As an FYI I didn't put a null map in a list, it's just some values in some maps in the list are null while others aren't. | |

I don't know why you would put a null map in a list...you haven't shown us how you build that list so it's impossible to answer.

| Jun 16, 2017 at 22:25 | comment | added | Kamil Mieczakowski | Could it be the fact that I am getting the relevant string from a list of maps? that's what it is: String investmentsRow = allRows[i].get('Names'); It works when I debug it... | |
| Jun 16, 2017 at 22:23 | comment | added | Adrian Larson♦ | @KamilMieczakowski Then you are getting the error on a different line. Double check your stack trace. | |
| Jun 16, 2017 at 22:22 | comment | added | Kamil Mieczakowski | yes, I also pasted it in the above comment for your evaluation | |

@KamilMieczakowski Did you replace if (namesRow.contains('Andrew')) entirely?

I am still getting the same error when using your if class, for your reference, that's how it looks: if (namesRow != null && namesRow.contains('Andrew')){ system.debug('this name is in the list!'); }
