Hello
I have some problems with the databasee connections.
I create a new connection and check the box for "Use default application connection". Then I type in all information like Server, User and so on. If I now check the connection everything seems fine but when I create the connection the Symbol (the wire-button (dont know how to call it)) says that i am not connected. When i now pusch the Button or try to render a report the LRDesigner craches and I get a core file. Is this a bug or do i something wrong?
-
I'll check it
-
Which database server do you use?
-
Hi,
it is an Oracle (Release 12.2.0.1.0) database.
Hope this is the answer you where looking for.

I don´t know if it helps, but I get the message "~QOCIResult: unable to free statement handle". Dont know if it is related to this problem or if it is another problem, but in the moment I have many problems with the database connection. :-\

Hi
I have made some changes in the database connection.
Would you get the latest version of limereport from github and check it?
-
Yes I will try it, but I have some issues with the installation of the previous version on a system with QT4. There is no problem on the system with QT5. But in this case I need QT4.
I get this message:

Is it possible that I can use the new limereport also on a QT4 system?
Paul

Sure
The QTabWidget hasn't public function QTabBar *tabBar() in Qt 4.x
http://doc.qt.io/qt-4.8/qtabwidget.html
But there is Protected function
To Alex: may be need to inherit from QTabWidget the class for compatibility?
-
Subst Yes i did it :)
Paul Traut I will fix qt4 build soon
-
Wow thanks,
this is realy fast
-
Paul Traut
Done
You can get version 1.4.49 and check it
Development branch also has been fixed
-
I will check it soon, have to wait for some help here ;D

Ok, I have checked the database connection.
Here is my result:
1. the default connection is more stable than before (means it crashes not directly, when i try to push the connect button) but it still crashes after some times.
2. the connect button still stays on "not connected" even if the connection is established.
3. when I delete a connection (default or another) all remaining connections cannot be edited, all the buttons for editing stay gray when I select a connection.
Had no time to check it further, will do this in one week, because I will have holiday for a week.

Have a nice holiday :)
but it still crashes after some times
How it's happen? You push the connection button several times and designer is crashed?
