Support mulit-value type hints (eg. @TypeHint=String[])
-------------------------------------------------------
Key: SLING-533
URL: https://issues.apache.org/jira/browse/SLING-533
Project: Sling
Issue Type: New Feature
Components: Servlets Post
Reporter: Alexander Klimetschek
As discussed in SLING-522, when posting a single value to a property that
should be multi-valued, an extension to the @TypeHint is needed that allows the
explicit definition of a multi-value type. For example, for Strings this would
be @TypeHint=String[].
Based on a quick look at the code, it should happen in
o.a.s.servlets.post.impl.helper.SlingPropertyValueHandler.setPropertyAsIs().
First of all the parsing of the getTypeHint() must be changed to look for an
ending [] first, and then this "isMultiValued" information must be used to call
the multi-value version of setProperty() in all cases (values.length >= 0).
