Adding values to SfComboBox

[Collazo]

I'm having an issue with the adding a value to the SfComboBox.

Here is the scenario:

I have a list of companies. One of the fields is "Industry". I have placed the combobox on a page called AddCompany. When the page loads, I am retrieving a list of unique Industries that exist in the database and populating the combobox. The combobox value is bound to the Industry field of said company. I have set AllowCustom="true". When I begin typing in the combobox, I get a null reference exception.

Here is how I have the combobox defined:

 <div class="col-12">

     <SfComboBox Placeholder="Industry" AllowCustom="@true" TValue="string" TItem="string" FloatLabelType="FloatLabelType.Always" @bind-Value="@newLead.Industry" DataSource="Industries" SortOrder="Syncfusion.Blazor.DropDowns.SortOrder.Ascending" >

     </SfComboBox>

 </div>



And here is the code that populates it:

 private Lead newLead;

 private List<string> Industries = new List<string>();

 protected override async Task OnInitializedAsync()

 {

     newLead = new Lead();

     Industries = await wsService.GetIndustriesAsync();

 }

The page loads fine. All the expected items are in the combobox. But when I try to type in the box, I get the error. Am I miisi

The issue I am having is that when I try to type something that is NOT in the list, an exception is thrown.

For example, If I have 4 items in the combobox, English, Spanish, Italian, French. If I try to type German, It will throw an exception.
