Hello,

 

I have created a list of one specific attribute (Listbuilder), which I have finally cleaned from duplicate entries (ListDuplicateRemover). So the list contains several elements, but they cannot be duplicated. As a next step I want to select all geomtria from another dataset which are contained in the list. When trying to do this with the FeatureReader, it seems that I can only specify one element in the WhereClause query. How can I select all geometries contained in the list in one step? I would like to avoid the detour via the PythonCaller 8-). Thanks a lot.

Have you looked at the listconcatenator to create a string containing all list elements for your where query?

Or explode the list (ListExploder) so each feature can supply a different value to the FeatureReader where clause. Or am I missing something?
