasanth

Hi,
I think putting breakpoints at [1] and [2] and seeing if you reach there and what happens next can help proceeding this issue.

Re: Invalid Field Value when using Map
Posted by Prasanth <db...@pangburngroup.com>.
Hi Yasser,
The conversion error occurs when the field is not a map. I have a form with int/long fields, if the user enters non numeric value the form display error.
The actions are validation aware and the control does come to validation method. It is in the validation method that I usually get exceptions as the code is expecting to have a Double but the type of
the object in the map is a String. I have tried to check in the validate method if the object is of type Double and if it is not a Double add a field error. When I do that OGNL seems to have an issue
when displaying the input form with the values in the map. Seems like OGNL is now expecting a Double value and is not able to handle a String object being present in the map. The JSP stops at the
field which has String value.
So even if I add additional validations to make sure all values in the map are Doubles it would still cause a problem as Struts would not be able to display the input form.
Thanks,
Prasanth

Oh interesting!
Have you seen [1]? e.g. conversion error interceptor should be present
in your interceptor stack. To debug, for example put a number field
which is not a map and see if conversion error appears - I think you
should also have fieldErrors tag in your jsp.
It seems your action also should be ValidationAware. Put a break-point
at [2] and see if your code reaches there and what happens next.

Hi Yasser,
I think at run time you can add any type of objects you want to the map. The checks are only at compile time on the data types of objects added to Maps.

Hi Prasanth,
I'm surprised how you get non digit characters in your map while both key and value are not String!
