Overview

Actionflows can be used to pass data between screens,  itMoving data between screens is achieved through an ActionFlow and form fields on a screen. In this example, we have a Company Name form field on Screen 1 that we will pass to Screen 2 using an actionflow. This is illustrated below:

Passing Data between Screens

This setup assumes Screen 1 has Company Data already displayed on it. Example company data is available from the Learning Centre. See Designing Screens for guidance on setting up screens.

see Understanding Actionflows.

Step 1  Create the Actionflow

1. Find Screen 2 in the repository and dragging it onto the screen 1 canvas. PhixFlow automatically creates a button with an actionflow that opens screen 2; see Adding a Button to Open a Screen.
2. Right-click on the new button and select Display Actionflow to open the actionflow diagram.

Step 2  Configure the Actionflow

1. In the actionflow diagram, in the Inputs panel, click on the On-Click Event and select the source of your data. PhixFlow opens the Mappings window.

   If you need to change the mapping later, to reopen the Mappings window, right-click on the line between the source of data and the connection point, then click.  Add Mapping.

2. Drag the attributes you want to pass to the next screen from the left to the right box.
   In the example screenshots, we will pass on the Company Name.
   
   
   
   
3. In the example above, the connector called screen only opens the screen. In this case we need to pass data. This means we need to remove the connector and create a new one.
   To remove the connector, in the actionflow, right-click on the connector to screen 2 and select Remove Connector, then Confirm the removal.
4. Connect the Inputs →  in connection point to Open (Screen 2). In the popup, select Form, which allows data to pass. When prompted select Screen 2.
5. In the Mapping window, map the attributes you want to pass to Screen 2. For this example, we will pass on Company Name. 
   
   
6.  
7. Close the actionflow.

Step 3  Test the configuration

1. Open the screen 1 canvas and switch to Application Mode; see Design and Application Mode.
2. In screen 1, edit a Company Name and click the button.
   Screen 2 opens with the data for the Company Name attribute including the latest edits.

Passing a Calculated Value to Another Screen 

This example builds on the example above. we will now insert a calculated value into the actionflow created above to add a value that then gets passed to a second screen.

Step 1 Update Screen 2

1. Open Screen 2 and add a form field from the palette that will be used to hold the calculated value we pass across. In our example this is called, CalculatedValue.
   
2. Close the screen.

We now need to tell the actinflow about this change

1. Open Screen 1, unlock it if necessary, right-click on the button that opens Screen 2 and select Display Actionflow.
2. Open the Screen 2 node from the actionflow, from the Input Connection Points open the component where the data will be displayed by double-clicking on it. In our example this is Screen 2.
   
3. In the window that opens, in the Attributes section, click Attributes and from the screen that opens drag the new CalculateValue filed into this attribute section.
   

Step 1  Update the Actionflow

1. From the context toolbar drag a  Calculate onto the canvas. Provide a useful name. In our example this is called CalculateValue.
   1. In here you can perform any calculation see Calculate Node. Save your changes.
2. Remove the connection between in and Screen 2.
3. Connect the in connection point to the  Calculate.
4. Connect CalculateValue to Screen 2 using the Screen 2 form.

Updating Values on an Existing Screen

PhixFlow can update the values on a screen, for example a user enters a date and needs to calculate the number of working days to that date.

1. Add a button to your screen.
   1. See Designing Screens.
2. Right-click on the button, select  Add Actionflow.
3. Create you actionflow to perform the required functionality, for example calculate the number of working days until a selected date. See Understanding Actionflows for assistance.
4. In the connection points click  Add New:
   1. Provide a meaningful Name.
   2. Select Output. 
5. In the screen that opens select the form you wish to write the data back to. Note you can only write back to a form field, you cannot write back to any other view type.
6. Map your outgoing attributes to the available attributes. See Wiring Actionflows.

When the actionflow runs it will output the value from the actionflow to your original screen.
