Double click second time on ALV Tree node, leading to short dump.

[Former Member]

Hi All,

I have a strange problem in ALV tree.

In my program I have 4 nodes as following.

->Others

->Original

->Doc1

->Doc2

I'm using "CL_gui_alv_tree" to display the above list.

Now requirement is to dispaly a tick mark(icon_checked) beside original, Doc1 & Doc2. Tick mark(icon_checked)

beside Original is constant it will not change, but at any given point of time tick mark(icon_checked) should be there either for Doc1 or Doc2, but not both.

Lets say if user click on Doc1 then tick mark(icon_checked) should be displayed next to doc1 and it should be clear beside doc2.

similarly if doc2 is double clicked, then tick mark(icon_checked) should be displayed next to doc2 and removed beside doc1.

I'm able to meet this requirement using the event double click and method change_node & frontend_upate.

Now the probelm is.

when the list is displayed for the first time. There will not be any tick mark(icon_checked) beside doc1 or doc2, it should be displayed next to Original only.

Now if I doubel click on doc1 for first time, it displays icon next to it,

when I double click on Doc2 for first time, its placing icon next to Doc2 and removing from Doc1.

Again when I double click on Doc1 for second time, its placing icon next to Doc1 and removing from Doc2.

Again when I double click on Doc2 for second time, its leading to short dump and Error is as follows.

" A RAISE statement in the program "CL_GUI_CFW====================CP" raised the

exception

condition "CNTL_ERROR".

Since the exception was not intercepted by a superior

program, processing was terminated. "

No matter how many times i double click on Doc1, i'm not getting this error. But only on Doc2 node for the second time, i'm getting this error.

I cant say its presentation server error, all other tree program are working fine in the system.

Please share your views.

Thanks in Advance.
