I do this validation manually and add a message to that control if the value
already exists.
I am not using Hibernate Validator at all. In every action that requires
validation, I do this. This handles all complex cases that I have come across.
Does anyone know if it is possible to bind a method of a seam component
directly to the view for validation?
Something like the following
<h:inputText id="#{myId}" value="#{myValue}"
converter="#{myValue.validateMyValue}"/>
Currently I am using
public static int addMessages(Map<String, String> m)
| {
| for(String key : m.keySet())
| {
| if(key.startsWith("globalMessage"))
| {
| FacesMessages.instance().add(m.get(key));
| }
| else
| {
| FacesMessages.instance().addToControl(key, m.get(key));
| }
| }
| return m.size();
| }
And use this as follows
private boolean isValid()
| {
| HashMap<String, String> errorMessages = new HashMap<String, String>();
|
|
| ValidatonUtil.checkNull("condition",
| poPipe.getCondition(),
| "Condition required!",
| errorMessages);
|
| ValidatonUtil.checkUniquePONuml("poNum",
| poPipe.getPoNum(),
| "You PO # must be
unique!",
| errorMessages);
|
| ValidatonUtil.checkPositiveDouble("amountOrdered",
| poPipe.getAmountOrdered(),
| "Postive amount required!",
| errorMessages);
|
| ValidatonUtil.checkDateRealistic("date",
| poPipe.getDate(),
| "Date required!",
| errorMessages);
|
| ValidatonUtil.checkDateRealistic("dateAvailable",
| poPipe.getDatePromised(),
| "Date Available required!",
| errorMessages);
|
| return (ValidatonUtil.addMessages(errorMessages)==0) ? true : false;
| }
I call a method like this every time I need to validate. These messages are
added after jsf validations. If for example "0www8" is entered into a numeric
field JSF messages appear and mine do not. I would like for all of these
validations to occur at the same time. I would also like to not have to know
the id of the component I want to attach the messages. If I could specify the
method to use to validate and put it on the input field, I would like this to
be tied together automatically.
Is this possible and could someone point me to an example?
