Modern UI conversion of IN304000 (Transfers) generates invalid TypeScript — publish fails on 2026 R1

Hello, currently I’m using Acumatica 2026 R1. I’m running into an issue after Convert to Modern UI for screen IN304000. Steps to reproduce : 

1. Open screen IN304000
2. Convert to Modern UI (generates IN304000.html, IN304000.ts and views.ts)
3. Opens a project in Customizations Project
4. Add Modern UI Files → Select IN304000.html, IN304000.ts and views.ts
5. Publish project

After publish, I encounter error log like this : 

[2026-08-14 06:41:23.069] npm run build failed with output:

Error output:



Publishing customization FAILED

After I check the generated files, I notice some issues : 

Issue 1 - unescaped double quotes inside a string literal

IN304000.ts, line 14:

@viewInfo({containerName: "Details", parameters: [new ControlParameter("INTran.docType", "transfer", "NewDataKey["DocType"]")]})

The inner double quotes are not escaped, so the parser reads five arguments instead of three:

- "INTran.docType" - arg 1
- "transfer" - arg 2
- "NewDataKey[" - arg 3 (string terminates here)
- DocType - arg 4 (bare identifier)
- "]" - arg 5

This accounts for the two TS1005 errors, the TS2304, and the TS2554.

Issue 2 - empty parameter value

views.ts, line 148:

@controlConfig({parameters:(screen: IN304000) => ({ "INTran.docType": ,})})

No value is emitted for the parameter.

Issue 3 - parameters reference fields absent from the generated type

views.ts, lines 66, 95, 192:

line 66 : 

parameters: (screen: IN304000) => ({ "INTran.siteID": screen.transactions.activeRow.SiteID.value, ... })

line 95 : 

parameters: (screen: IN304000) => ({ "INTran.toSiteID": screen.transactions.activeRow.SiteID.value, ... })

line 192 : 

parameters: (screen: IN304000) => ({ "INTranSplit.siteID": screen.splits.activeRow.SiteID.value, ... })

SiteID exists on both INTran and INTranSplit at the DAC level, but it is not exposed as a control on the Transfers screen (the source warehouse is set in the header). It therefore does not appear in the generated type, while the selector parameters still reference it.

Questions : 

1. Is this a known issue for 2026 R1?
2. Is there a supported workaround, or is removing IN304000 from the conversion the only option for now?
