I have a UDT, inside it there is root R and inside it there are memory tags.
one of the memory tags has a value {document}. Inside {document} there is object which has another object that has some values that I want to access with expression:
[~]my folder/R/mytag → Value → 2nd object → first parameter
Does this help at all?
EDIT: I see now you’re looking for an expression solution, so that might not be exactly what you’re looking for, but it might help get you there…
It helped a lot! Thank you!
Hi, I have a somewhat related issue. This one helps, but what if the “bar” in your example is a number? How do I access the value?
Keys that start with a digit are not permitted in JSON, and therefore not permitted in document tags nor in Perspective. (Though not strictly enforced.) Just don't have such keys.
Since the property editor isn't visibly yelling at you, it's likely that your key is actually a string-containing-digits, which you would access using the same subscript/square bracket syntax Kevin posted above.
But if it isn't, and also because it's just a confusing idea with poor support in general - as Phil said, don't use numbers as keys. If you need positional referencing...use an array, not an object.
Thank you! This helps. I will stop pursuing using digit as keys!
Yeah, digits does not work at all. Values are blank, but when I tried changing to a string then it gives me the values.
