event.getRenderable()

[Hans Nieuwenhuis]

is there a sample available for the use of

event.getRenderable()

[Joas]

I don't think there is sample code attached yet, but to give a small example:

Code: Select all

function onRender(event) {
   var _element = event.getRenderable();
   
   if (_element.getName() == "btn_edit") {
      var _record = event.getRecord();
      _element.enabled = (_record.is_active);
   }
}

The result is that the "btn_edit" is only enabled for active records.

Did you test this code in the latest version (6.0.0 b3 - build 1210) ?

When I use the method :

Code: Select all

function onRender1(event) {
   
      var _element = event.getRenderable();
      
      if (_element.getName() == "pers_achternaam") {
         /** @type JSRecord<db:/udm/test1> */         
         var _record = event.getRecord();
         if (_record.pers_achternaam == 'M.' ){
               _element.enabled = false;
         }
         else {
               _element.enabled = true;
         }
           
      }
}

I get the following error for each record in the form :
(Line 27 is var _element = event.getRenderable();)

Code: Select all

You're right, unfortunately there is an issue with getRenderable in b3.
R&D is already aware of this and working on fixing it.
