I'm having some trouble with the WorkspaceRunner transformer in FME 2018 windows 32 bit.

Say Workspace B contains a FeatureReader transformer. In Workspace B, create a published parameter called FileList with a filename (Multiple) and set this as the dataset field in the FeatureReader to read txt files. Set the value of FileList to C:\\temp\\a.txt,C:\\temp\\b.txt. I have no errors running workspace B as is.

 

Using FME 2018, I trigger workspace B using a WorkspaceRunner in Workspace A, I get an error which highlights the paths in the Filename (Multiple) parameter are not valid. It is using the same value as FileList (C:\\temp\\a.txt,C:\\temp\\b.txt) that is used in workspace b published parameter.

It seams that the WorkspaceRunner doesn't send through the FileList value correctly in FME 2018. I have examined the log files and can see that in 2012, the Command line arguments are different. See below for differences (notice the qutation marks missing in 2018):

 

FME 2012 log file:`--FileList' `""C:\\temp\\a.txt" "C:\\temp\\b.txt""'

FME 2018 log file: `--FileList' `C:\\temp\\a.txt,C:\\temp\\b.txt'

---

I also tried the following with abnormal results.

Open the WorkspaceRunner in FME 2018. In the FileList field set C:\\temp\\a.txt,C:\\temp\\b.txt as the value. Highlight the value (ctr-a) and then copy and paste it straight back in to the field. It then turns into "C:\\temp\\a.txt,C:\\temp\\b.txt".

 

Is this a bug or am I missing something here?

 

If you're passing a filename list as a published parameter you have to set it in the workspace runner in this sort of format

 ""D:\Folder1\File1.gz" "D:\Folder2\File2.gz""

Thanks for your reply. 

If I directly copy:

""D:\Folder1\File1.gz" "D:\Folder2\File2.gz""

and paste it into the WorkspaceRunner value in FME 2018, it does not stay that value. it turns into:

"D:\Folder1\File1.gz""","""D:\Folder2\File2.gz"

Notice the new quotation marks. Do you get similar results?
