How do you make a column in a gridField link to a specific record when the recor

I ran into this issue as well when linking to an expression-backed record in feed posts as well, the resolution was to wrap the record identifier in tostring() - that might work for your case as well. The solution to my use case was essentially:

=a!toRecordIdentifier(cons!RECORD_CONSTANT,tostring(pv!CDT_var_here.uniqueId))

Unfortunately, it's not serving me any justice within my gridTextColumn. It doesn't like how I'm trying to go to text values from a datasubset.

Posting your code here may help. Also, I realized I do this in a report as well - this is my gridTextColumn (service backed record). In this example, fldID is the unique identifier and fldSIRnumber is displayed to the user as the record link text. local!gridData comes directly from a queryEntity() call:

a!gridTextColumn(
label: "Request #",
data: local!gridData.data.fldSIRnumber,
links:
a!applyComponents(a!recordLink(recordType: cons!SIR_RECORD,label: _, identifier: _),
merge(
index(local!gridData.data,"fldSIRnumber",null),
index(local!gridData.data,"fldID",null)
)
),
field: "fldSIRnumber",
alignment: "CENTER"
)

I just implemented your code and it works!

Just for feedback, I tried to implement something similar before I broke and asked the community, but it seems like the applyComponents function made a big difference.

Great! a!applyComponents() is very helpful for dynamically adding SAIL components.
