output text depending on message
Hi all,
I have to output some text in the case that there isn't a message for a
component.
How can I achieve this?
<t:inputText id="aField">...
<t:message for ="aField" showDetail ...>
<t:outputText value="ok" rendered=??? aField ???
I remember that this has been discussed here but I can't find it
anymore.
Michael

Turned out to be harder than I expected to find it :-)

I vaguely recall someone submitting a new component for IfMessage
-type stuff. Search the jira issue tracker for New Component.

Thanks Volker for your help
I can't use the approach with the isXXXError() method,
because my BackingBean contains a dynamic Map with attributes.
Therefore I can't hardcode getters for the attributes or the errors.
So I try to implement such a MessagesWrapper by myself.
I create a new RequestScoped BackingBean that extends HashMap and
overwrites the getter, right?
public Object get(Object key) {
String keyString = (String) key;
return
FacesContext.getCurrentInstance().getMessages(keyString).hasNext();
}
Thanks for putting me on this way.

no, there isn't, but if you realy want you can implement such a map
yourselve.
Or, as Gerald wrote, put a method like this in your backingBean
public void isCarIdError() {
return FacesContext.getCurrentInstance().getMessages("carId").hasNext();
}
that should do.

Thanks, but this would not work in my case.
I have to check whether there are messages for specific fields.
Better sample:
I have a required editable inputField carID and want to output the name of the car if there are no errors for the carID field. If the carID field is changed then I clear the carName immediately via JS. When there is now a validation error for carID, then the old carName is displayed again.
I want to suppress the carName in errorCase.
<t:inputText id="carId" required="true"
value="#{MyBean.attributes['carId']}"
onchange="document.getElementById('carname').innerText='')";/>
<t:message for="carId" showDetail...>
<t:outputText id="carName"
value="#{MyBean.attributes['carName']}"
rendered=???empty messages['carId']???
I hope there is a Map with messages, that would be accessible with the fieldID????

Hi,
what is about rendering the outputText in case if there are no
messages in the FacesContext waiting to be displayed:
FacesContext.getCurrentInstance().getMessages().hasNext()
Place this in a method-binding in the backend. Should work to me.
cheers,
Gerald
