Error while calculing item height

[mbernard]

@martingust
The virtual-repeat.for doesn't load anymore. It seems that there's always an empty element in the DOM as first child in the repeat and it make the calculateHeight to crash with an error as the height is 0. I don't know why there's always an empty element inserted before the elements that should be renderer. If I use the non virtual repeat.for there's no extra elements. (See screenshot)

HTML template

DOM with the extra div element inserted by the virtual-repeat.for

Looks like a problem when iterating to empy array. Will look into this.

@martingust I've tried many things.

• Empty array
• Array with 1 element
• Array with n elements

In every case I have an empty dom element

@mbernard I've just tried installing virtual-repeat in a fresh skeleton-navigation and it worked well. Are you up to date with all dependencies and have no forks? Also if possible can you provide some steps on how I can reproduce this, ideally in skeleton navigation.

[martingust]

@mbernard Is this still an issue? New release got out yesterday.

[mbernard]

@martingust Yes, I'm having trouble reproducing the issue in the skeleton though. I'm workin on it.

I found something that looks like the same error but I'm not sure it is.

If you use a virtual-repeat.for on a <ul> with "list-style: none" it seems to cause the same error

[martingust]

@mbernard Any update on this? I tested run UI-Virtualization sample app with ul and list-style: none and it seemed to work fine.

[mbernard]

@martingust I'm sorry, I'm on a super tight schedule for a project and I had no time to dig the issue further. The virtualization was more a nice to have for us, so I put it aside for the time being. I'll try to build you a repro case as soon as I have some free time :D

[martingust]

@mbernard I'm sorry you had to put it a side. Please re-open this when you get a repro together and I'll look into your issue. Thanks!
