PlayFramework validation error message customisation -

-

i have simple html form in play template field definition below:

<div class="form-group">     <h3>description</h3>     <label for="description" class="sr-only">description         @for(error <- form("description").errors) {         <p>@error.message</p> }     </label>      <textarea class="form-control" rows="4" name="description"></textarea> </div>

in corresponding model, have @required annotation on description field this:

@required(message="model.description") public string description;

in conf/messages, following defined:

model.description=please provide description

when run application , supply empty value, empty value marked error framework. however, error message see (generated html view->source in browser):

<label for="description" class="sr-only">description <p>model.description</p>  </label>

so seems message key in annotation not being resolved.what doing wrong?

thank in advance.

update: added following in controller see if conf/messages file being picked up:

system.out.println(messages.get("model.description"));

it generated following output in console:

please provide description

so, messages file being picked up. form still display lookup key.

have tried changing line:

<p>@error.message</p>

to:

<p>@messages.get(error.message)</p>
