Application Stack Service

The application stack service enables an AIS client to interact with multiple applications running in an ongoing EnterpriseOne web client session. The application stack service enables more complex interactions with applications that have cross-form transaction boundaries, for example where you do not want to save the header until the details are added.

The application stack service supports form interconnects in EnterpriseOne to receive data from the resulting form. For example, you may want to use an existing sequence of tasks in EnterpriseOne that involves interacting with multiple forms to perform a transaction: open an initial form; select a record and navigation to a second form; perform an update that might automatically flow to a third form where you enter more data; and then finally complete the transaction. The application stack service allows for this type of interaction with EnterpriseOne forms.

To use the application stack service, you must first create an ApplicationStack object, which contains these three types of operations:

• Open. Open starts a new stack, opening the first form and performing any operations included in the FormRequest.

• Execute. Subsequent actions on that application stack must use the Execute operation, where you can pass an ActionRequest with any actions to be performed on the currently open form.

• Close. You can pass a Close operation to close the stack and any open forms on it.

Each response to a stack request includes the current form which might be the form originally requested, or it could be a new form if navigation to a new form occurred.

Make sure that you are executing actions on the right form. You should use the getLastAppStackResponse().checkSuccess method before executing actions so you can be sure of the current form. You must include the form in the request for actions. If the form in the request does not match the current form on the stack, the actions will not execute.

The sample code in Example - Application Stack performs operations in a stack of applications in this order:

1. Opens the stack first with the Address Book find/browse form (P01012_W0101B).

2. Executes an action to select a record on that form.

3. Executes another action on the P01012_W01012A form and updates the Name field.

4. Executes another action to press the OK button.

5. Executes another action to press the Close button on W01012A to close the form.

6. Closes the stack.
