CL_GUI_ALV_TREE - Illegal Event Combination (selection_changed + link_clicked )

[former_member804181]

Hey,
I have a dynpro with 3 custom containers, each of these contains an ALV control. The one of the left is an instance of cl_gui_alv_tree the other 2 are instances of cl_gui_alv_grid.

On the tree I have registered the event 'selection_changed' to dynamically alter the output of the alv grids whenever the user makes certain changes in the node selection. This functionality is essential for the program.

Now I had the idea of implementing a nice additional (non essential) feature. Whenever the user clicks on certain leaves (which should be designed as links), I want to use the function 'RS_TOOL_ACCESS' to delegate the user to the class the leaf represents. For that I wanted to register the event 'link_click' on the tree.
However combining 'link_click' and 'selection_change' is not possible obviously. This seems to be due to the 'item_selection' parameter that is set in the constructor of 'cl_gui_alv_tree'. For 'node_seletion' to work it has to be set false, for 'link_click' to work, it needs to be true.

Is there a way around this limitation ?

Thank you in advance !

CL_GUI_ALV_TREE doesn't work very well. For instance, the combination of item_selection and context menu fails too. If you don't need the ALV features of CL_GUI_ALV_TREE, you may use directly the GUI control it's based on, which is CL_GUI_COLUMN_TREE.

Thank you for the answer. I decided pro gui_alv_tree and against one of the tree controls, because it seemed like integrating a toolbar is more of a hassle with the latter (maybe I judged wrongly). If I had known about the limitations of gui_alv_tree, maybe I would have decided differently.

My "work around" consists of not using 'selection_changed' anymore, but instead work with buttons and links.
