I was trying to reduce my app by bookmark. Got, error something like: 'Error: Failed to generate QVW files.. Exception=System.ArgumentException: Empty path name is not legal' . After a couple of alternate tries, I found that if I remove all my 'Always One Selected Value' from list boxes, the issue goes. Is this a known issue? Bug (QV 11 SR2) ? I would appreciate and thank for any shed of light on this.
I'm not sure if it's a bug. I think what qliktech would say is that is the expected behaviour, however it is kind of annoying. The problem is that you can't clear or override selections made by a one-selected value.
For example let's say you have a listbox containing Continent dimension and the selected value is let's say "Europe". Then if you have another listbox with Country Dimension and you try to select a country that is not in Europe, like Mexico (in other words that is not within possible values), then that selection in country will be disregarded because the one selected value has more hierarchy/importance/precedence or whatever you want to call it.
This is an issue that affects any process that include looping over possible values (like reduction, or even external apps like NPrinting),
Thanks Erik Gustafsson for your response. I am in touch with support(through my partner. This is another pain area that I can't directly contact Qlik support) and expecting a reasonable feedback. It seems a bit dicey. There has to be a pattern that can be found out - how qv is actually behaving. I have done couple of testings as in attached.
However, my live application(with much more data) shows a different error: '...Empty path name is not legal'.
Qlik has many direct customers, but in your case your license is acquired through a partner, which is why they should provide first level support according to a contract between the partner and Qlik Support.
An investigation might become a bit long to maintain here, which is why it might be worth reaching Qlik Support to get an in-depth analysis. One needs to analyze Task and DocumentLogs, QDS logs and a sample document in order to reach a full conclusion.
