Autocomplete Has Null Exception When Clearing Field If Bound With bind-Value

[Robert]

In the below code I get a null reference exception when emptying the autocomplete, either by clearing it or clicking the X.

If I remove the bind-Value parameter, I do not get the exception.

Am I doing something wrong?

<div class="col-md-3">

<EjsAutoComplete @bind-Value="_boundValue" TValue="string" Placeholder="Add a country" FloatLabelType="@FloatLabelType.Always" Query="@QueryCountries" MinLength="2">

<EjsDataManager AdaptorInstance="@typeof(DataAdaptorForCountriesBasic)" Adaptor="Adaptors.CustomAdaptor"></EjsDataManager>

<AutoCompleteFieldSettings Value="CountryGuid" Text="CountryName"></AutoCompleteFieldSettings>

</EjsAutoComplete>

</div>

...

@code{

private string _boundValue;

Exception from Chrome console:
