Angular 2 (+Dart) inline conditionals: Is the second condition evaluated if the first is false? How to solve? -


this code in component.html (angular dart template):

<div *ngif="selectedoffer!=null && !selectedoffer.isbotenoffer">...</div>

this exception get:

exception: nosuchmethoderror: getter 'isbotenoffer' called on null. receiver: null tried calling: isbotenoffer

selectedoffer null sometimes. why second statement evaluated if first false? , how can around best?

angular write generated template file:

_ngif_0_5.ngif = ((ctx.selectedoffer != null) && !ctx.selectedoffer.isbotenoffer);

so shouldn't evaluate selectedoffer.isbotenoffer if selectedoffer null. however, may hitting bug fixed in dart2js: https://github.com/dart-lang/sdk/commit/fe7baee84828e109a49920c2572f3917e5ff8ca5

you might hit issue if setting selectedoffer in component's constructor, doing return in constructor.

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
