DialogModes.NO in script ignored when called from action via Bridge Batch

[fernold]

I have a fully working action which includes a script call. The script includes an executeAction with suppressed dialogs (DialogModes.NO).

Everything works flawlessly when run in photoshop and also when using Automate->Batch... in Photoshop.

However, when I select the images in Bridge and then invoke the action via Tools-Photoshop->Batch, The dialog keeps appearing abd interrupts the action. DialogModes.NO seems to be ignored when running it this way.

Thankful for any insight into this.

Script:

main(); 
  function main(){ 
    if(!documents.length) return; 
    makeLayerActiveByName("Layer  0"); 
    var fileName = decodeURI(activeDocument.name);
    var fileName = fileName.substring(0,fileName.length - 4)
    activeDocument.activeLayer.name= decodeURI(fileName); 
  }

function makeLayerActiveByName(nm) { 
  function cTID(s) { return app.charIDToTypeID(s); }; 
 
    try { 
      var desc5 = new ActionDescriptor(); 
      var ref4 = new ActionReference(); 
      ref4.putName( cTID('Lyr '),  nm); 
      desc5.putReference( cTID('null'), ref4 ); 
      desc5.putBoolean( cTID('MkVs'), false ); 
      executeAction( cTID('slct'), desc5, DialogModes.NO ); 
    return true; 
 
    } catch (e) { 
      return false; 
    }  
  };
