I created content for Touch UI, uses AEM6 and create content with help with instructions http://experience-aem.blogspot.ru/2015/02/aem-6-sp2-touch-ui-multi-field-component.html :
<categorySpotlightEntries
jcr:primaryType="nt:unstructured"
sling:resourceType="granite/ui/components/foundation/form/multifield"
class="full-width"
fieldDescription="Click '+' to add a new page"
fieldLabel="Manage Category Spotlight Items">
<field
jcr:primaryType="nt:unstructured"
sling:resourceType="granite/ui/components/foundation/form/fieldset"
eaem-nested=""
name="./categorySpotlightEntries">
<layout
jcr:primaryType="nt:unstructured"
sling:resourceType="granite/ui/components/foundation/layouts/fixedcolumns"
method="absolute"/>
<items jcr:primaryType="nt:unstructured">
<column
jcr:primaryType="nt:unstructured"
sling:resourceType="granite/ui/components/foundation/container">
<items jcr:primaryType="nt:unstructured">
<tags
jcr:primaryType="nt:unstructured"
sling:resourceType="granite/ui/components/foundation/form/autocomplete"
fieldLabel="Tags"
mode="contains"
multiple="{Boolean}true"
name="./tagField">
<values
jcr:primaryType="nt:unstructured"
sling:resourceType="cq/gui/components/common/autocomplete/taggingtags"/>
<options
jcr:primaryType="nt:unstructured"
sling:resourceType="granite/ui/components/foundation/form/autocomplete/list"
src="/libs/cq/gui/content/common/tags.html{?query,start,end}"/>
</tags>
</items>
</column>
</items>
</field>
</categorySpotlightEntries>
All runs except Tags parameter. Tags parameter value is not saved. Does anyone know how to solve this problem?
