Previews missing after updating to 1.10.0

[OwainJ]

Which Umbraco.Community.BlockPreview version are you using?

1.10.0

Which Umbraco version are you using? For example: 10.4.0 - don't just write v10

13.4.1

Bug summary

After updating to v1.10.0, the block previews are no longer shown.

There are no errors in the browser's console, or the Umbraco log.

v1.9.1 works as expected:

The above screenshots are taken from a project that uses the Block List, but I have also observed the issue on a project that uses the Block Grid.

Steps to reproduce

• Update to v1.10.0
• Observe if the previews are still shown

Expected result / actual result

No response

Thanks for raising so quickly @OwainJ! I've deprecated this version on NuGet as I have managed to replicate, but only when installed from there. Will do some digging and let you know once there's a new version out.

[rickbutterfield]

@OwainJ out of curiosity, is the doctype you're looking at primarily made up of compositions?

[OwainJ]

@rickbutterfield Yup, it is, the Block List property is from a composition.

And it's the same on my other project, where the Block Grid is also from a composition.

[rickbutterfield]

@OwainJ Thought so! Please give v1.10.1 a go and let me know how you get on 😁

[OwainJ]

Hi @rickbutterfield, unfortunately I'm seeing the same thing in v1.10.1; downgrading to v1.9.1 and they show up again.
No errors in the console or log either.

I'll see if I can recreate this on a vanilla project tomorrow and share a .zip here, although I'm on an Umbraco course in the morning, so would be in the afternoon sometime.

I am having the same issue after installing version 1.10.3 in 13.4.1. Did anyone find a solution?
Thank you

[OwainJ]

Apologies, I didn't get around to testing the new release and it completely slipped my mind!

I've just done a quick test with a fresh install and I get the same issue:

Here's a .zip of the test project: BlockPreview_1-10-3_Test.zip

• BlockPreview v1.10.3

Thanks for the test project @OwainJ! The issue here appears to be that ModelsBuilder isn't enabled. Unfortunately the package doesn't work without this enabled as it tries to strongly type the data coming from the backoffice!

I'll add a note to the README about having ModelsBuilder enabled. Is there a use case for you where you'd want to use this without ModelsBuilder? (or @katie366 - I'd be curious to see if it's the same for you!)

[OwainJ]

Ahh what silly mistake lol my bad! I have no use case, I just forgot to enable it on the test project.

I've re-tested with Models Builder enabled, and can confirm that it works with the Block Grid, but weirdly, the Block List previews seem to just repeat the preview of the first block:

Here's an updated test project with models builder enabled:
BlockPreviewTest_1-10-3_Test-2.zip

I also tested on one of my client's projects, where v1.9.1 works as expected, v1.10.1 showed no previews, and v1.10.3 has the weird repeating issue on Block List previews:

v1.9.1 screenshot

v1.10.1 screenshot

v1.10.3 screenshot

Edit: The blocklist on v1.10.2 behaves the same as v1.10.3

[katie366]

I have also enabled Models Builder, and have upgraded to v1.10.3 and have got it working. I don't have the repetition or the preview blocks.

Thank you

@OwainJ v1.10.4 is being released right now, with a fix for this!

[OwainJ]

Legend 😄 happy to report that v1.10.4 is working nicely!
