Cutom Error Messages - Subtituting values

Question

Hi All,
Im new to JSF, and finding problems substituting values, when customizing the error messages.
My input text item is defined as
<h:outputText value="My Number:"/>
<h:inputText id="ucasNumber" value="#{start.myNumber}"
required="true"
validator="#{start.validatemyNumber}">
<f:validateLength maximum="9" minimum="9"/>
<f:attribute name="fieldRef" value="My Number" />
<f:attribute name="custMsg" value="Please enter My number " />
</h:inputText>
I have redefined the standard error for the minimum length within the .properties file as
javax.faces.validator.LengthValidator.MINIMUM_detail=VALUE_MIN_LENGTH
VALUE_MIN_LENGTH_MSG_detail = Minimum length for ''{0}'' is ''{1}''.
And this is from the Phase listner...
UIComponent c = root.findComponent(clientId);
String fieldRef = (String) c.getAttributes().get("fieldRef");
if (fieldRef != null) {
Iterator j = fc.getMessages(clientId);
while (j.hasNext()) {
else if ("VALUE_MIN_LENGTH".equalsIgnoreCase(detail)) {
String custMsgPattern = rb.getString("VALUE_MIN_LENGTH_MSG_detail");
Object[] params = new Object[2];
params[0] = fieldRef;
// params[1] = "7";
String custMsg =MessageFormat.format(custMsgPattern, params);
fm.setSummary(custMsg);
fm.setDetail(custMsg);
When I hard code a value (ie param[1]="7") it is fine...and the vvalue is substituted correctly and I obtain the correct message.
What I like to know, is how I would obtain the minimum value from the item that causes the error - in this case '9'.
Thank in advance
AB

That looks really similar to this tutorial:

Try walking through it and see if you can catch your problem. Then again, maybe you already have and that's where you got the idea originally. If that's the case, I probably can't help you beyond that as I went a different root when customizing my error messages.
I also just posted this in another thread. Probably more useful to Bret, but you may want to look at it anyways.
