Problem Validating html:file

[Vijay RamaRaju]

Hi.,
I have a problem while trying to validate <html:file> control. When the user types in the invalid textual information in the browse button., when i submit the form it is giving the javascript error saying the file control is null or not an object. Any Solution.

Here is some code where I perform some validation in my execute method. I am not sure how to do client side java script validation or if this validation could be performed by the validation framework. I don't see a reason why this could not be done in the form's validate method (and now I am wondering why I am not doing that).

        // check if the file is valid, the size will be zero for invalid files
        FormFile importFile = importForm.getImportFile();
        int size = importFile.getFileSize();
        if (size == 0)
        {
            String errmsg = "'" + importFile.getFileName() + "' does not exist or is invalid.";
            ActionError error = new ActionError("App.Error.General", errmsg);
            errors.add(ActionErrors.GLOBAL_ERROR, error);
        }

If somebody else has a better way of validating this, please pass it along.
