Maximum Number of Categories in Category Combination?

Hello All,
We are currently running version 2.33.1, Build revision: 7ab6211, Build date: 2019-11-27 12:55

Please is there a maximum number of categories that can be combined in a category combination?

I have a complex dataset that has up to six different categories and I am trying to combine them in a category combination and it keeps giving me an error (which for some reason does not really display but shows an orange ‘ok’) but in the console, I get a 504 Gateway Timeout.

I also noticed that it still goes ahead to save but when used with a data element and added to a dataset, the form does not load (section form), the custom form designer does not load, and when I try to delete the combination, I get a 504 as well and it does not delete.


Updating category option combinations in the maintenance app under data administration gives a 504 as well:

Could someone please help us take a look at this issue?

Thank you so much

I’m not able to - if there’s some hidden limit in the system, it’s not documented as far as I know.

But then I reported another bug during the weekend related to a feature (data element “Field Mask”) that according the manual is supported by Tracker and Capture, but which turned out to NOT be supported.

so somebody from the core dev team with a good understanding of the code need to clarify if there is some unknown “hard” limit here.



Thanks @Calle_Hedberg

Let’s hope for someone who can throw more light
