- Open assets app
- Open thumbnail view
Only assets are shown
This is happening because when info.magnolia.ui.contentapp.browser.ThumbnailView instantiates info.magnolia.ui.vaadin.layout.LazyThumbnailLayout, it is making use of the configured info.magnolia.ui.contentapp.JcrDataProvider, which retrieves the configuration from the datasource definition, allowedNodeTypes property (mgnl:folder and mgnl:asset)
On the contrary, in the old assets app, info.magnolia.ui.workbench.thumbnail.JcrThumbnailContainer was used, which includes a specific constraint not to retrieve items of type mgnl:folder
Folder icons is use as preview for folders.
