How to disable or unset an action button dynamically from the main dropdown menu on the record view ?

Simo Hamzaoui

I am trying to disable the 'download-pdf' and 'email-pdf' buttons if the field 'pdf-disabled-c' is set to true.

I tired overriding the record view with creating the file \custom\modules\Quotes\clients\base\views\record\record.js:

({ 
  extendsFrom:'RecordView',
  
  initialize:function(options){

    this._super('initialize',[options]);

    this.model.once('sync', function() {
      pdfDisabled = this.model.get('pdf_disabled_c');
      downloadPdf=this.getField('download-pdf');
      emailPdf=this.getField('email-pdf'); 

      if (downloadPdf && emailPdf && pdfDisabled){
        downloadPdf.setDisabled(true);
        emailPdf.setDisabled(true);
      }
    }, this);   
  },
})

The reason I used  this.model.once('sync', function()  is because when using on 'render' the value of 'pdf-disabled-c' is not present yet.   

This does work. BUT it produces a very weird error: 

The rows in the Quoted Line Items list get doubled. When I refresh the page it goes back to normal. This is obviously a very undesirable behaviour. When I delete \custom\modules\Quotes\clients\base\views\record\record.js this behaviour stops.

What I also tried and did not work was trying to unset  the buttons through \custom\Extension\modules\Quotes\Ext\clients\base\views\record\record.php

<?php

foreach ($viewdefs['Quotes']['base']['view']['record']['buttons'] as $i => $button) {
  if ($button['name'] == 'main_dropdown') {
    foreach ($button['buttons'] as $j => $btn) {
      if ($btn['name'] == 'download-pdf' || $btn['name'] == 'email-pdf') {
        unset($viewdefs['Quotes']['base']['view']['record']['buttons'][$i]['buttons'][$j]);
      }
    }
  }
}

This does remove the two buttons, but I could not get the value at this stage through $bean->pdf-disabled-c to do that dynamically.

Any suggestions on how to approach this would be gladly appreciated.

Many Thanks
