Symptom: customer reports any failure about the standalone version (nwds version) of the themeeditor
Answer: we don't support the NWDS version of it, SAP guarantees support only if you use the portal theme editor.
Some further explanation:
Theme Editor (NWDS plugin)
"SAP presents applications to users in the SAP Enterprise Portal (SAP EP). You can change user interface themes with the "Portal Theme Editor" that is part of the Enterprise System Administration role.
As some customers do not have the version of SAP Enterprise Portal that includes this Theme Editor , this version of the Theme Editor is offered as an unsupported, standalone tool from SDN.
Comments and questions: Please use the Web Dynpro forum. Problems regarding the Eclipse Theme Editor reported via OSS will not be handled. As the tool comes as an unsupported version, bug fixes cannot be guaranteed in a timely fashion. "
