c# - Multiple TempData variables passed to same action -

-

i'm creating asp.net web application using mvc , entity framework. have 2 different success messages passing index action when user clocks in or clocks out. success message print correctly when user clocks in, not when user clocks out reason.

the actions similar , used of same conventions can't figure out why 1 print , not. i've tried debugging , there no red flags , updates in database should. not possible pass multiple tempdata variables same action?

here relevant code:

controller

        // get: timeclocks     public actionresult index()     {         viewbag.clockinsuccess = tempdata["clockinsuccess"];         viewbag.clockoutsuccess = tempdata["clockoutsuccess"];         return view();     }     [httppost]     public actionresult clockin(timeclock timeclock)     {         if(db.timeclocks.tolist().count == 1)         {             modelstate.addmodelerror("existserror", "you clocked in at" + timeclock.clockin);         }         string currentuserid = user.identity.getuserid();         applicationuser currentuser = db.users.firstordefault(x => x.id == currentuserid);         timeclock.applicationuser = currentuser;         timeclock.clockin = datetime.now;          if (modelstate.isvalid)         {             db.timeclocks.removerange(db.timeclocks.tolist());             db.timeclocks.add(timeclock);             db.savechanges();             tempdata["clockinsuccess"] = "you clocked in @ " + timeclock.clockin;             return redirecttoaction("index");         }          return redirecttoaction("index", timeclock);     }     [httppost]     public actionresult clockout(timeclock timeclock)     {         timeclock = db.timeclocks.firstordefault();         if(timeclock.clockin == null)         {             modelstate.addmodelerror("nullerror", "you must clock in before can clock out.");             return redirecttoaction("index");         }         timeclock.clockout = datetime.now;          if (modelstate.isvalid)         {             db.entry(timeclock).state = entitystate.modified;             db.savechanges();             tempdata["clockoutsuccess"] = "you clocked out @ " + timeclock.clockout;             return redirecttoaction("index");         }         return redirecttoaction("index", timeclock);     }``

view

@model finalproject.models.timeclock  @{     viewbag.title = "create"; }  <h2>employee time clock</h2>  @using (html.beginform("clockin", "timeclocks"))  {     @html.antiforgerytoken()      <div class="form-horizontal">         @html.validationsummary(true, "", new { @class = "text-danger" })         <div class="form-group">             <div class="col-md-offset-2 col-md-10">                 <input type="submit" value="clock in" class="btn btn-lg" />             </div>         </div>     </div> } @using (html.beginform("clockout", "timeclocks")) {     @html.antiforgerytoken()      <div class="form-horizontal">         @html.validationsummary(true, "", new { @class = "text-danger" })         <div class="form-group">             <div class="col-md-offset-2 col-md-10">                 <input type="submit" value="clock out" class="btn btn-lg" />             </div>         </div>     </div> } @{     if (@viewbag.clockinsuccess != "")     {         <p class="alert-success">@viewbag.clockinsuccess</p>     }     else if (@viewbag.clockoutsuccess != "")     {         <p class="alert-success">@viewbag.clockoutsuccess</p>     } }   <div>     @html.actionlink("back list", "index") </div>

tempdata lost once read need peek or keep: 

viewbag.clockinsuccess = tempdata.peek("clockinsuccess"); viewbag.clockoutsuccess = tempdata.peek("clockoutsuccess");

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

Image
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...
