As stefan already mentioned, we most certainly can.

Personally I'm curious whether the OP's "toInteger()" call that was added in the second code snippet somehow made a difference (usually for a hard-typecast parameter, though, i'd expect it to be handled gracefully, but who knows whether this is some weird corner case).

Thanks Stefan Helzle
Jose Castellot - Can you please post here what was the issue if you were able to find that?

You can use a!startProcessLink with any link parameter anywhere. I think the root cause was something different.

I see earlier you were using rich text and you're calling a!startprocesslink in link parameter, which was erroring.

In order to solve issue, you used button and in save into you called a!startprocess.

Hi All,

For those who have the same issue, here you go how I fixed it:

a!gridColumn(
label: "BUC",
value: a!buttonArrayLayout(
buttons: {
a!buttonWidget(
label: fv!row.IDE_CLIENTE,
style: "LINK",
size: "SMALL",
color: "NEGATIVE",
saveInto: a!startProcess(
processModel: cons!ABS_CLIENT_REQUEST2_PM,
processParameters: {
buc: tostring(fv!row.IDE_CLIENTE)
}
)
)
}
)

Thanks and regards,

Jose Castellot

Hi Harsha,

Yes when the BUC link is clicked we are calling a process triggered in the backed, but we are using a!startProcessLink inside the a!gridColumn and is when we are getting the error: A null value has been passed

if we run the process for debugging it is working fine, so the issue is at the moment to invoke the process from the interface. For any reason the value is not being passed.

Hi Stefan / All,
Thanks for your soon response, originally the buc search page of the Site's navigation menu was configured as a process, so the form was part of the process, however it was decided to change the configuration of the page as an Interface, to avoid creating new threads every time the user clicks on the buc search page.

The BUC is entered by the user in the form and that value is passed to the process model, on the other hand the table where the buc value is stored doesn't have a record type, we are using a DSE.

The situation is that the client wants to navigate between the different pages of the Site once the buc value is selected in the buc search page. So we created a table to store the buc value associated with the session of the user. Before that change it was working as expected, I think the issue is the way we are calling the process.

No, but for my connecting the process to the right record typically does the trick.

When you click on the link is there any process instance triggered in the backend?
When you test the process by passing a value in the process model (using start process for debugging) is it working properly?

Hi Stefan Helzle ,
Can we pass multiple parameters into the process model if we are triggering it via Record Actions or related actions instead of using startProcessLink() function?

RE: How to call a!StartProcessLink() inside a!gridColumn

Stefan Helzle — Sun, 24 Aug 2025 12:36:04 GMT

Do you pass the value into the start form of that process?

Did you consider to use a record action?
