How to Use Internalization i18n in a Controller in SAPUI5?

问题

Could anyone please explain how it's possible to use a i18n text in a setValueStateText method in a controller?

oTP.setValueStateText("{i18n>co_Maximal_60_h}");

The error msg in the dialog shows only "{i18n>co_Maximal_60_h}" and not the real text.

You cannot set the binding string via setter method. Here you have 2 options:

1. set the binding right in the view (use the same string but in XML)

2. utilize the ResourceBundle:

   var oResourceBundle = this.getOwnerComponent().getModel("i18n").getResourceBundle();
   
   var sTxt = oResourceBundle.getText("co_Maximal_60_h");
   
   oTP.setValueStateText(sTxt);
   

I'd recommend to add a reusable method to your BaseController with a name "i18n", so whenever you need it, call 'this.i18n("i18n_key")'.

the resource bundle is in the following way accessible in a controller:

...
  var oResourceBundle = this.getView().getModel("i18n").getResourceBundle();
  oTP.setValueStateText(oResourceBundle.getText("co_Maximal_60_h"));
...
