Group Configuration Tab

Table 9 describes the fields in the Configuration tab for groups.

Table 9 Group Configuration tab

Field	Description
Name	The name to appear as the label for the group in the process definition.
Description	Short description of the group.
Group Action	The type of group. Groups can be of the following types. • None — See No Action Groups for more information. • If Groups — See If Groups for more information. • Iterate Loop — See Iterate Loop for more information. • Repeat Until True Loop — See Repeat Until True Loop for more information • While True Groups — See While True Loop for more information. • Repeat On Error Until True Loop — See Repeat On Error Until True Loop for more information. • Transaction Groups — See Chapter 11, Transactions for more information. • Critical Section — See Critical Section Groups for more information. • Pick First — See Pick First Groups for more information.
2.x Compatibility Mode	This field is only available for loop groups in process definitions that were migrated from TIBCO ActiveMatrix BusinessWorks 2.x. Checking this field indicates that you would like activity output in a group to be handled using the TIBCO ActiveMatrix BusinessWorks 2.x semantics. In 2.x, activity output was not reset at the start of every iteration of a loop. Therefore, activities in a loop could potentially see activity output from previous iterations of the loop. If you uncheck this field, activity output in loop groups behaves as described in Activity Output and Groups.
Group Action: Iterate
Index Name	The index variable for the loop. This variable will be used to store the current iteration number of the loop. The index starts at one and increments by one with each execution of the loop. See Index Variable for more information.
Variable List	A process variable containing the list you wish to use as the source of the iterations. The group iterates once for each item in the list. Use the button to choose from a list of available process variables for this field. Once a process variable is chosen, the correct XPath expression for that process variable is automatically entered into this field.
Iteration Element	A name to use for the process variable containing the current iteration element of the data supplied in the Variable List field. See Iteration Element for more information on this field.
Accumulate Output	Specifies that you wish to accumulate the output of each execution of one of the activities in the group into a process variable. See Accumulate Output for more information.
Output Activity	The activity in a group for which you wish to accumulate output for each execution of the loop. You may select only one activity in the group.
Output Name	The name of the process variable to store the successive output of the selected activity in the Output Activity field.
Group Action: Repeat-Until-True
Index Name	The index variable for the loop. This variable will be used to store the current iteration number of the loop. The index starts at one and increments by one with each execution of the loop. See Index Variable for more information.
Conditions	The condition that specifies when the loop should stop. The activities in the group are executed once, then the condition is checked. If the condition evaluates to false, the loop repeats, if the condition evaluates to true, the loop stops. The loop continues to repeat until the condition evaluates to true. The condition is specified as an XPath expression and the XPath formula builder is available to help to create the condition. See Chapter 9, XPath for more information.
Accumulate Output	Specifies that you wish to accumulate the output of each execution of one of the activities in the group into a process variable. See Accumulate Output for more information.
Output Activity	The activity in a group for which you wish to accumulate output for each execution of the loop. You may select only one activity in the group.
Output Name	The process variable to store the successive output of the selected activity in the Output Activity field.
Group Action: While True
Index Name	The index variable for the loop. This variable will be used to store the current iteration number of the loop. The index starts at one and increments by one with each execution of the loop. Specifying an index name is optional for While True loops. See Index Variable for more information.
Conditions	The loop repeats as long as the condition specified in this field evaluates to true. The condition is evaluated when the group is entered. If the condition evaluates to false, the activities in the group are not executed. The condition is specified as an XPath expression and the XPath formula builder is available to help to create the condition. See Chapter 9, XPath for more information.
Accumulate Output	Specifies that you wish to accumulate the output of each execution of one of the activities in the group into a process variable. See Accumulate Output for more information.
Group Action: Repeat-On-Error-Until-True
Index Name	The index variable for the loop. This variable will be used to store the current iteration number of the loop. The index starts at one and increments by one with each execution of the loop. See Index Variable for more information.
Conditions	The condition that specifies when the loop should stop. The activities in the group are executed once. If an error occurs during the processing of the activities, and that error does not have an associated error transition, the condition is checked. If the condition evaluates to false, the loop repeats, if the condition evaluates to true, the loop stops. The loop continues to repeat if unhandled errors are encountered, until the specified condition evaluates to true. The condition is specified as an XPath expression and the XPath formula builder is available to help to create the condition. See Chapter 9, XPath for more information.
Suspend (If Still Error)	Suspends the process if the error still occurs when the specified condition is true. See Suspend If Still Error Option for more information about this field.
Group Action: Transaction
Transaction Type	Defines the type of transaction for group. • JDBC • Java Transaction API (JTA) User Transaction • XA Transaction • JMS Transaction
Include in Transaction	Specifies if the Receiver is included in the transaction, when JMS Transaction type is selected.
Group Action: Critical Section
Scope	Defines the scope of the critical section group. • Single Group — specifies that all process instances in the same process engine for the current process definition will be synchronized on the current group. • Multiple Group — specifies that all process instances for the current process definition and any other process definition with a critical section group specifying the same lock resource will be synchronized. If you are synchronizing across multiple process engines, you should select the Multiple Group option. This option requires the Lock resource to be specified in the Lock Object field.
Lock Object	The Lock shared configuration resource that synchronizes critical section groups across process definitions and potentially across process engines.
