Tags inside multifields

Hello,

I created in dialog a new multifields with text and tags field into the form.

I tried to select and save more than one tag inside the multifileds without succeed.

I notice that if I put the tag outside the multifields, everything works fine.

Below my code:

<tags

cq:showOnCreate="{Boolean}true"

jcr:primaryType="nt:unstructured"

sling:resourceType="cq/gui/components/common/tagspicker"

allowBulkEdit="{Boolean}true"

allowCreate="{Boolean}true"

cq-msm-lockable="cq:tags"

fieldLabel="Tags"

name="./cq:tags"  />

<geolocalizedText

  jcr:primaryType="nt:unstructured"

sling:resourceType="silversea/silversea-com/ui/components/foundation/form/multifields"

fieldLabel="Geolocalized Text">

<field

jcr:primaryType="nt:unstructured"

sling:resourceType="granite/ui/components/foundation/form/fieldset"

class="multifields-wrapper"

name="./geolocalized"

    <items jcr:primaryType="nt:unstructured">

<text

jcr:primaryType="nt:unstructured"

  sling:resourceType="granite/ui/components/foundation/form/textfield"

fieldLabel="Text"

name="text" />

<tags

cq:showOnCreate="{Boolean}true"

jcr:primaryType="nt:unstructured"

sling:resourceType="cq/gui/components/common/tagspicker"

allowBulkEdit="{Boolean}true"

allowCreate="{Boolean}true"

cq-msm-lockable="cq:tags"

fieldLabel="Tags"

name="tags"  />

</items>

</field>

</geolocalizedText>

The green one works with this output in crxde

cq:tags            String[]                 geotagging:eu, geotagging:as, geotagging:uk

The yellow one doesn’t work, it saves only the last selected tag:

geolocalized     String                {"text":"lblj","tags":"geotagging:uk","tags@TypeHint":"String[]","tags@Delete":""}

How can I possible to achieve my goal ?

Is there any workaround ?

Thanks
