ember.js - Manual Ember computed property not working while helper properties do -


I have the following controllers with many mathematical properties, most of whom use auxiliary functions all referred to in the template Work flawlessly However, the two values ​​computed manually fail, if I add them to my template because those properties which are undefined when the reference is first run. I get the Unkot Type error: property 'length' can not be read from numeral.js 'undefined' because if this is the wrong way with the way I created it? Are the calculations properties built with helpers working properly while referencing the exact same model data? 

  AdvisorAdvanced Controller = Ember.ArrayController.extend Open: Ember.computed.filterBy "Model", "Status", "Open" Pending: Ember.computed.filterBy "Model", "Status" , "Pending" OpenWells: Amber computed.mapbay "Open", "value" pending value: amber dot coop.map "pending", "value" opencount: ember.computed.alias "open.length" pending question: Ember.computed .alias "pending.length" openTotal: Ember.computed.sum "openValues" Pending: Ember.computed.sum "pendingValues" showPending: Ember.computed.gt format "$ 0,0.00"). Property "OpenTotal" pending totals: (- (& gt; Number (@ "pending pending"). Format "$ 0", "Pending Coat", 0 OpenLySD: (-> Number, "0.00"). Property " Pending "  
 I guess this model still removes when it is removed. This property is not a problem for properties because the resulting value is another Things are not being trusted, and they can solve at their own time.   
  
  opencount: function () {open back and open.length;}. Property ('open.length')  < / Pre> 
 In this way you will try to reach  length  to  open , only when  open  is defined and "true" ".

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number".

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
