tMap with 2 tSalesforceInput Components: "Failed to Generate Code" Err

jdope — Sun, 29 May 2016 22:10:49 GMT

Hello...
I've been banging my head against the wall for two days on this. I had a very nice flow working, closed my job and when I open it again I get a "Failed to Generate Code" error.
I've spent some time and got it to the most basic elements for trouleshooting:
--Input from an .xlsx file to a tMap out to an .xlsx file.
--Two tSalesforceInput components provide lookup tables to the tMap input (see image below).
If I setup the components and flow, close my job, and open it back up, click on the "Code" tab no code is generated and the below exceptions are being logged.

If I delete the link from the tSalesforceInputs to the tMap, close my job, open it, code is now generated. So it seems there is something awry with the tSalesforceInputs. What am I doing wrong? Why did this work fine, then break after I closed my job and reopened it??

Something I've noticed:
Drag the connector from tSalesforceInput to tMap. Save. Note the connector name "row2(Lookup, Main)". At this point I can click on the code tab and code is generated. I can open the tMap to see the settings.
Before

Close the job, then reopen the job:
Note that there is now a Warning: "This component has too much "Row" type inputs." message on the tSalesforceInput. The connector name has changed to "row2(Lookup)" and I am unable to generate code. I am also unable to access the tMap settings. (Unhandled event loop exception) .

If still possible can you share the job that causes the error?
