How can we access the context of Parent's Component Controller

Good day,

I have 3 components named MainComp, TaskComp and ObjectComp.

TaskComp has context node 'Tasks' and view 'TaskView'.

ObjectComp has context node 'Objects' and view 'ObjectView'. They both are defined as interface nodes.

Both TaskComp and ObjectComp are being defined as Used Component in MainComp and so their nodes are mapped to the context of MainComp, so now MainComp also have two context nodes Tasks and Objects.  The views TaskView and ObjectView of the components TaskComp and ObjectComp has also been embedded in the window of MainComp. Now Table element is used to enter the data in the both TaskView and ObjectView which are bound to nodes 'Tasks' and 'Objects' so data are being populated in them. Now I want to access the context node Objects in method of TaskComp i.e. I want to access Parent's(MainComp) Component Context Nodes in TaskComp method. Can someone please help me out by mentioning the code needed to access the parent's component context. Is it also possible to access directly the context 'Objects' using ObjectComp instead of MainComp, if it is, then please also do mention the code required.

Thanks and Regards,

Talha
