ember.js - Updating a property is not visible in the DOM -

-

i have following drop-downs:

{{view settingsapp.select2selectview     id="country-id"     contentbinding=currentcountries     optionvaluepath="content.code"     optionlabelpath="content.withflag"     selectionbinding=selectedcountry     prompt="select country ..."}}  ...  {{view settingsapp.select2selectview     id="city-id"     contentbinding=currentcities     selectionbinding=selectedcity     prompt="select city ..."}}

the bound properties defined in controller:

settingsapp.serviceseditcontroller = settingsapp.baseeditcontroller.extend(settingsapp.servicesmixin, {     needs            : ['servicesindex'],     selectedcountry  : null,     selectedcity     : null,     currentcountries : null,     currentcities    : null,     init : function () {         this._super();     },     setupcontroller : function (entry) {         this._super(entry);         var locator = settingsapp.locators.getlocator(this.get('content.properties.locator'));         var countrycode = locator.get('country'), city = locator.get('city');         this.set('currentcountries', settingsapp.countries.getcountries());         this.set('currentcities',    settingsapp.locators.getcities(countrycode));         this.set('selectedcountry',  settingsapp.countries.getcountry(countrycode));         this.set('selectedcity',     city);         // add observers now, once setup         this.addobserver('selectedcountry', this.selectedcountrychanged);     },     selectedcountrychanged: function () {         var countrycode = this.get('selectedcountry.code');         var currentcities = settingsapp.locators.getcities(countrycode);         var selectedcity = currentcities[0];         this.set('currentcities', currentcities);         this.set('selectedcity',  selectedcity);     },     ... });

initial setup working fine, changing country selection not update city selection in drop-down, though observer (selectedcountrychanged) called , this.set('selectedcity', selectedcity); working expected (as seen in console logging). currentcities set after observer runs, active (selected) value not correct (remains unchanged).

are there known issues programmatic update of bound properties, in case selectionbinding?

my select2selectview is:

settingsapp.select2selectview = ember.select.extend({     prompt: 'please select...',     classnames: ['input-xlarge'],      didinsertelement: function() {         ember.run.scheduleonce('afterrender', this, 'processchildelements');     },      processchildelements: function() {         this.$().select2({             // here configuration of             // select2 component             escapemarkup: function (m) { return m; } // not want escape markup since displaying html in results         });     },      willdestroyelement: function () {         this.$().select2('destroy');     }  });

check whether selected city getting displayed removing select2(replacing normal select). if that's case, selectionbinding has propagated select2.

i've plotted data points , fitted exponential curve between them using 'fit' in matlab. problem fit-function got fitted line wanted plot, markers on top of regular markers. solved problem plotting wanted markers on top of unwanted couldn't seen. problem. when want show legends dots in there. how can remove markers legend without removing fitted line since both of them hidden inside fit-function? can stop 'fit' plotting unwanted markers? so, want remove blue dot called 'hoff' in picture below. you can leave out legend-entries manually leaving out handles of lines, dont want in legend. try this: %if plot something, want showing in legend, save handle: h_line = plot(x,y) %you dont want show line? dont anything, plot it: plot(mymarker) %then set legend-> can add text legend-entries %a cell-array containing strings want show up: legend([h_line another_line],{'text1' 'text2'}) with example (see comments) came solution: ...
