Did you try the attached project?

I tried it once more on another machine: debian stable version 5.0.3, 
libqt-mt.so.3.3.8, and gambas version 2.15.2; the error *does not* show 
up, with the edit call in the GotFocus event. I just used the project 
attached in the previous mail.

So the same project, in one of my offices with two different machines 
shows up the problem. Other users on this list confirmed the problem; 
but now, on another machine but basically the same (included the XMing 
remote X server), works well. I am getting pretty confused - but I will 
go till the end.

Apart from this, I can not see the point in your explanation. The 
GotFocus event gets executed only once, and from there the edit method 
is called. All ok - there are no problems up to now. Then, if you press 
once a cursor key, several click events fire without any further 
intervention, as the cells are traveled. So I think your explanation 
does not fit. Unfortunately, in this office the problem does not show, 
so I must wait to investigate more.

Just now, looking better at class file, I notice that the edit method is 
called once in Form_Open and once in Tableview1_GotFocus. F5... error 
11. Strange... just a few minutes ago it worked. I relaunch gambas and 
start again.

...

Well, tried several different setups - no problems. Implemented the Save 
event, and all is work as intended. The edit call can be either in the 
click event or the save event, or even the GotFocus event: it is exactly 
the same. I attach the new project, but I think that if the problem 
shows up somewhere, it is totally unrelated to the place where the edit 
call is put.

I will try better on the other office. The problem is that this kind of 
works must be done on the other office, not the one I am currently in...

Regards,
Doriano
