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

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

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:
