hi,

if you want to access component controller's method's in view then use the following coding

wd_comp_controller->method name().

but the back navigation that is a method from view cannot be called into component controller.

2.if a context node is created in component controller then the data in the node gets shared whereever you drag and drop the context in view but reverse mapping from view to component controller is not possible as whatever context or methods are created in view they are local to the view.

Hello,

1) To call a method from component controller in the view use:

 WD_COMP_CONTROLLER->method();

You can get more help about this in [Web Dynpro Runtime APIs|http://help.sap.com/saphelp_nw04s/helpdata/en/61/497941761b070de10000000a1550b0/frameset.htm]

2) You can't use a view context in the component controller, declare the context in the component controller and in your view use a mapping to this.

Hi,

I want to call a method in view from controller ? 

It is not possible to call view's method from component controller.

how I can access the context of view in the controller ???

You can't access the context of view in component controller unless they are mapped together. To map them create context in component controller and then go to context of view controller and drag & drop the context nodes which you want to map. Now you can access these context in view as well as component controller.

I hope it helps.
