Release Notes Summary:
The function nx:arrayContains is added to evaluate JSF EL condition on multi-valued properties.
Release Notes Description:
Hide

Added new functions in the EL context to work with arrays:

nx:arrayContains: returns true if the given array contains the given element.

${nx:arrayContains(array, 'foo')}

nx:arrayContainsAll: returns true if the given array contains all the given elements.

${nx:arrayContainsAll(array, 'bar', 'foo')}

nx:arrayContainsAny: returns true if the given array contains one of the given elements.

${nx:nx:arrayContainsAny(array, 'bar', 'foo')}

nx:arrayContainsNone: returns true if the given array contains none of the given elements.

${nx:arrayContainsNone(array, 'barfoo', 'foobar')}

For instance, those functions can be used in filters to filter picture conversions:

<extension target="org.nuxeo.ecm.platform.picture.ImagingComponent" point="pictureConversions"> <pictureConversion id="subjectFilteredConversion" maxSize="200"> <filters> <filter-id>subjectFilter</filter-id> </filters> </pictureConversion> </extension> <extension target="org.nuxeo.ecm.platform.actions.ActionService" point="filters"> <filter id="subjectFilter"> <rule grant="true"> <condition>#{nx:arrayContains(currentDocument.dc.subjects, "art/paint")}</condition> </rule> </filter> </extension>

Description

Filters can be applied to picture conversions as described in [HOWTO: Contribute Picture Conversions|Transactions and Connections]. When using a condition, it is impossible to test if a String multi-valued property (e.g. dc:subjects) contains a value (e.g. art/paint).

How to reproduce:

define a new picture conversion and its filter:

<extension target="org.nuxeo.ecm.platform.actions.ActionService" point="filters">
  
  <filter id="my-subject-filter">
    <rule grant="true">
      <condition>#{ currentDocument.dc.subjects.contains("art/paint") }</condition>
    </rule>
  </filter>

</extension>

  <extension point="pictureConversions" target="org.nuxeo.ecm.platform.picture.ImagingComponent" >

    <pictureConversion chainId="Image.Blob.Resize" default="true" description="Thumbnail size 2" id="Thumbnail2" maxSize="100" order="0" rendition="true">
      <filters>
        <filter-id>my-subject-filter</filter-id>
      </filters>
    </pictureConversion>

  </extension>

deploy
create a Picture document and set subjects to Art / Paint

Expected result: picture view Thumbnail size 2 is generated.
Actual result: picture view Thumbnail size 2 is not generated.

I know that JSF EL expression currentDocument.dc.subjects returns an array and method contains cannot be called on it but there is no available way to test if property dc:subjects contains a value.
