While developing my app I bumped into as believed unusual problem. I assigned functions into variable (in my case to get sub-string from selected field) and it worked perfect till yesterday... Randomly, the variable gets null value when different element of list box (on which functions are based) is selected. When I click clear button, the variable reset to correct value. Functions printed in text object always work fine. So I created clear all trigger on my list box when selected, but it didn't help. I will be very grateful for any idea which could solve the problem.
I owe an explanation to Qlik Community After loading my app on server the problem, which I described simply disappeared. Therefore I assume it was general the problem with memory capacity; since I implemented vast number of variables it was hard to refresh values to all of them via desktop Qlikview.
