This is a multi-part message in MIME format. --------------060906010904020105000601 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Hi, This is regarding the following validation method we have in ValidationUtils: /public static <T extends VdcActionParametersBase> ArrayList<String> validateInputs(List<Class<?>> validationGroupList, T parameters);/ I there any particular reason for supporting the validations only on objects of classes derived from VdcActionParametersBase? I guess this was done because this method is primarily intended to validate the action parameters passed to a BLL action, using the validation annotations on the parameter class. However I think this method can be useful for general use as well. e.g. I cannot add a "@Valid" annotation on a "list" or a "map" in a parameter class. So I need to iterate over the list/map, and validate each element inside the loop. The validation inside the loop can also utilize the above method if the restriction "extends VdcActionParametersBase" is removed. This will allow me to do the following in the canDoAction method: protected boolean canDoAction() { ... for(GlusterBrickEntity brick : getParameters().getGlusterVolume().getBricks()) { List<String> errors = ValidationUtils.validateInputs(getValidationGroups(), brick); if(errors != null) { for(String error : errors) { addCanDoActionMessage(error); } } } ... } Regards, Shireesh --------------060906010904020105000601 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit <html> <head> <meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"> </head> <body bgcolor="#FFFFFF" text="#000000"> Hi,<br> <br> This is regarding the following validation method we have in ValidationUtils:<br> <br> <i>public static <T extends VdcActionParametersBase> ArrayList<String> validateInputs(List<Class<?>> validationGroupList, T parameters);</i><br> <br> I there any particular reason for supporting the validations only on objects of classes derived from VdcActionParametersBase?
