Help at Alias Attribute Mapping
I need some help with the Alias Attribute Mapping.
I want to map an Attribute from an Instance of the WT-Part to the WT-Document.
The Attribute only exists on the Instance "Article" on my WT-Part.
I have tried different Types of mappings so far, but I always get an error.
Here the three main attemps:
describedBy@wt.part.WTPartDescribeLink~describes^com.test_fuchs.article~ARTICLE_DESCRIPTION_DE^wt.part.WTPart
describedBy@wt.part.WTPartDescribeLink~describes^wt.part.WTPart~ARTICLE_DESCRIPTION_DE@com.test_fuchs.article
describedBy@wt.part.WTPartDescribeLink~describes^wt.part.WTPart~ARTICLE_DESCRIPTION_DE
What am I doing wrong? 
Thanks in advance!
