when Interface node is used without input Element(Ext.) in Webdynpro component.

[former_member278566]

Hi All,

I have created a webdynpro component and i want to use this webdynpro from another webdynpro.

Suppose the webdynpro name is parent and child webdynpro.

I want to use child webdynpro in parent. To Facilitate that i need to create interface view and interface context in child webdynpro.

My question is all about context in child webdynpro. I need to declare one of the node from component controller as interface note and it should be visible in parent. But unfortunately it is not available in parent until i define it as input Element(Ext.).

Can anyone please explain what is the use iof interface node without input ext.

Hi Rajeev,

The input Element (Ext) can only be used if you are using interface node.

There can be two cases where you use interface node.

a) if you want to supply data from component A to component B.

b) if you want component B to send back some data to component A.

for the first case interface node is enough, but for second case it should be input element (ext)

inorder to use the input element ext property , the node should be interface node , else it will show the below message and it will not allow.

Rewards if useful.
