Issue

  • Below error was encountered while trying to use the 'Dynamic Query' in custom code:
     
    ERROR [http-nio-9090-exec-9][DynamicQueryFactoryImpl:83] Unable find model com.liferay.portal.workflow.kaleo.model.impl.KaleoInstanceTokenImpl
    java.lang.ClassNotFoundException: com.liferay.portal.workflow.kaleo.model.impl.KaleoInstanceTokenImpl
  • Usage of Dynamic Query in KaleoInstanceToken:
     
    // Create a dynamic query for KaleoInstanceToken
    DynamicQuery kaleoQuery = DynamicQueryFactoryUtil.forClass(KaleoInstanceToken.class, "kaleoInstanceToken", PortalClassLoaderUtil.getClassLoader());
    kaleoQuery.add(PropertyFactoryUtil.forName("classPK").eq(formInstanceRecordVersionId));
    kaleoQuery.add(RestrictionsFactoryUtil.eq("companyId", companyId));

Environment

  • Liferay DXP 7.4

Resolution

  • There is no method declared related to the use of dynamic Query in the KaleoInstanceTokenUtil.java class.
    Refer: KaleoInstanceTokenUtil.java
  • To create the dynamic query, use the below method, which is present in this class (KaleoTaskInstanceLocalServiceUtil.java):
    public static DynamicQuery dynamicQuery() {
    return getService().dynamicQuery();
    }
    Refer: KaleoTaskInstanceTokenLocalServiceUtil.java
