null reference exception

[Yustie]

Hi,

I'm getting this error message at run time:

Unhandled exception at line 6, column 2 in http://localhost:53860/Scripts/TwitterBootstrapMvcJs--3.0.1.js

0x800a138f - JavaScript runtime error: Unable to get property 'setDefaults' of undefined or null reference.

I'm including this file as the last one of all js scripts. What am I doing wrong?

[DmitryEfimenko]

I think you might have a javascript file jquery.validate.js missing.

[Yustie]

You where right, didn't know I needed that one. It's included. But now it gives me this error:

Unhandled exception at line 23, column 4 in http://localhost:53860/Scripts/TwitterBootstrapMvcJs--3.0.1.js

0x800a01b6 - JavaScript runtime error: Object doesn't support property or method 'typeahead'

Am I missing another script?

[DmitryEfimenko]

I suppose you are missing bootstrap.typeahead.js. Check out docs for typeahead. It's there.

[Yustie]

I have that file referenced. Seemed that I had to clear my cache as well.

But I still don't get it to work. I'm typing but nothing happens. This is what I got:

@Html.Bootstrap().TextBoxFor(x => x.State).TypeAhead(new TypeAhead().Controller("Home").Action("GetCountries"))

I have a breakpoint set in the home controller and I see it's getting there with results. But they are not showed in that textbox control.

[DmitryEfimenko]

please show me html rendered by BMVC code.

[Yustie]

This is it:

<input autocomplete="off" class="form-control" data-minLength="1" data-provide="typeahead" data-url="/Home/GetCountries" id="Country" name="Country" type="text" value="" />

[DmitryEfimenko]

I'm not sure what's wrong. What version of JQuery is referenced?

[Yustie]

<script src="http://code.jquery.com/jquery-2.0.3.min.js"></script> <script src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.11.0/jquery.validate.js"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.9.2/jquery-ui.min.js"></script> <script src="@Url.Content("~/Scripts/bootstrap.typeahead.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/TwitterBootstrapMvcJs-3.0.1.js")" type="text/javascript"></script>

[DmitryEfimenko]

everything looks right. Please contact me via email.

[Yustie]

I fixed it, the problem was, I was passing a complete Entity Framework object. Instead of just the country name. I did result.Select(x => x.name) in the return new JsonResult() block.

[DmitryEfimenko]

All right, closing the issue.
