Property Transfer Definition Source Expression with relative path
how can I refer to another object on the same level of the control structure tree? I tried the path as in the attached screenshot, but it tells me “invalid”. I also tried the path $’../ResultsSum:Value’, for which verification is ok. However, when activating the property transfer, I only receive the substitution value and not the source value in the target property, so it also doesn’t seem to work. I would be glad if you could help me out. Thanks!”
Make sure you have the Property Transfer Service enabled.
Also check that Target Property aspect is declared on the destination object and is of the same (data) type.
Target Aspect should read "Control Connection" or "Name" depending on where data is supposed to be coming from, Target Property defines where to put it.
Source Expression is where your data will be coming from. (Use copy/paste and Verify)
B t w, Property Transfer shall be used with causion, make sure to set the timing accurate, there is a chance/risk of overload/poor performance.
A: by using a Property Translation
Avoid transfers as they result in a write. If your task is to refer, you better use a translation.
There is also a new feature called Property Server service. Will try to post an example in a few days time.
Remember that "/" is by default expanded to /*/, i.e. you do not need to specify the complete "downpath" route. This may or may not cause trouble if names are not unique. The above expression can be abbreviated to $'[Up][Up][Direct]/GC1:General Properties:VALUE', i.e. omitting "C1". This will work as long as the expression is unique and only matches one (1) object named "GC1". In doubt, try searching for "GC1" with the Find Tool, with more than one (>1) hit you may have to give full path to avoid ambiguity.
With an increasing number of uncached subscriptions, display exchange performance will take a hit.
If possible, avoid property translations if the expression syntax can be built into the PG2 display itself - built-in expressions will be cached.
