Title: Nested Decks cause serious lag in Report Studio
Post by: rmill9681 on 28 Jun 2016 02:59:50 PM
Hiya,
I'm creating the layout/UI for an active report.  No queries yet.  I'm using tables to create the spacings and I have 4 levels of decks. 

Top to bottom:    Product (3 cards) -> Time Period (2 cards) -> Payment Type (2 cards) -> Chart Type (5 cards).

I'm building one branch of Product (card 1 of 3), which has the decks above nested within.  As I add the lowest level Chart Type deck, Report Studio becomes slow to respond (15-20 seconds between click on an object and response from Report Studio).  I've tried to break Time Period, Payment, Chart into separate pages and use a layout component reference, but still has lag.  There is no problem running and using the report.  Just a serious lag in Report Studio which makes development impossible.

Oddly enough, it works fine in Firefox.  However, I'm not allowed to use Firefox on development machine.  Currently using IE9, but IE11 exhibits same issue on my VM.

Any thoughts?

Seems it is related to using % in size & overflow in combination with nested decks. 

Originally:
   Used fixed size (px) in outer block and all objects within used % for width and height.  Inserted decks as noted above.  Once I inserted the 4th level, Report Studio would stop or slowly respond to button clicks.  Report runs and interacts fine.

Now:
Don't care about spacing/sizing, just drag blocks and tables into rough layout that matches the former layout I was trying to achieve.  Inserted decks just as before.  No lag at all in Report Studio.

Slowly added fixed dimensions (px) to all objects.  No lag.

In case others are having more rendering issues, one thing to also consider is conditional formatting, or any display properties for that matter that require Cognos processing post-render.

Hi,

Are these nested data decks? Is there any reason you are nesting them rather than using a single data deck driven by all four data items?
