Question

dynamically create a viewstack component from code

Asked by: rombooth

Dear all
I try to create a flex component test that is made out of a canvas component - only child is a viewstack with two views: two other components B and C.

From the main application I try to instantiate the component A. When I analyse the created component In debug view I only see the component created - the viewstack and its children are not created. What is going wrong? I expected that the full component is instantiated or at least the viewstack with one child (when creationPolicy is not set).

Thanks in advance for your help.

None of testc's children will be created until you add it to the main app as a child

                private function clickhandler (event:Event):void
                {                      
                        var test:testc=new testc();
                        addChild( test);    // test's children get created now
                }

You will have to set the creationPoilcy of testc to "all" as well as the ViewStack named app if you want testcc and testccc to be created at that moment too
