BUG Reload content in raw content mode is broken

[thetechnick]

Hey Neos team,
I am checking out Neos for a project and am trying to understand the demo/example site.

Seems like going through the docker flow:
https://docs.neos.io/guide/installation-development-setup/docker-and-docker-compose-setup

Will result in a demo page where you cannot create new Text nodes directly within the Main content area, although they are used in a few places without being contained within a column content wrapper.

Trying to create a new Text node within a column content will result in an error:

Neos\Neos\Fusion\Helper\ArrayHelper::sortByPropertyPath(): Argument neos/Neos.Demo#1 ($set) must be of type array, null given - Check the logs for details

The container logs just show accepted connections, so I am not quite sure where Neos is logging to for the detailed error description.

Found the logs :)

Thanks for attaching the log. It seems youre using the newer-ish raw content mode of Neos in the Ui rather than the 'normal' edit mode.

And this line:

neos-development-collection/Neos.Neos/Resources/Private/Fusion/RawContent/NodeProperties.fusion

Line 4 in f15a8c0

[email protected] = ${Neos.Array.sortByPropertyPath(value, 'ui.inspector.position')}

Causes an error as node.nodeType.properties seems to be NULL.
I had this error on my todo stash - at least for the upcoming Neos version 9 which is still in beta.

Or are you using Neos 8 and its also a problem there?

[thetechnick]

I am a total Neos Noob, I just followed the docker example and ended up with: UI version: 8.3.11
Checking out Neos 9 is next on the todo list.
Good to hear a fix is already on it's way!

(Also: dang you guys are fast responding - here and in slack)

I had a look into this and it is related somehow to OutOfBandRendering. A full page reload works fine.

For some reason, during OutOfBandRendering there is no node in the context, which causes issues in different places.

1. neos-development-collection/Neos.Neos/Resources/Private/Fusion/RawContent/NodeProperties.fusion

   Line 4 in adb6713

   [email protected] = ${Neos.Array.sortByPropertyPath(value, 'ui.inspector.position')}

2. neos-development-collection/Neos.Neos/Resources/Private/Fusion/RawContent/NodeChildren.fusion

   Line 3 in adb6713

   children = ${q(node).children().get()}

Tested with Neos 8.3 latest dev

Thanks @dlubitz in that case there are two bugs :D one for Neos 8.3 (that i didnt know) and another for 9.0 :D
