Clear context in Web Dynpro

[Former Member]

Hi,

I have created a table based on search crieteria.

The scenario is first time e.g user has given some selection, it will return 5 records. These 5 records will be displayed in the table.

Now, if user enter some selection, which does not return any record, in that case i'm displaying the error message.

For displaying the message, i'm using get_element_count method, if it's > 0, then it displays the table else display the error message. But the problem is even in second time, if there is no record return, get_element_count mehtod return 5 records of the first search.

How to clear the context, or how to proceed. I can change my condition for a temp solution, but pls let me know what is the best way to do this.

Thanks,

Remove context is different from the Context change.

Remove context does, it removes all the upper nodes of that particular node

where as Context change is used to set the context for that particular fields to satisfy the conditions
