Document Generation API: Conditional test with null values

[bruceb92825582]

If my JSON contains null values (see sample below) how do I use that in a conditional test?

I've tried several combinations but none have the results I want - see attached Word document and sample PDF output. 

{
"FirstName": "Joe",
"LastName": "Bloggs",
"Address": "1 Acme Drive London SW15 2RQ United Kingdom",
"PolicyNumber": "1234456",
"Premium": "$344.50",
"PaymentMethod": "Credit Card ending 2345",
"PolicyStartDate": "2 April 2022",
"PolicyEndDate": "1 April 2023",
"Coverage": [
{
"TreatmentName": "Crown re-cement",
"TreatmentType": "Major",
"IntervalPeriod": 12,
"Quantity": 1,
"PerTooth": "Not Applicable",
"Coverage": 50,
"MaximumCover": null
},
{
"TreatmentName": "Dental Implant Treatment",
"TreatmentType": "Other",
"IntervalPeriod": 12,
"Quantity": null,
"PerTooth": "Not Applicable",
"Coverage": 100,
"MaximumCover": "$2,000.00"
}
]
}

On further testing it appears that the != (not equals) comparison operator does not work when inside a repeating section.

Hi there!

I solved this issue by using the following text, using "Sample_Variable" as the placeholder for what your variable would be.

{{`Sample_Variable`}}{% conditional-section expr(`Sample_Variable` = null) %}None{% end-section %}
