Hi Leonardo,
In "Start a subworkflow" action you can only map attribute, not Item list.
A nice workaround it's just put another action - "Update item list values" and map entire list to your new form in your path, that's you use to create subworkflow.

Have a nice day!

Hi everyone,

I'm facing an issue while trying to map an Item List using the native "Start a subworkflow" action.

My Scenario:

I have a single Application containing two workflows: "Pedido de Orçamento" (Purchase Quotation) and "Pedido de Compra" (Purchase Order).

Both workflows share an identical Item List structural layout (same column names like Artigo, Quantidade, etc.).

I want to move the process from "Pedido de Orçamento" back to the Author so they can choose a path named "Realizar Pedido de Compra". This path should trigger the action to create a new instance in the "Pedido de Compra" workflow and copy the Item List rows.

The Problem:
When I go to the "Data" tab inside the Start a subworkflow configuration screen to map the fields, the target Item List from the Purchase Order workflow does not appear at all in the left panel. Only a generic single-line field (Detalhes do Pedido) is visible.

What I have already verified:

Both workflows are definitely inside the same Application.

In the target workflow ("Pedido de Compra"), the Item List visibility matrix is completely opened and set to "Visible" right at the initial/registration step.

I have tried changing the Form Type in the action configuration to match the target form, and I also tried leaving the Path configuration completely blank to target the registration step matrix, but the list still won't show up for mapping.

I tried switching to Advanced Edit Mode, but the source form fields tree on the right doesn't load the structural parameters either.

Has anyone encountered this specific behavior where an Item List is ignored by the subworkflow wizard within the same app? Are there any hidden caching issues or specific form configuration dependencies I might be missing?

Any help or workarounds (besides moving to raw SQL actions) would be highly appreciated!

Thanks in advance,
Leonardo

In new 2026.2 version, we can choose model for various AI function but not for prompt function.
Is prompt still using Gemini 2.0 lite?
it's giving us bad results with simple tasks, and I'm wondering if it can be changed to 2.5 like for concierge or do we than have to get AI proxy and our models for all?

We have an action which uses Generate/Update Word to generate an offer.
We have an item-list, and all colums have a local label like "Betrag" and a translation label for uk-UA "Amount"

This is working fine. Default (application settings) is producing the german version, uk-UA is producing the englisch version of the item-list.

We need now also a data-table. Same idea: local labels (german) and uk-UA labels. However the automatic translation does not work for the data-table.

Any ideas?

Hi,
The problem most likely stems from the fact that the call doesn't return a Content-Length header. In this case, the system can't determine the file size, resulting in the error message.
You can confirm this in Postman

Hi Ernst,

I would start with inspecting the request WEBCON executes and compare it to the one postman submits. I use HttpToolkit in these cases.

Regardless, if you already have an option to get the content, you could use the add attachment action to generate to binary data for the attachment.
When attachments are to be created when executing the action, the query must return columns FileName and Content, containing the attachment’s name and byte content. The query may also return a Description column if required.
https://docs.webcon.com/docs/2026R1/Studio/Action/Attachments/Action_AddAttachment
SELECT convert(image,'0x') AS Content, 'file1.txt' AS FileName

Best regards,
Daniel

The Express (Freemium) version is no longer available. If you need to test the WEBCON platform, please use the TRIAL version (online: https://webcon.com/trial/ ) or the 90-day DEMO version (to be installed on your own environment).

Hi,
I have simple Invoke Rest Action, which should download a file (pdf).

I get this error:

Validation error: Invoke REST Web service - Request Url:
https://myhost.com/v1/dms-archive/v1/Kundenakt/documents/4711-abcd-1234/contents/0
Response Code:
Exceptions:
Total size must be greater than zero

* Same call in Postman downloads the file correct
* If I change the content type in the action from "binary" to json, I get correct response-code 200 and the binary as text in a multiline-field

Other REST-downloads (other endpoints) are working as expected.

Any ideas?

Hi,

I'm not aware of any public link, you will probably get a link using the official page.
https://webcon.com/demo/

Keep in mind that the new Freemium versions are now limited to a 90 day usage. I have in mind that this was introduced with the release of WEBCON 2026.

Best regards,
Daniel

Hi everyone,

Is WEBCON BPS Express still available for download?

I found some older information mentioning https://starter.webcon.com/, but this address does not seem to work anymore.

Is there currently any official download link or activation path for WEBCON Express?

Thanks in advance for any help!
