Solved: File Handling: Binary Objects to File: How set the filenames


from the Labs I use the "File Handling" extension and its "Binary Objects to File" node that I find very usefull to extract binary data from a database and write this data to files. In the configuration of this node there is a possibility to name the files by a column (see attached screenshot) but there is no possibility to choose a column. I tried a string column with the column name and hoped that the node would choose this by default but it didn't worked.

Can you please help me?
