loadRecord binding causing "out of stack space"/"too much recursion"

[c54283]

Hello, Help, Anyone?

On an application that is used across several timezones and with different regional settings, some users are reporting an issue I was unable to replicate.
With extra logging, the origin was detected to be in calling of https://docs.sencha.com/extjs/7.1.0/...hod-loadRecord. Any ideas of what it could be and how to troubleshoot the issue?

I cannot share code, but the view structure being loaded is the following:

items: [
  {
   xtype: 'form',
   itemId: 'MailContentForm',
   ...,
   items: [
    {
     xtype: 'container',
     ...,
     items: [
      {
       xtype: 'container',
       ...
       items: [
        {
         xtype: 'container',
         layout: 'hbox',
         items: [
          {
           xtype: 'textfield',
           ...
          },
          {
           xtype: 'checkboxfield',
           ...
          }
         ]
        },
        ...
       ]
      },
      {
       xtype: 'container',
       ...
       items: [
        {
         xtype: 'fieldset',
         ...,
         items: [
          {
           xtype: 'textfield',
           ...,
           listeners: {
            change: {
             ...
            }
           }
          },
          ...
         ]
        }
       ]
      }
     ]
    },
    {
     xtype: 'textfield',
     ...
    },
    {
     xtype: 'textareafield',
     ...
    }
   ]
  }
 ]
}

Notice that it works on most users so i kind of having hard time replicating the issue so i can try troubleshooting it.


Thanks in advance,
João

Finally replicate the issue, debugging loadRecord, happens on setValue of object of type "Ext.form.field.Text" of type date on timezone Indiana (-5) but not on timezone UTC (0).

Finally on to something, seem like it is a fireEvent change recursion. The fireEvent compares the old value and the new, if they are the same it suppress the event.... so the folowing code:

onTextfieldChange: function(field, newValue, oldValue, eOpts)
{
if(newValue !== "")
{
field.setValue(Ext.Date.format( new Date(newValue), '${Date.Long.Format}'));
}
}

will causes a recursion of change event that generates a new change event in TextField, only when Ext.Date.format( new Date(newValue), '${Date.Long.Format}') is diferent from newValue.

****ing crazy...

guess what...

Some obscure thing, the date goes back one day and keeps fireing the event...

Ext.Date.format(new Date('2013-02-06'), 'Y-m-d') in timezone UTC-5 Indiana results in '2013-02-05'

Now thats a BUG!
