[6.5.2/3 Classic] Bug on combobox

[wki01]

Good morning.
There's a bug on the combobox field that creates really strange situations
It is present on version 6.5.2, 6.5.3, 6.5.4.63 and on 6.6.0.115.


See attached picture.
= instead of ==


Here on 6.5.3

That's just assigning to value and testing the thruthiness of it.

What actual "bug" are you observing in the operation?

Unfortunately I could not recreate it on a fiddle.
The procedure is too complex.


However there are several combos connected in cascade mode and clicking on some "select" events are launched without any need.


The thing is random but magically everything works if I change = with ==


We are sure that it is wanted and that it is not a bug?
Very strange the way this piece of code is written

            // HACK: form.isDirty() always returns true, but it should not be dirty right after the values are set via the binding
            vm.notify()   
            form.getForm().getFields().each(function(field) {
                field.resetOriginalValue();    
                if (field.xtype == "combo") {
                                       var rec = field.findRecordByDisplay(field.getValue())
                                       field.lastSelectedRecords = rec
                                       field.lastSelectedRecords[0] = rec
                }
            });

I had to add the lines in red to make my code work.
I do not understand if the code I wrote is not good or if there is a very thin bug in the function resetOriginalValue()
