c# - Kendo UI TreeListDataSource Read() only works when running locally -

-

i have kendo treelist datasource defined as

    var ds = new kendo.data.treelistdatasource({                     transport: {                         read: {                             url: "/home/read/",                             type: "post",                             datatype: "json"                         }},                      schema:...                      }

my controller's read method is:

[httppost] public string read() {     log.info("start read()");     var vm = vmhelper.getclientorglistviewmodel();     var json = new javascriptserializer().serialize(vm.facilitylist);     log.debugformat("json read returned: {0}", json);     return json;  }

everything works great long run locally through vs once deploy our staging server, read() transport code never gets executed. 500 error. pressing f-12 view requests in ie shows 500 error

enter image description here

any ideas or suggestions on why works locally not on server , how resolve issue?

try building url using @url.action("read", "home")

var ds = new kendo.data.treelistdatasource({                 transport: {                     read: {                         url: '@url.action("read", "home")',                         type: "post",                         datatype: "json"                     }},                     schema:...                 }

if javascript code in javascript file won't able use razor helpers. in case add list of url's keep in layout file. this:

<script type="text/javascript">     var configuration;     (function (configuration) {         var urls = {             read: '@url.action("read", "home")'         }         configuration.url = urls;     })(configuration || (configuration = {})); </script>

then use as:

transport: {     read: {         url: configuration.url.read     } }

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
