Refresh simple tree

[former_member304579]

Hi everybody!!

I made a dialogscreen with two controls:

on the left side a simple tree <b>(CL_GUI_SIMPLE_TREE)</b>

and on the right side a ALV-List

By double clicking on a tree-node I show details in the ALV-List. After confirming changes in the ALV-List the icon for the clicked node has to change.

Everthing is working well.... only the tree-list don't like to change.

In the <b>PBO</b>- I refresh completely my node-table - update it with the <b>"update_nodes"</b> method

- and tell to the control to do the update with the <b>"set_screen_update"</b>]method.

But nothing happen!!

Do anybody has an idea what goes wrong??

Thanks for any suggestion or help.

Here my code in PBO:

REFRESH node_table.

PERFORM build_node_table USING node_table.

CALL METHOD g_tree->update_nodes

EXPORTING

node_table_structure_name = 'MTREESNODE'

node_table = node_table.

CALL METHOD grid1->refresh_table_display.

CALL METHOD g_tree->set_screen_update

EXPORTING

UPDATE = 'X'

EXCEPTIONS

failed = 1

cntl_system_error = 2.

If still somebody is interested:

I erase all nodes with tree->delete_all_nodes and construct the tree again with the new values...
