Reloads and macros may fail after an upgrade from QlikView 11.20 to later versions.
A complete list of symptoms include:
- Expression editor may throw an error
- Chart may show empty
- Chart may show "Incomplete visualization"
- Chart may show "Invalid dimension"
- And any other odd behavior that would mimic a change in the script (expression, set analysis, etc)
- Macros cannot be reloaded
Environment:
A new script reload mode has been introduced: BNF. This requires scripts to be modified to match the BACKUS-NAUR FORMALISM.
BNF mode can be temporarily disabled in QlikView versions prior to November 2018 (12.30). Any later release require scripts to be correctly rewritten.
Only applicable prior to 12.30:
All the flags mentioned below are disabled in 12.30 and later.
Disabling BNF reload mode on the local QlikView client:
Update the QV.exe Settings.ini file by adding the line EnableBnfReload=0 under the [Settings 7] tag for the default reload setting "EnableBnfReload".
By default, Settings.ini can be found in C:\%USER%\AppData\Roaming\QlikTech\QlikView?
Disabling BNF reload mode for the entire server :
Update the QVB.exe Settings.ini by adding the line EnableBnfReload=0 under the [Settings 7] tag for the default reload setting "EnableBnfReload".
By default, the Settings.ini can be found in C:\Windows\System32\config\systemprofile\AppData\Roaming\QlikTech\QlikViewBatch. For more information please review Where to find the QlikView QVB settings file
Modify it to read:
[Settings 7]
EnableBnfReload=0
Disabling BNF reload mode for individual apps:
Add the ///$bnf off tag at the top of the script (it must be within the first 50 characters of the script). Reload the script.
It is a good idea to use the ///$bnf off tag as a troubleshooting step. See if toggling this setting in the load script will cause a change in the suspect behavior.
