This page is for new to experienced workflow designers who are building a new workflow and looking for a pattern to meet their business requirements. These examples may help you to choose the best design pattern for your situation before you begin building it. Here is chart to help you compare some common patterns; many workflows combine multiple patterns.

Save to User - pass steps between arbitrary users
Tip |
---|
Watch this 3-minute video to see how we at frevvo are using the Save to User feature to allow multiple users to collaborate on a workflow step in a flexible, ad hoc manner. |
In some cases, you may want multiple actions taken during a step in the workflow but in an ad-hoc manner. For example, consider a workflow to review a proposal. The first step is the Proposal entry and the second step sends the Proposal for review. However, a number of users may review the proposal in any ad-hoc order.

- Build the Employee Review Workflow first. This is the workflow that is launched by the Employee Review Launch Form. Follow these steps:
- Create a new workflow and name it Employee Review workflow. If you want to know more about creating workflows refer to Workflow Tutorial.
- Drag and drop 4 text fields from the palette.
- Name them EmployeeID, ManagerID, FirstName, LastName respectively in the properties panel of each text control.
- You can add any additional fields you want but that is optional.
- Click Workflow to return to the Workflow Diagram. Click the first step to display it's properties.
In the Assignment tab enter {ManagerID} in the Assign to User field. Note |
---|
If assigning the first step to an email address template, you must set encode=false to prevent the "@" symbol from being encoded in your rule. The designer should use the template {EmailAddress!encode=false}. |
- Select Save & Exit from the menu at the top right.
- Copy the Share Dialog Raw Link URL for the Employee Review workflow (the workflow you want to launch for each employee) into that field. To do this:
- Go to the Forms and Workflows homepage.
- Click the Action Menu for the Employee Review Workflow and select Share.
- This will open a Share workflow wizard . Click on the Raw workflow link. Copy the URL in the left textarea. NOTE: any other share URL type will not work.
- Follow these steps to build the Employee Review Launch Form. This form will start multiple new Employee Review workflows.
- You cannot launch a workflow sent to the currently logged in user’s task list. You can only send it to another user’s task list. Make sure you are not logged into the other user’s frevvo account when running the Employee Review Launch form. This is being improved in a future release.
- Create a form named Employee Review Launch Form. To know more about creating form refer to Forms Tutorial.
- In the form drag and drop a text control from the palette.
- In the control’s properties on the left, name the control WorkflowToLaunchURL. You can enter any label you like.
- Uncheck the visible checkbox in the control’s properties to make the control hidden.
- Paste the copied URL in the Employee Review Launch Form WorkflowToLaunchURL field
- Make the following changes to the URL pasted in the field,
- Cloud customers must change http://app.frevvo.com//443/ to frevvo:// in the URL to the workflow.
- In-house customers must change the http:<domain>:<port> to frevvo:// in the URL to the workflow.
- Save the form.
Add an EmployeeID dropdown field. The HR manager will select the employees to be reviewed from this dropdown. You can either add the userId in the Options field in the properties panel of the dropdown control or fetch all the users from the tenant through business rule as below: Code Block |
---|
var event = form.load;
var Users = [];
Users = frevvo.userIds();
EmployeeID.options = Users; |
Add a ManagerID dropdown field. The HR manager selects the manager responsible for reviewing this employee. This is the task list you want the Employee Review form to be sent to. The ManagerIDs can be added through the Options property of the dropdown or fetched from the tenant through Business rules as below: Code Block |
---|
var event = form.load;
var Managers = [];
Managers = frevvo.userIds(“<Your Manager Role>");
Manager.options = Managers; |
Add text controls named FirstName & LastName. The HR manager can enter the employee’s name or they can be fetched through Visual rule builder: - Click Rules in the Guided Designer navigation bar at the top.
Click on the + icon for Create New Rule Click Run Builder Button to open the wizard On the first step enter condition EmployeeID in the first dropdown and select Is filled in the second dropdown Click Next, Select FirstName in first Dropdown, ‘to’ in the second dropdown and userFirstName() function in the third. Click Add Action in the right hand top corner. In new added line Select LastName in first Dropdown, ‘to’ in the second dropdown and userLastName() function in the third. Click Next. Add 2 Actions and set the FirstName and LastName to ‘to empty’ in the second dropdown. Click Finish. This rule will automatically populate the FirstName and LastName for the selected EmployeeID.
Add a trigger control named Launch to the form. When the trigger is clicked the form will launch a new Employee Review workflow and put the first step task on the selected Manager’s Task List. Add a Business Rule to call your Employee Review Workflow via the http.get method. The rule shown below runs when the user clicks a Launch trigger button. The rule appends frevvo _data URL parameters to initialize each Employee Review workflow. The rule allows you to trigger the workflow for a different user or role when you browse the workflow URL.
Code Block |
---|
if (Launch.clicked){
var myurl = WorkflowToLaunchURL.value;
http.get(myurl + "&_data=(EmployeeID:{EmployeeID},ManagerID:{ManagerUserId},FirstName:{FirstName},LastName:{LastName})");
} |
To test: - Open the Employee Review Launch Form. Select a user from the Employee ID dropdown. The First and Last Name fields are populated with the selected user's information. Select a Manager from the Manager ID dropdown. Click the trigger to run the rule.
- Log out. Log back in with the Manager ID you selected. Verify that an Employee Review workflow task is on the Manager's Task List.
|
In a real case scenario, it is recommended that you:
Create a separate form with all the basic information fields in it. Then add a field where the user filling in that form can add the list of users for whom he wants to start the workflow.
Create a Business Rule which uses http.get method to call your workflow URL. You will have to call this URL multiple times depending on how many users you want to create the task for. You can pass the usernames of those users and basic information data to the workflow in this URL by using _data URL parameter.

If assigning the first step to an email address template, you must set encode=false to prevent the "@" symbol from being encoded in your launch rule. The designer should use the template {EmailAddress!encode=false}.

| To assign the first step to an email address, follow similar steps as above. Instead of a control that collects UserIDs, have a TextArea control in your kickoff form where the user can enter multiple email addresses separated by a comma (in this example, the TextArea control is named UsersProcessed.) Write a rule like this to split the email addresses and send them as _data in the workflow kickoff URL: Code Block |
---|
var count = 0;
var i, url;
var usersProcessed;
if (TriggerFlows.clicked) {
usersProcessed = UsersProcessed.value.split(",");
for (i = 0; i < usersProcessed.length; i++) {
count++;
url = FlowTypeUrl.value + "?_method=post&embed=true&_data=(SubmitterUserId=" + usersProcessed[i] + ")";
http.get(url);
}
SuccessMessage.value = count + " tasks created";
SuccessMessage.visible = true;
} |
The rule to generate tasks will not work unless you are authenticated to frevvo when using that form. frevvo doesn’t allow you to create tasks for other users unless you are logged in. This is a security measure to prevent a a malicious user who has the link to that form from creating spam tasks. |
