OK, so my changes over in #6983 cause this to be a fatal error. Here's the progression:

• Before #6983
  • The simulation fails without an error. This is because an exception is thrown when the input processor is trying to preprocess some specific IDF objects to build out the output variable requests. This includes the Output:Table:* objects
• After #6983
  • The simulation fails with a nice fatal error saying that the problem is a blank report name in one of the associated objects here...an improvement...but not ideal
• Proper fix
  • If we want to make the report names required, then we need to change that in the IDD, and then the input processor will validate it.
  • If we want to allow it to be blank, then the try blocks added in #6983 should be converted to actual checks on the JSON keys, and handle that situation appropriately.
  • In addition, an audit should be performed for all the output objects processed in JSON to make sure we handle blanks appropriately
  • In addition, we should verify that by "skipping" the field, we don't miss out on some other initialization

[Myoldmopar]

I'm changing this milestone to E+ next and moving on.

@Myoldmopar Seems like we should just make it required in IDD. It's a simple IDD change, and the user will know where to go look, no?

[mjwitte]

For Output:Table:SummaryReports, the behavior has been. v8.7, v8.8: ** Severe ** Output:Table:SummaryReports Field[2]="", invalid report name -- will not be reported. Simulation continues to completion. v8.9: unexplained fatal error. v9.0: ** Fatal ** Blank report name in Oputput:Table:SummaryReports. This should have included a transition rule to clean out any blanks so that working files from v8.8 and before would transition successfully. Now these will fail if there are any lurking out there with a blank report field.

Of course we also have a bunch of other old key choice synonyms out there that were never added to transition, so add this to #6601

[mjwitte]

Just retested this, behavior is still the same as noted here. Forgot to deal with the blank field case in #6601, so will make a new pull request to address this in Transition-V8-8-0-to-V8-9-0.

Just FYI this seems to still be an issue in 9.6, at least for the Output:Table:Annual. It's easy enough to fix in the text file, but the IDFeditor causes the fatal error. There is also a typo in the error message where Output is spelled 'Oputput'

[mjwitte]

Reopening this issue. Seems we should be able to trap blank unrequired fields and not error out on them, maybe.

[JasonGlazer]

@mjwitte and @Myoldmopar I was thinking about taking on this issue. It seems like this issue started out just trying to make sure a blank report name in Output:Table:SummaryReport occurs. This would be a straightforward fix. But near the end of the conversation, it seems like maybe this is an issue in general about how blank unrequired fields should be treated. That seems very open-ended to try to fix since it probably matters for each field. So which is it?

[mjwitte]

This only applies to blank fields in a few objects that get pre-processed by the input processor. Other blank fields return blank or zero or their default.

@Myoldmopar 's changes in 6983 let blank fields get past the input processor for the pertinent report objects. So, if I'm following correctly, all that's left to do here is to change the fatals added in #6983 to warnings for Output:Table:Monthly, Output:Table:Annual, and Oputput:Table:SummaryReports.

[JasonGlazer]

That is great that it is only those couple of input objects. Thanks @mjwitte

[JasonGlazer]

Do you think they should be Severes or Warnings? I was leaning toward Warnings.

[mjwitte]

Warnings.
