lead selection has not been set

[Former Member]

Hi,

I have some error in webdynpro :The lead selection has not been set. MAIN

If the cardinality of your node is 1..N or 1..1, then the runtime expects your context to have atleast one element. In this case, if you have no elements and the check box "Initialize lead selection" is set to true, then it will fail because there is no element to be selected. Instead, if the cardinality is 0..N or 0..1, then it is possible that the context node can be empty. And when there are elements, the first one will be selected if the lead selection check box is checked.

So if you will have an empty context node initially (i.e if you do not do a bind_table in wddoinit), then select the cardinality of your node as 0..N. This will avoid such a dump.

Hi

In your Context Node make sure that the context node you have used in the layout have the property

Initial Lead Selection check box ticked.

And

Also the Context Nod is not Empty.

Hi Abhi,

My context node already ticked.

Hi

So, your context node is empty.

Make the cardinality to 1..n
