Conditional translator

[Nathan Quirynen <na...@pensionarchitects.be>]

Hi,

In multiple forms I have a textfield containing a bank account number 
and next to it a select component containing the account number type (enum).
Now I want to add a translator for the textfield, to automaticaly format 
the value, but the formatting is different for each account number type. 
I now have a translator for each type, but it would be nice if i could 
make just 1 and somehow pass the type. Is there a way to do this?

You can dynamically create translator:

@Inject
private FieldTranslatorSource fieldTranslatorSource;

public getMyTranslator() {
  switch(myAccountType) {
    case ACCOUNT_TYPE1:
      return createTranslator("myField", "myTranslator1");
    // other types
  }
  return null;
}

protected FieldTranslator createTranslator(final String componentId, final
String translator) {
  final ComponentResources componentResources =
resources.getEmbeddedComponent(componentId).getComponentResources();
  return fieldTranslatorSource.createTranslator(componentResources,
translator);
}

In this example account type should be populated before account number. So
if select is placed after textfield it will result with incorect behaviour.
To fix this I usually use trick with FormFragment component:

<t:formfragment visible="true">
  <t:textfield .../>
</t:formfragment/>

<t:select .../>
