Subprocess as a nested process

[sagar....@flowian.com]

Hi Team,

Can we use subprocess as a nested process in parallel loop activity in my process.

In one my application I maintain history of application, But if my subprocess is not a nested one then the history of subprocess is missing from process history.

But if I do check the Nested process checkbox, then there is problem with the loop variable.

For each loop iteration the value of my loop variable remains the same.

Is there any other way to solve this problem ?

Regards,
Sagar

Hi,

A nested process is a sub-process that shares its variables with its father process. So,when a variable is modified in sub-process, it is instantly modified in father process since it is the same variable. That's why for each loop iteration value is getting overridden.

How you are maintaining history of application using History widget or some other mechanism ?

Thanks,

Sweta

Hi Sweta,

How can we add OR display the details of the history of that subprocess.

There is one method get_history(), which can be computed in subprocess.

But the problem is, If my subprocess is executed more than one time, then that computed variable shows me the history of only last subprocess.


I also try to store the history of each subprocess in one array which is defined in parent process using the following.

his_array= hisarray + curr_process_history

Assuming that at each array index there will be history of each sub process.

But still it wont work.

Regasrds,

Hi Sagar,

Try executing below code- 

1) In parent process initialize an array as -

   <@script env="javascript">

   var result = new Array();

   setVariable("result",result);

   </@script>

2) In output variable of activity containing sub process append this array with values/history retrieved from sub process -

<@script env="javascript">

var arr = new Array();

arr = JSON.parse(result);

var mainJSON = {};

mainJSON=history;

arr.push(mainJSON); 

setVariable("result",arr);

</@script>

where history is variable retrieving information from ${get_history()}

Hope this helps you.

Thanks,

Sweta

Hi Sweta,

Now my history var contalins history of all the subprocess instances.

Your solution is working.. Thanks.
