handle_double_click

Former Member — Tue, 18 Nov 2008 05:25:56 GMT

Dear All,

I am using the method handle_double_click to navigate to a new ALV list when the user double clicks a certain row.

My issue is, when I double click one row, the details are output in a separate list, its fine. When I press the back button and double click a different row, the result displayed in the second list is always the previous one, its not changing with selection of a different row.

Please tell me how to get around this issue.

Regards,

Prosenjit.

The issue was, when we are displaying for the first time in the secondary ALV list, the instance of the class cl_gui_alv_grid is initial.

However when we go back and select a different row, the secondary ALV list's cl_gui_alv_grid instance is not initial anymore, so in the ELSE part we have to call second_instance->refresh_table_display.
