> URL: http://jira.magnolia.info/browse/MAGNOLIA-1465
> Project: Magnolia
> Issue Type: Improvement
> Components: core, gui
> Affects Versions: 3.1 M1
> Reporter: Oliver Lietz
> Assignee: Teresa Miyar

>
> lets you save and get properties with multiple values
> To save a property with multiple values you need a custom SaveHandlerImpl
> (this is java5 for client project):
> protected void processMultiple(Content content, String name, int type,
> String[] strings) throws RepositoryException,
> PathNotFoundException, AccessDeniedException {
> List<Value> values = new ArrayList<Value>();
> NodeData data = NodeDataUtil.getOrCreate(content, name);
> if (strings != null && strings.length != 0) {
> for (String string : strings) {
> Value value = getValue(string, type);
> if (value != null) {
> values.add(value);
> }
> }
> data.setValue(values.toArray(new Value[values.size()]));
> } else {
> data.delete();
> }
> }
> So there should be a switch for multiple nodes and multiple values later in
> related classes.
> XML export looks like so:
> <sv:property sv:name="product:colors" sv:type="String">
> <sv:value>black</sv:value>
> <sv:value>blue</sv:value>
> </sv:property>
