As it usually does when there is an error in my script, missing or incorrect field names, QlikView crashes. I am aware of the problem so I always try to remember to save before I press reload. However, this time, my document (QVW file) reset completely and appeared like it was when I worked on it 2 days ago. I know I have saved the document at least 10 times today as well as having auto save function enabled with 10 min interval.
I was just wondering if this has happened to any one else. Is this a QlikView issue or is it my computer? I have of course searched through all folders on the computer, but with out any luck. Only 1 file exists and it is old.
Are there any backup documents I could search for or anything? So far I have looked for all new files created today, but can not really see any QlikView related files on my computers that would appear to be the current file or a backup file.
I have never heard about this kind of error, but since version 9 it is possible to save a qvw without data as xml file which can be stored in a versioning system like SVN. I think it is a good practice because it makes the history of the application available in addition to prevent the kind of loss you are suffering.
In v9sr4 I quite often see Qlikview client go 'not responding' when there is a script error and I have to use Task Manager to kill it.
As well as saving before a reload, under User Preferences>Save I set 'Use backup' and 'save last 6 instances' so that I can get back to the last clean reload.
Do you not back your server up as I think you may have lost your last 2 days of work?
We do have backup of course, but I had done a lot of work on the file today as well which I lost. Nothing that can not be redone, so it will just be time consuming getting back to where I was.
I will definitely use both advices in the future. Probably change version number a bit more frequently as well!
Under QV10, you can also explode a QVW out to all its component XML files. You get an XML file called AllProperties.xml which contains the overall document / sheet settings plus one XML file for each object in your QVW.
1) Create a folder below the folder with your QVW with a name the same as your QVW plus a suffix of "-prj".
2) Open the QVW and save it.
3) The XML files will now be in the folder you created in step #1.
This way you can theoretically put the XML files into Source Code control for version control and / or recovery.
