  1. POASP.NET MVC 4 - ModelBinder bug
    text
    copied!<p>So I was playing around with my ASP.NET MVC 4 solution. Every thing worked fine kept adding things but something odd started happening.</p> <p>One of my Models properties was null, even though I had items in the Json passed to it.</p> <p>This was the javascript object/json passed it it:</p> <pre><code>var obj = { "plc": "False", "al": ["386", "710"], "pl": ["9530", "211", "783"] }; </code></pre> <p>I was using a Custom Model binder ... thought that might be the issue so I turned it off.</p> <p>Tried using the JavaScriptSerializer from .NET to see it that worked:</p> <pre><code>var reader = new StreamReader(Request.InputStream); Request.InputStream.Position = 0; var readToEnd = reader.ReadToEnd(); var javaScript = new JavaScriptSerializer(); var searchFarmOptions = javaScript.Deserialize&lt;Test&gt;(readToEnd); </code></pre> <p>Got all the properties set ... WOOT.</p> <p>So I tried a clean ASP.NET MVC 4 solution. To reproduce the bug.</p> <h3>This is from the Index.cshtml view</h3> <pre><code>@{ ViewBag.Title = "title"; } &lt;h1&gt;Title&lt;/h1&gt; Testing ... &lt;script src="/Scripts/jquery-1.8.2.min.js" type="text/javascript"&gt;&lt;/script&gt; &lt;script&gt; $(function() { var obj = { "1pllort": "False", "1plc": "true", "al": ["386", "710"], "pl": ["9530", "211", "783"] }; var options = { "contentType": "application/json; charset=UTF-8", "type": "POST", "data" : JSON.stringify(obj) }; $.ajax("/Home/TestPost", options).done(function(data) { console.log(data); }); }); &lt;/script&gt; </code></pre> <h3>This is my HomeController</h3> <pre><code>using System.Collections.Generic; using System.Web.Mvc; namespace MvcApplication3.Controllers { public class HomeController : Controller { public ActionResult Index() { return View("Index"); } [HttpPost] public ActionResult TestPost(Test model) { return Json(model); } } public class Test { public List&lt;int&gt; PL { get; set; } public List&lt;int&gt; AL { get; set; } public bool PLC { get; set; } public bool ALC { get; set; } } } </code></pre> <p>Yes, the bug is still there.</p> <p>Whenever I have a property starting with "pl" as my list name is .. the "pl" list is null.</p> <p>Also, it could be any name starting with "pl" ... like "plchecked"</p> <p>If I rename the "plc" to "cpl" its working.</p> <p>So what is going on here ... is there any naming restrictions in the model binder? What am I missing here?</p> <h2>Update 1</h2> <h3>Work</h3> <p>PL server side now have the right values, etc. not null, but the list of numbers.</p> <pre><code>var obj = { "pl": ["9530", "211", "783"], "1plc": "false", "pl-some-odd-value": "false", "al": ["386", "710"], "alc": "false" }; </code></pre> <h3>Don't work</h3> <p>PL server side now have <code>null</code> value.</p> <pre><code>var obj = { "pl": ["9530", "211", "783"], "al": ["386", "710"], "alc": "false", "pl-odd-value": "false" }; </code></pre> <h3>Work</h3> <p>PL has the 3 values som the json object string ... </p> <pre><code>var obj = { "pl": ["9530", "211", "783"], "al": ["386", "710"], "alc": "false", "odd-value-pl": "false" }; </code></pre>
