[opencms-dev] XmlContent & Mapping on "Assign categories", howto

[Paul-Inge Flakstad]

Hi Sandrine,

Not quite sure what you're asking, but to enable assignment of categories when editing the structured content, you need to do something like this in your XSD:
1. Define the category element, e.g.: <xsd:element name="Category" type="OpenCmsString" minOccurs="0" maxOccurs="20" />
2. Define the layout, e.g.: <layout element="Category" widget="CategoryWidget" configuration="onlyleafs=true|property=category" />
3. Define the mapping, e.g. <mapping element="Category" mapto="propertyList:collector.categories" />

The mapping is especially important. I've never tested it myself, but you should be able to place the category selector in a nested element. However, I don't think you can have one category selector in one element, and then another category selector in another element and expect that to work. (It would probably appear to work, but I don't think the mapping would survive like you'd want.)

Hope this was of some help to you.

Cheers,
Paul

Hi all !

I have a question about category fields on xmlcontent.
I know that, with a VfsFile field with CategoryWidget directly in my type xsd, this field content is mapped on categories stored when we do "Assign category" in context menu.
I'd like to use a similar category field which is in a nested XSD in this type XSD, like the Xpath /ID/Category, for mapping this value.
Can I do that and how?

Thanks in advance.

(I'm on OpenCms 8.0.4 / 8.5.0)

Sandrine.
