Hi, I am trying to save the values of an activity class parameter in a variable inside a node.
In the expression of custom output AC!Variables.restaurant works and passes values correctly to the target process variable. However when I try the same with index(ac!Variables,"restaurant",null) it does not work and passes null values to the target process variable which subsequently errors out down the line.
I have tried several times but 'dot' works and 'index' does not.
Of course not a big deal but I would prefer using index than dot. Anything I am doing wrong? or shall I raise this with Appian Academy?
thanks

It's hard to tell from what you've provided what structure you're expecting to be returned in ac!Variables. Without insight into this we cannot advise as to how to address the 'restaurant' attribute in the structure.
sorry..
After I run the BOT, AC!Variables has this
{restaurant=[restaurantID=1, restaurantName=True Food Kitchen, restaurantStatus=Status: Permitted, inspectionDate=6/19/2396], healthDepartmentWebsite=https://inspections.myhealthdepartment.com/va-arlington}
If this helps - This is from the RPA tutorial.
What data type is your target 'restaurantList' ? Are you able to share the datatype?
The difference here when you use dot notation if your process variable is not an array type I think it is taking the value and casting appropriate type. When you use the index it returns list of values, because of this it may ignoring the values (It shouldn't ignore return value, if that is happening it is an issue with Appian). Also as Stewart mentioned what is your process variable type.
Hi Stewart,
CDT is
Some more experiments I did..
I saved the AC!Variables into another pv botVariables of type 'Map'
Now in another node in a script task I am doing this - Index on botVariables and this works perfectly fine
this time restaurantList is populated with values ..
Now I have 2 questions
1) why index() on botVariables works when I am storing ac!Variables into botVariables but why index() directly on ac!Variables not working.
2) why 'dot' works and not index() on ac!Variables
I sincerely hope i can go on a video call with you ..anyway let me know if you see any issue here.
Again, I have a work around so this is not blocking.
regards
hi Naresh, i am new to Appian so really don't know what might be happening but I have just responded to Stewart with more details and another scenario how I made index() stuff work by storing the ac!Variables into another pv botVariables. pls have a look
thx
