3rd Party Search Engine Integration - some property not rendering

Question

Hi,
I have tried to integrate a 3rd Party Search Engine into TREX following the published example.
I have successfully integrated and search results from the 3rd party engine are showing up.
However, some properties like cm_description, cm_contentlength, cm_modifedby are not rendering; their value are null; the search layout are specified correctly.
I only managed to set
1) cm_displayname
2) cm_contenttype
3) cm_id
and are showing up.
The setting of the rest of the properties are done in the same way and put into the propertymap.
Any idea why are the not rendering?? Any help appreciated. Thanks!

Hello Thilo,
I tried to deploy the original package com.customer.search.par, but unfortunately I got also an error with this package.
The disadvantage is, that I don't get an error message during start-up in one of the logger - for cause analysis.
I got the following error message within KM:
java.lang.NullPointerException
     at com.sapportals.wcm.repository.runtime.CmSystem.getResourceImpl (CmSystem.java:774)
     at com.sapportals.wcm.repository.runtime.CmSystem.getResource (CmSystem.java:325)
     at com.sapportals.wcm.repository.runtime.CmAdapter.getResource (CmAdapter.java:81)

     at com.sapportals.portal.prt.core.broker.PortalServiceItem.__initServiceInstanceStep2(PortalServiceItem.java:736)
What can I do at this point?
Best regards,
Walter
