I created a Custom transformer that contains a FeatureReader set as Esri ArcGIS Server Feature Service.
I want to set Spatial Filter via an attribute. For this I created a conditional attribute (DE-9IM) with values TT*TT**** for Intersects and ********* for <No Spatial Filter>. If the case is that there is no filter, a conditional WHERE CLAUSE activates.
The problem is if the case is that there is no spatial filter the FeatureReader returns no data.
What is the corect DE-9IM value for <No Spatial Filter>?
