​
Create the GetCases activity

1

Create the variables

On the Parameters tab, create three variables:
  • result of type String
  • currentCaseId of type String
  • tempResult of type String
2

Get the list of available cases

Call Call pzGetCasesByFilter and select the Pass current parameter page option.pzGetCasesByFilter writes all the cases to myStepPage.
3

Loop over the returned cases

Create a step with a Property-Set method that returns cases from myStepPage in a loop.
  1. Add a loop and select For each element in value list.
  2. Specify the myStepPage.cases property.
  3. In the method parameters, set the Param.currentCaseID variable to myStepCase.cases(<CURRENT>).ID.
4

Get the details of each case

  1. Type Call GetCaseDetails on the Method tab.
  2. Type myStepPage.cases(<CURRENT>) in Step Page.
  3. Set the caseID parameter to Param.currentCaseID.
For the activity itself, see Create the GetCaseDetails activity.
5

Store the result as a string

Convert the result obtained in the previous step into a string and write it to the Param.tempResult variable.
6

Add the JSON separator

To generate a valid JSON string, add a comma to the Param.result parameter, which is Param.result + ",".In the When field, add the following two conditions:
  • If @IsParamBlank(tools,"result") is true, Skip Step. If the parameter is false, Continue Whens.
  • If @IsParamBlank(tools,"tempResult") is true, Skip Step. If the parameter is false, Continue Whens.
7

Append the case to the result

Check whether tempResult is empty. If it is not empty, add the value from tempResult to the main result, which is Param.result + Param.tempResult.
8

Build the final response

Create the final response "["+Param.result+"]" and write it to the Param.Response variable.
