When running a workspace using a WorkspaceRunner transformer in FME some non-standard query string parameters in the WFS url are discarded and/or seemingly randomly replaced by equals signs.
Setup is like this:
Workspace "control": creator -> workspace runner (this runs the workspace "wfsread", parameter WFS URL reads https://[serverpath]?SERVICE=WFS&REQUEST=GetCapabilities&NodeId=287 Workspace "wfsread": wfs reader -> shapefile writer reader URL is "https://[serverpath]?SERVICE=WFS&REQUEST=GetCapabilities&NodeId=287"
Now, when running the control workspace, the log of workspace "wfsread" starts with
2019-01-15 10:12:42| 0.0| 0.0|INFORM|FME Configuration: Command line arguments are 'C:\FME\fme.exe' 'D:/wfsread.fmw' '--SourceDataset_WFS' 'https://[serverpath]?SERVICE=WFS=GetCapabilities=287' '--FEATURE_TYPES' 'L525 L50 L48 L383 L382 L381 L377 L34' '--DestDataset_ESRISHAPE' 'D:\'
...so FME is somehow throwing away the characters "NodeId" and replacing ampersands with equal signs in the call to the wfsread workspace.
Is this a known issue, and/or are there workarounds/settings that can mitigate this?
