How to Modify the Year Range in the Content Services UI Page Drop-downs

1. Go to adobe-contentservices.ear\contentservices.war\WEB-INF

2. Open faces-config-custom.xml

3. Copy paste the following in the file

<managed-bean>
      <description>
         Bean that generates a date picker component
      </description>
      <managed-bean-name>DatePickerGenerator</managed-bean-name>
      <managed-bean-class>org.alfresco.web.bean.generator.DatePickerGenerator</managed-bean-class>
      <managed-bean-scope>request</managed-bean-scope>
      <managed-property>
         <property-name>startYear</property-name>
         <value>2020</value>
      </managed-property>
      <managed-property>
         <property-name>yearCount</property-name>
         <value>60</value>
      </managed-property>
      <managed-property>
         <property-name>initialiseIfNull</property-name>
         <value>false</value>
      </managed-property>
   </managed-bean>

It should give you a default range of 60 years (1961-2020) across all calendar components.
