Dynamic Types Valuepicker not behaving as expected

[Karlzzon]

Vro Version : 8.18.0

To try and avoid the XY problem, let me start by describing where this problem stems from. Im trying to design a service library item, where the input is supposed to be a dynamic object representation of a VM. The problem i ran into was that despite my findAll wf finding 28 objects, only 20 ("showing 20 of 20 results") were displayed in the valuePicker.

To try and figure this out, i made the following test:
test3.wf.ts:

import { Workflow } from 'vrotsc-annotations';
@Workflow({
 name: 'MyTestWorkflow3',
 path: 'Redacted/MyTests',
 input: {
   testInput: {
     type: 'DynamicTypes:VCD.MyTestType'
   }
 }
})
export class wf {
 public wf(testInput: string): void {}
}
 

test3.wf.form.json:

{
 "layout": {
   "pages": [
     {
       "id": "page_1",
       "sections": [
         {
           "id": "section_0",
           "fields": [
             {
               "id": "testInput",
               "display": "valuePicker",
               "signpostPosition": "right-middle",
               "state": {
                 "visible": true,
                 "read-only": false
               }
             }
           ]
         }
       ],
       "title": "General"
     }
   ]
 },
 "schema": {
   "testInput": {
     "type": {
       "dataType": "reference",
       "referenceType": "DynamicTypes:VCD.MyTestType"
     },
     "label": "Test",
     "default": "",
     "constraints": {
       "required": true
     },
     "valueList": {
       "type": "scriptAction",
       "id": "com.redacted.vcd.someproject.actions.tests/findall",
       "parameters": []
     }
   }
 },
 "options": {
   "externalValidations": []
 },
 "itemId": ""
}
 

com.redacted.vcd.someproject.actions.tests/findall:

/**
* @returns {Array/DynamicTypesDynamicObject}
*/
(function main(): DynamicTypesDynamicObject[] {
 const resultObjs: DynamicTypesDynamicObject[] = [];
 for (let i = 0; i < 45; i++) {
   const temp = DynamicTypesManager.makeObject(
     'VCD',
     'MyTestType',
     `${i}`,
     `MyType ${i}`,
     []
   );
   resultObjs.push(temp);
 }
 return resultObjs;
});
 

This seemed to have some effect, since the input field now recognizes that there are 45 available values, not only 20. However, the objects are not displayed properly in the valuePicker. See image below.

Am i missing anything in my form ?

To be honest, I haven't tried this with dynamic types specifically. I can suggest 2 things:

1. At the end of your presentation action add a log to validate whether all the data is actually returned - sometimes when you test the action in isolation could give different results then when calling it from a form since there is different metadata available. For this purpose you could log via `Server.error("", "Your log here where you stringify the collected data"). Please note that the actual log message is the 2nd parameter, not the first in this specific case. Then you can find the logs in the Orchestrator -> Administration -> Audit logs - they will show there as soon as the UI action is triggered even if the Workflow is not actually called. I prefer to use error severity when debugging just to make sure it is easier for me to find.
2. If it gives you too much trouble you could actually use a simpler type for the UI and then instantiate the actual Dynamic Type object in the Workflow itself. If you need all the data from the object you can use a table and add 1 column for each attribute of the object, then in the presentation action itself you could simply return an array of plain JSON objects like:
   {
   name: dt.name,
   id: dt.id,
   state: dt.state
   ....
   }
   And if you want a simple dropdown with just VM names you can actually return and object with label and value, the label will be populated in the ui and the value will be the actuall value sent to the workflow, e.g. the VM id:
   {
   label: dt.name
   value: dt.id
   }
