Hi all,

When adding tag provider as source filter on the perspective alarm list I see everything for about 1 or 2 seconds when the view is loaded in the browser. Moments later the filter is applied.

Is there any work around for this? Thanks in advance.

Nah, we where only able to tweak it so that the full list was visible for a shorter time.

Is the `source` filter prop a binding to something ?  
I found that for several components that display a lot of things that get filtered, the time needed to evaluate the binding sometimes caused the full list of things to be displayed for a short amount of time.  
We disabled the bindings and the problem was gone. If you still need those props to be dynamically computed, you could try preprocessing them somehow before the component is loaded.

Try hardcoding it and see if it’s faster. If it is, then it’s time to try and figure out a way to get rid of the binding ;p
