I'm seeing this as well on Craft 2.6.2988 with SimpleMap version 1.8.2, with the SimpleMap field outside any Matrix field; simply the usual field on an entry.

Digging in, it looks like the $data value being provided from the SimpleMap_MapFieldType content is null when it's being saved, which is why it's throwing an error. I haven't looked into it enough to know exactly why that is. The field has content.

EDIT: Found the issue. The ContentModel fetches the column data for the entry—but Simple Map doesn't use that column; it has a separate table. So when that content is checked, it's null, which is throwing the error. PR is submitted here.

That's brilliant Taylor - thank you for looking into this. Hopefully your solution will be merged quickly.

@Tam I am experiencing this same problem on SimpleMap version 3.3.3 with Craft 3.0.1. Can you merge the fix into the v3 branch as well?

I’m still receiving the same error with SimpleMap 3.3.3 and Craft 3.0.2.

@AdamVig @jannisborgers I've just tested saving a map in a matrix and was unable to re-create this error. If this is still an issue, could you open a new issue and include the error message you are seeing?

@Tam Thanks for your reply. The plugin is now working for me.

It looks like a recent Craft update fixed it, because that is the only thing that has changed since I originally commented.
