Hi,
I've found that ComboBoxItem which is bounded to DataSource is behaving somehow incorrectly.
The problem is that ComboBox now is triggering fetchData with criteria := {displayFieldName: getValue()} instead and our datasource can't find any records with "name"=2
Firstly I cannot find out why ComboBox triggers that fetch at all because I've picked up item from drop down.
Bug is here:
Please fix this then you'll have time.
PS.
I've analyzed why ComboBox triggers that fetch at all and found that `this.shouldFetchMissingDisplayValue(elementValue)`
is returning true.
FormItem._shouldFetchMissingValue(..): in this._displayFieldCache object I see only one record instead of full picklist record set.
Shouldn't be this method related with `mapDisplayToValue()` method? because input value mapping to ID is done by this method not by some _displayFieldCache object? if _displayFieldCache is cleared `mapDisplayToValue()` works correctly but that _shouldFetchMissingValue() returns false - not logical.
Thanks.

I've found that ComboBoxItem which is bounded to DataSource is behaving somehow incorrectly.
Code:
Theory:
valueMap - a dictionary how to map input string to ID (with data bound it's implemented differently, but logical the same)
getValue() - real value of ComboBoxItem will return ID if found in valueMap or the same value as getEnteredValue()
getEnteredValue() - value of ComboBoxItem which is entered or selected by user (string)
displayFieldName - is field name which will be searched by if input is not found in picklist
valueFieldName - is field name which stores real value for ComboBoxItem (basically it`s primary key of datasource)
If ComboBox will find `getEnteredValue()` in it's `valueMap` then resolved ID will be used,
but if not found then ComboBox will trigger fetchData on DataSource with criteria := {displayFieldName: getEnteredValue()}.Firstly I cannot find out why ComboBox triggers that fetch at all because I've picked up item from drop down.
Bug is here:
Code:
//ComboBoxItem.js at handleEditorExit method:
// Otherwise, consider the value to be a display value. If we have an ODS and
// display field, check whether we have a data value for it. If not, try to fetch
// a data value for this display value using _checkForValueFieldValue().
} else if (ods != null && displayField != null
&& elementValue != null && elementValue != "" &&
this.shouldFetchMissingDisplayValue(elementValue)
)
{
this._checkForValueFieldValue(value); // <- Here must be an elementValue not a value.
