Hello,I was missing a t:messages component as I want to show 'entry was deleted' 'entry was saved ...' messages directly or after a redirect.
I wrote my own one but it is not very beautiful. It uses a application state object stored into the session 'MessageStore'. I inject the message store into my page class, add messages and the component reads the messages. The reading of the messages deletes them from the store.
Currently, I need to inject two objects into a page class
@SessionState(create = true)
private MessagesStore messagesStore;
@Inject
private Messages messages;
public Object onSuccess(){
messagesStore.textMessage(messages.get("foo"));
return null;
}
I would like to inject only one object and use it like
messageStore.message("foo");
in order to get the "foo" message from the resources.
Do you have any ideas how to achieve this?
Best Regards
Sebastian Hennebrueder
Below you can find the component class.
The component class
public class Messages {
@SessionState
private MessagesStore messagesStore;
private List<String> messages;
@Property
private String message;
@BeginRender
boolean beginRender(){
if(messagesStore.empty())
return false;
messages = messagesStore.getMessages();
return true;
}
public List<String> getMessages() {
return messages;
}
}
Component template
<body xmlns="http://www.w3.org/1999/xhtml";
xmlns:t="http://tapestry.apache.org/schema/tapestry_5_1_0.xsd";>
<ul class="messages">
<t:loop source="messages" value="message">
<li>${message}</li>
</t:loop>
</ul>
</body>
