| 1 | = User interface and screen flow = |
| 2 | |
| 3 | The Requea platform provides user action flow to design, manage and extend user interfaces. Those user interface flows are called user actions or "actions" and are attached to entities. |
| 4 | |
| 5 | User action define the flow of operation calls and screen that the user will see. |
| 6 | |
| 7 | For example, the list user action is commonly defined with 2 steps: |
| 8 | |
| 9 | |
| 10 | * step 1: search the database, retrieve the records (entities) and return the result as a variable ("data") |
| 11 | * step 2: show the result (the "data" variable) as a list. The list may be a simple list, a multiple column table or a tree view for example.[[image:actions1.png]] |
| 12 | |
| 13 | For more information about user actions, you can view the following articles: |

| 27 | == instance action == |
| 28 | |
| 29 | An "Instance" action is an action that is available on one entity. (the instance). |
| 30 | |
| 31 | For example |
| 32 | * edit is an "instance" action: it work on one particular record |
| 33 | * list is not an "instance" action: it does not work on a particular record. It shows all the record |
| 34 | * new is not an "instance". It creates a new record, but does not start (work) on a particular record |
| 35 | * duplicate is an "instance" action. It copy an existing record (therefore, it works an a particular record). |
| 36 | |
| 37 | Instance actions should be checked as "Instance". |
| 38 | |
| 39 | Instance action: |
| 40 | - they are listed in a detail page, not listed on a list page |
| 41 | - the platform loads the instance and put it in the "data" variable. This is done automatically. |
| 42 | |
| 43 | == Visible Script == |
| 44 | |
| 45 | The visible script is used to hide / show actions for the user based on the context. The script is executed in the context of the instance object so the properties are accessed directly |
| 46 | |
| 47 | Examples of "visible script": |
| 48 | |
| 49 | {{code language="JavaScript"}} |
| 50 | |
| 51 | myProp == true |
| 52 | |
| 53 | myStatus == “Open” |
| 54 | |
| 55 | rqUser != null && rqUser.sysId == System.UserId |
| 56 | |
| 57 | System.User.hasAccess(“56647747477737733”); |
| 58 | |
| 59 | System.User.hasListAccess(data.sysWrite); |
