Objects in minimized Containers are calculated

jfkinspari — Sun, 11 Aug 2013 19:29:41 GMT

Hi all,

I have an issue with an application being slow to change between tabs.

Every tab contains besides a few listboxes several containers. Each Container consists of 4-5 to obejcts in the form of either Straight Tables og Graphs. Some of the containers are build up with two container layers, that is a container inside a container.

So here's the weird part. Alle the containers are minimed by default, so when changing to a tab, there really shouldn't be anything to calculate. Even so it takes around 30 sek before the change is completed.

I've anylyzed the .mem-file, and it tells that the objects inside the minimized the containers are taking up calculation time.

Can anyone tell if this behaviour is normal, and perhaps give a solution to eliminate the calculation time?

Yup I think that's fairly normal. As a workaround to prevent calculations unless needed, I place a calculation condition on selection of a primary field/parameter such as date. Hope this helps.

It's just seems to be a ineffective behaviour. Why use time to calculate objects, that are minimized to the user? The user might not ever maximize the container or select the given object within the container.

Thank you for the idea.

I share the same sentiments brother. Perhaps Qlikview's intention is to save the user some time from on-the-fly calculations as switching between objects take place.
