How to show form using a!startProcess()

If you are using Appian 17.4 then you can use a!startProcessLink() to achieve this. Before version 17.4 I do not think there is a way to accomplish this.

Hey Josh,

Thanks for your reply. I already tried with a!startProcessLink() but my issue here is that I'm using multiple links and on the basis of users click I'm trying to fetch the value from the link.

for eg: Suppose I have one array variable lets say "uri" which consists of three links lets say

https://../../12
https://../../13
https://../../14

Now I'm fetching the values from these links to one another array variable lets say "Value". Such that Value contains 12,13,14. If user clicks on first link that I want 12 to sent as a parameter. Similarly for other two links, As a!startProcessLink doesn't have any way to save values I'm not able to pass the required value in process model. Either I can send all the values i.e. 12,13 and 14 to the process model or else only one value will get passed no matter which link I click.

Could you have a list of a!startProcessLinks and parametrize the process parameter? Ex. a!forEach(items: ri!uriList, expression: a!startProcessLink(processParameters: {value: rule!someRuleToParseValueFromLink(fv!item)}))

I think I already did that with apply function. Below is the code snipet

links: a!applyComponents(
function: a!startProcessLink(
label: _,
processModel:cons!WebJobLaunchConst,
processParameters:
{
KeyProcessStream_int:cast(3,local!KeyProcessStream_int)
}

),
array:index(local!datasubset.data, "TextBetweenTags", {})
)

Please let me know if im missing anything

FYI: "TextBetweenTags" consists all the links and "KeyProcessStream_int" consists all the value extracted from links.

Your implementation would pass in first value in local!KeyProcessStream_int for every iteration of a!startProcessLink(). The only thing that is changing for each instance is the label.

Try replacing it with the following snippet:

 

a!foreach(
    items: index(local!datasubset.data, "TextBetweenTags", {}),
    expression: a!startProcessLink(
        label: fv!item,
        processModel: cons!WebJobLaunchConst,
        processParameters: {
            KeyProcessStreamInt: cast(3, index(local!KeyProcessStream_int, fv!index, null))
        }
    )

)

Thank you so much Josh. Your code works fine for me. I was working on this from long time and finally you helped me to resolve this. I really appreciate your time and effort. Thanks once again

You made my day Josh. Thanks again :)
