content.contentScopeFilter.addElement(c,dispatchEvent);
content.contentScopeFilter.dispatchEvent(new
Event("layoutNeeded"));
Why are you referencing content.contentScopeFilter instead of
this.contentScopeFilter ?

Subject: Extend component mxml
Hello, let's see if anyone can give me “some clue” about my problem:
I have made many “base components” “.as” that I have then extended in several
mxml with success; Now I wanted to extend an mxml and I am having problems "add
components" because when "override addElement" is executed, in the extended
mxml component, the mxml elements that I use as a template are not yet created.
I'll give you an example because I don't know if I'm explaining myself well:
Success case, ".mxml" extended from ".as":
// ---- ModuleAssignTargetToScopeSectionContent.as

public class ModuleAssignTargetToScopeSectionContent extends SectionContent {
import com.xxx.xxx.models.ConfigModel;

The problem, as you have surely guessed, is that in
“AssignTargetToScopePerson2.mxml” the elements of the extended component
(viewsAssign:PanelAssignScopePersonFilter,…) are added before the elements of
the base component (content, contentScopeFilter,…)
How should I do it?
Any example I can investigate in the SDK?
If you see any “aberration” in the lines I have attached, please tell me 😝
Any help would be appreciated.
Thx.
