I got this error when edit a page. 

Catchable fatal error: Argument 1 passed to WireData::setArray() must be an array, boolean given, called in /home/hdps/domains/ioaffiliato.com/public_html/wire/core/Data.php on line 37 and defined in /home/hdps/domains/ioaffiliato.com/public_html/wire/core/Data.php on line 68

Can you provide more info or steps to reproduce? When did it start happening, and what events preceded it happening? Does it happen on All pages, or just one or some?

I created a new template, i created two new fields for this template than i created a page with this template on second level, root->category->page. After this i get blank page, completely. Get back in the browser and clicked edit on this new page i can see in the tree view.

the url is:

Thanks for this info. I am not near a computer today (other than this cellphone), but will find and fix this error tomorrow. It appears that the error is happening in the core rather than due to a specific API call, so I'm assuming this is a bug, and should be easy to fix once I get back to the office.

By any chance do you have a field named 'data' in your list of custom fields?

[Frank Vèssia]

ops...yes.  ;D i have this bad habit sometimes to use italian words for fields...btw you should correct this.

Okay I think that's it then. 'data' is a field name used internally by ProcessWire. It should have given you an error about that, but it looks like I hadn't yet added this to the list of reserved words. I'm adding it to the list, so thanks for finding it!
