Re: All folders hidden in Apppackage/AppFolder...
Jorg, if by 'hide', you mean make them invisible (as in adding a '.' to the file & folder names) well... then you are changing the names of the various files and folders that 4D is expecting to be in place... so that will not work. If you mean using 4D, or other means, to set the invisible bit without changing the name(s) that should not create any problem for your database. NOTE: I have never done this with 4D required files and folders, however I do create and maintain invisible files and folders for internal use - and there is no problem. Can I ask..? Why?

Re: XML Null reference with DOM Find XML element
Hi Piotr, I have a small method DOM_validRef which basically uses this test: if(Replace string($ref;"0";"")="") $valid:=false end if 64bit indeed uses 32 zero chars instad of 16, but this code handles both situations (and future ones, if we live long enough to make the transiton to 128bit systems...). My method also checks if all chars in the XML ref are valid hex chars (0-9 A-F), but that might be overkill.

Re: XML Null reference with DOM Find XML element
Piotr, Hi. That seems like the expected behaviour according to the docs: https://doc.4d.com/4Dv17/4D/17.3/Overview-of-XML-DOM-Commands.300-4620648.en.html "Error Handling Many functions in this theme return an XML element reference. If an error occurs during function execution (for example, if the root element reference is not valid), the OK variable is set to 0 and an error is generated. In addition, the reference returned in this case is a sequence of zero "0" characters (16 characters in 32 bits, and 32 characters in 64 bits)." Does that help? Are you testing for OK = 0 in your code?

XML Null reference with DOM Find XML element
