Hi,

 

I am a beginner, mostly have been using graphic QGIS interface before this. I appreciate FMN Workbench very much 🙂

 

I have been comparing old and new data from catchment area streams. Suddenly the second AreaOnAreaOverlayer stopped working. No matter what I did: it did not bring anything else to the table than the _overlaps data column. It's quite a big area (with smaller catchment areas in it) I am studying so the information about the catchmentarea_id is important. I'm choosing only the areas where are streams defined to me when I started working.

 

This is for someone having the same issue:

  • do not spend time with transformer not working. Copy the first one working and rename it for example 2_AreaOnAreaOverlayer. I didn't let the system to rename it anymore, just in case because I don't know why the table information disappeared.

 

Hope this helps someone other to save time.

Once thing which could have been happening is that the Attribute Accumulation mode was set to "Use Attributes From One Feature" (the default) or "Drop Incoming Attributes". If you want to get attributes from overlapping features then it needs to be set to "Merge Incoming Attributes"

Thank you for your answer, you are kind. This is true 🙂 I was going through everything and matching to the working one. It started to be confusing so I took "the easy road".
