Passing a button value as PV to a Process

Hi Adi,

Are you smart service (start process), if so, please check that PV is set to parameter inside process model and you are passing it correctly.

Thanks,
Nafis Khan

Hi Nafisk001,
Here is the code snippet from my interface. I am not using any smart service. I am using the bind, get, set to start the process from the interface.


local!export: bind(
get{local!ClaimID, local!ClaimantID, local!buttonValued},
startprocesswrite(cons!ClaimReport_Process_ID, _)

a!submitLink(
value:{
local!ClaimID: local!ClaimId,
local!ClaimantID: local!ClaimantID,
local!buttonValue:local!buttonValue
},
saveInto: local!export
)

saveInto: local!export
)

I will have to get that a try.. But in mean time, see if it is any help to you.

Incase if you are using two linkfields one for "Download" and One for "Email", Try using the below code:

{
  a!linkField(
    label: "Send as Email",
    links: a!submitLink(
      value: {
        local!ClaimID: local!ClaimId,
        local!ClaimantID: local!ClaimantID,
        local!buttonValue: "Send as Email" /*Recommended to use the constant*/
      },
      saveInto: local!export
    )
  ),
  a!linkField(
    label: "Download",
    links: a!submitLink(
      value: {
        local!ClaimID: local!ClaimId,
        local!ClaimantID: local!ClaimantID,
        local!buttonValue: "Download" /*Recommended to use the constant*/
      },
      saveInto: local!export
    )
  )
}

Hi Vimalkumars,
I have been using like the one you shared. Unfortunately, neither of the values are accessible in the Process or I have no idea how to access this buttonValue inside the process instance.

Thanks,
Adi

Hi AdirajuB,

Have you tried testing it by hardcoding the values as below
value: {
local!ClaimID: local!ClaimId,
local!ClaimantID: local!ClaimantID,
local!buttonValue: "Download" /*Recommended to use the constant*/
},

Hi Vimalkumars,
yes, I have tried to do the hard coded value. But the problem is I am not sure how to access this in the process as all the values are coming as empty.

Thanks,
Adi

Can you please try the below code and see if this returining you the required outcome?

a!linkField(
links: a!dynamicLink(
label: "Download",
saveInto: a!startProcess(
processModel: cons!YOUR_PROCESS_MODEL,
processParameters: {
parameterNameClaimID: local!ClaimId,
parameterNameClaimantID: local!ClaimantID,
parameterNameButtonValue: "Download"
}
)
)
)

Hi AdirajuB,

I have updated the code for startprocesswrite as below. Please see whether this helps you.

load(
  local!export: bind(
    null(),
    startprocesswrite(
      cons!ClaimReport_Process_ID,
      _
    )
  ),
  a!linkField(
    links: a!submitLink(
      label: "Download",
      saveInto: a!save(
        local!export,
        {
          parameterNameClaimID: local!ClaimId,
          parameterNameClaimantID: local!ClaimantID,
          parameterNameButtonValue: "Download"/*Recommended to use the constant*/  
        }
      )
    )
  )
)

Hi Vimalkumars,

Thank you very much for your inputs. I have tried them all, and all of them work in the sense, I am able to invoke the process. But the process variables I defined are always showing null. Is there something I am doing wrong in defining the process variables or is there some error in the way I am accessing them?

I have even defined my interface as the start form in the Start activity and because there are no ri variables, it doesn't show any input fields. 

Do I have to define any specific variable in Process for me to be able to access the saved values from the interface?

 

Thanks,

Adi

Hi Nafisk001,
I have tried the method mentioned in the link. It still doesn't help as the variables are coming as empty. I have attached the screenshot below in the replies.

Thanks,
Adi

Hi Adi,

If you are using UI as start form for process model, then you can have ri variable.

What I have done.

1) In UI,defined ri varible ri!button. Below is the code.

load(
  local!export: bind(
    null(),
    startprocesswrite(80115,
      _
    )
  ),
  a!linkField(
    links: a!submitLink(
      label: "Download",
      value: "Download",
      saveInto: {
        a!save(ri!button,"Download")
      }
    )
  )
)

2) In Process Model, created PV as paramater (buttonValue)

3) Under Process Start form, mapped PV (under value drop down) to an interface ri variable.

The same is working fine for me. I have tried to attached the screenshots.
