doubt in external context mapping

28 Views

Hi,

whiel practicing the external context mapping exmaple i read the following lines in the PDF file

"At design time, a Web Dynpro component does not know the context structures of its

embedding Web Dynpro component. Therefore, it is not possible at design time to map

context elements in the component interface controller of Web Dynpro component A to

context elements that belong to a controller context of Web Dynpro component B, which has

declared a usage of A. However, if Web Dynpro component A itself uses another Web Dynpro

component within itself, this is possible (general context mapping)."

I could not understand the difference between the second and the third lines Can any one let me know if at all there is any difference? Also i would want to know the reason behind such restriction as to y the parent cant red the context of the child component?

Also can any one let me know the reason y cant we do the external context mapping for the attributes of the root node?
