The Workflow Designer is a component in UBIK® which appears on many occasions, namely every time when there is a Workflow to be displayed or edited. It features a full re-hosted version of the designer for the Microsoft Workflow Foundation, extended with manipulation capabilities for UBIK® objects.

Toolbox
The Toolbox features a wide range of Activities that cane be used within your Workflows. There are generic activities as well as activities specific for the manipulation of UBIK® objects.

UBIK® activities
| Activity | Category | Purpose (Short) |
|---|---|---|
| DebugMessage | UBIK Control Flow | Writes a debug Text |
| InvokeInterface | UBIK Control Flow | Invokes a UBIK® Interface component |
| InvokeWorkflow | UBIK Control Flow | Invokes a UBIK® Workflow object |
| SendEmail | UBIK Control Flow | Sends an Email To recipients via an SMTP Host |
| AssignToNamedRelation | UBIK Object Primitives | Assigns a Child object via the named RelationName to a Parent object |
| AssignToSystemRelation | UBIK Object Primitives | Assigns a Child object via the given Relation to a Parent object |
| CreateInstance | UBIK Object Primitives | Creates a new instance of a given MetaClass |
| DeleteObject | UBIK Object Primitives | Deletes a UBIKObject (Deep delete by default, ShallowDelete optional) |
| GetObjectsByPropertyValue | UBIK Object Primitives | Queries instances of MetaClass where PropertyName has a certain value |
| GetObjectsByQuery | UBIK Object Primitives | Delivers the result of Query |
| RemoveFromNamedRelation | UBIK Object Primitives | Removes a Child object via the named RelationName from a Parent object |
| RemoveFromSystemRelation | UBIK Object Primitives | Removes a Child object via the given Relation from a Parent object |
| SaveObject | UBIK Object Primitives | Saves the UBIKObject (Deep save by default, ShallowSave optional) |
| SetPropertyValue | UBIK Object Primitives | Sets the Value to the property named PropertyName of the UBIKObject |
| AssignIconToBaseClass | UBIK UI Primitives | Assigns a selectable icon image to the UBIKObject |
| SelectSourceFile | UBIK UI Primitives | Brings up an open file dialog |
| SelectTargetFile | UBIK UI Primitives | Brings up a save file dialog |
| ShowUnsavedObjectsHierarchy | UBIK UI Primitives | Brings up the Unsaved Objects dialog |
| UserDecisionYesNo | UBIK UI Primitives | Brings up a Yes/No dialog with configurable Title and Text |
| UserInputText | UBIK UI Primitives | Brings up an input box with configurable Title and Text |
Design canvas
Property window
Working with the designer
Toolbar
| Item | Purpose |
|---|---|
| Open file | Opens a dialog to load a previously saved UBIK® workflow file (.uwf) into the design canvas |
| Save to file | Saves the current design canvas into a file (.uwf) |
| Toggle breakpoint | Sets/Removes a breakpoint at the currently selected activity (async execution only) |
| Resume | Resumes execution if a breakpoint was hit (async execution only) |
| Delay between activities | Execution delay in Milliseconds between activities (async execution only) |
This control doesn't feature any context menu yet.
Designing workflows
Designing a workflow is fairly easy and typically involves placing, configuring and connecting various Activities. All available activities are listed in the Toolbox on the left side. Use Drag&Drop to place an Activity on the canvas in the middle. Select an activity on the canvas and use the context menu or the Del key to remove it again.
 | Unless the activity is of type FlowChart or Sequence, you will not be able to add more than one Activity to the canvas |
Typically we want to start with a Sequence or a Flowchart, which are both able to host child (nested) Activities
- The Sequence executes its nested Activities sequentially, one after the other
- The FlowChart executes its nested Activities in the order you link them with connecting lines
