"lastModified" column in Document Pickers


We implemented Image Picker sort by date to show a lastModified column in image pickers, but it isn’t obvious which cms configuration to override to do the corresponding thing to documents.

Do we update /hippo:configuration/hippo:frontend/cms/cms-folder-views/hippostd:folder/defaultColumns (and override DefaultListColumnProviderPlugin)?

If we didn’t want to override ALL document pickers and instead wanted to limit it to a specific document type/picker, how would we do that?


Yeah, it seems like so. One thing to note is that org.hippoecm.frontend.plugins.cms.browse.list.DefaultListColumnProviderPlugin doesn’t add lastmodified column by default, so you might need to copy some from org.hippoecm.frontend.plugins.gallery.columns.ImageGalleryColumnProviderPlugin and adjust it for documents.

From the child node names under /hippo:configuration/hippo:frontend/cms/cms-folder-views, it looks like the picker is determined by the folder node’s type. There is a chance you can easily add one more configuration for a custom folder node types, but I haven’t tried it. It will increase complexity as well.

Or, as it adds org.hippoecm.frontend.plugins.standards.list.ListColumn instances for columns in the end, perhaps you can try to override ListColumn#addCell(Item<ICellPopulator<T>>, String, IModel<T>) to display or not to display somehow?

It seems like quite an effort of customization. :wink:

One possible strategy is, if necessary, that you might want to consider generalizing the features with configuration options and contributing to the (community) hippo-cms project – CMS JIRA ticket and patch(es) – and ask for reviews and merge for future version. If accepted, you will be future-safe.

Just my two cents,
