Hello Everyone,
I am facing an unusual issue in Constellation (Infinity v25.1.3) and wanted to check if anyone else has encountered something similar.
Background
We have a data type that acts as a centralized repository for various application values used across dropdowns, radio buttons, and other selection controls. The data type contains fields such as:
- Category
- Key
- Value
- Supporting Text
All records are stored in the Pega database.
This design originated from a traditional application and has been carried forward into Constellation after migration.
The primary keys for this data type are:
- Category
- Key
To support read operations on data type, we have configured a single-record lookup data page using the above primary keys as well.
Use Case
We have a Delivery Type field that should allow users to select one of the following options:
| Display Value | Supporting Text | Key |
|---|---|---|
| Standard | 4-10 business days | STD |
| Fast | 2-5 business days | FST |
| Next Day | 1 business day | ND |
The requirement is to display these options as cards, where:
- The display value appears at the top
- The supporting text appears underneath
- The user can select only one option
Below is a mock up of how the setup should like (of course the radio buttons on the right side though),
Implementation
To achieve this, we created a single-select data reference property and sourced it from a list data page, passing the category Delivery Type.
The cards are rendered correctly and all three options are displayed as expected.
Issue Observed
When a user selects any one of the cards, all cards become selected simultaneously.
Initially, this seemed like a configuration issue, but after verifying the setup multiple times, no errors or misconfigurations were found.
To isolate the problem, I tested the same data reference property using different presentation types.
Results
Not Working
-
Cards
- Selecting one option selects all options.
-
Dropdown
- The list loads correctly, but no option gets selected.
Working Correctly
-
Autocomplete
- Selection works as expected.
-
Table
- Selection works as expected.
-
Simple Table
- Selection works as expected.
-
Search and Select
- Not explicitly tested, but I expect it to work since it is table-based.
For the working display types (Autocomplete, Table, Simple Table), after saving the case, the clipboard correctly contains the page corresponding to the selected record.
Conclusion
Based on the testing:
- The data type configuration appears to be correct.
- The data pages are resolving properly.
- The data reference property is storing the selected record correctly.
- The issue seems to be specific to the Cards and Dropdown presentation types in Constellation.
At this point, I am hesitant to conclude that this is a product defect, but the behaviour appears inconsistent given that other display types work correctly with the same configuration.
Has anyone faced a similar issue with:
- Single-select data references
- Data pages backed by data types with composite keys
- Cards or Dropdown presentation types in Constellation
Any insights, workarounds, or confirmation would be greatly appreciated.
Thanks in advance!
Regards
JC
