TAB "Element Properties"
The TAB "Element Properties" contains the configuration for
-
UI element value horizontal alignment (left, center, right)
-
UI element width configuration (percentage, pixel)
-
UI container horizontal alignment (left, center, right)
-
UI element visible rows (1 row, 3 rows, 6 rows)
-

TAB "Data Mapping"The TAB "Data Mapping" contains the attribute type related mapping of the UI element -
enum
-
generic error code
-
db error code
TAB "Data Validation"The TAB "Data Validation" contains the attribute type related validation, default value and mandatory specification of the UI element based on the BO attribute configuration in SubTAB "Values and Validation". -
default value
-
enum mandatory
TAB "Events"The TAB "Events" contains the events and related "Action" and "Validation" scripts of the UI element. -
onClick
-
onDoubleClick
-
onBlur
-
onChangeFor each UI element the related event action is displayed at the right side of the UI element. In case of a validation error a default error message is displayed at the top right of the UI page and the action script is not executed.
TAB "Visibility"
The TAB "Visibility" contains the visibility configuration and the "Visibility" scripts of the UI element.
-
enabled/disabled
-
visible/invisible
-
mandatory/not mandatoryFor each UI element the visibility can be changed by the checkbox "Visibility Toggle".
Exercise
In this exercise you will get familiar with the configuration possibilities of the UI element by completing the UI TABs as described above. You can test the implementation in UI Page Preview, in the Preview of the Frontend Service Model and optionally in the xAPPnow User Portal.

-
Step 3: Open TAB "Implementation" SubTab "Element Properties" and select each UI ListBox on "H-Alignment" to configure the values [Left], [Center], [Right]
-
Step 4: In next row select the UI ListBox to configure width [50%] and width [200px]
-
Step 5: In row "Container (H-Alignment)" for each UI ListBox:
-
Select each UI ListBox to configure width [50%].
-
Select button "Span" to configure H-Alignment [Left], [Center], [Right] of the UI element
-
Step 6: Select each UI ListBox for "Visible Rows" property to configure Visible rows with [1 row], [3 row], [6 rows]
Exercise 3: TAB "Data Mapping"
-
Step 1: Drag&Drop attribute "person.gender" from TAB "Data" into second free span of second row to open dialog "Select Component" to add the corresponding UI Label and UI ListBox to the UI page.
-
Step 2 Repeat Step 1 select ListBox without Label for attributes
-
"genericError.errorCode"
-
"errorDB.errorCode"
Exercise 4: TAB "Data Validation"
-
Step 1: Drag&Drop attribute "academicLevel" from TAB "Data" into the third free span of second row and select "ListBox" in dialog "Select Component" to add the corresponding UI Label and UI ListBox to the UI page.

"continent"
-
Step 3: Select the first UI ListBox and open TAB "Implementation" SubTab "Events" to specify event type "onClick"
-
Step 4: Implement the action script, which displays the related event action at the right side of the UI element.
localData.eventType.onClick = globalDef.enums.Tutorial.UIM.DEF.EventMessage.ON_CLICK;
-
Step 5: Repeat Step 3 and 4 for the other UI elements to specify further event types and related action scripts, which display the related event action at the right side of the UI element.

event type "onDoubleClick"
localData.eventType.onDoubleClick = globalDef.enums.Tutorial.UIM.DEF.EventMessage.ON_DOUBLE_CLICK;
-
event type "onBlur"
localData.eventType.onBlur = globalDef.enums.Tutorial.UIM.DEF.EventMessage.ON_BLUR;

-
Step 2: Implement the action the validation scripts, which display the related event action at the right side of the UI element in case of no validation error.
-
action script "onClick" event
localData.eventType.onClickValid = globalDef.enums.Tutorial.UIM.DEF.EventMessage.ON_CLICK_VALID;
-
validation script "onClick" event
localData.eventType.isValid
-

-
action script
-
"onDoubleClick" event
localData.eventType.onDoubleClickValid = globalDef.enums.Tutorial.UIM.DEF.EventMessage.ON_DOUBLE_CLICK_VALID;
-
"onBlur" event
localData.eventType.onBlurValid = globalDef.enums.Tutorial.UIM.DEF.EventMessage.ON_BLUR_VALID;
-
"onChange" event
localData.eventType.onChangeValid = globalDef.enums.Tutorial.UIM.DEF.EventMessage.ON_CHANGE_VALID;
-
validation script
-
"onDoubleClick" event
localData.eventType.isValid
-
"onBlur" event
localData.eventType.isValid
-
"onChange" event
localData.eventType.isValid
Exercise 7: TAB "Visibility"
-
Step 1: Drag&Drop attribute "toggleVisibility" from TAB "Data" into the third free span of second row and keep default in dialog "Select Component" to add the corresponding UI Label and UI CheckBox to the UI page.
-
Step 2: Select the first UI ListBox and open TAB "Implementation" SubTab "Visibility"
-
Step 3: Click at visibility type "Enabled" and select state "Script"
-
Step 4: Implement the visibility script, which toggles the visibility "enabled" and "disabled"
localData.toggleVisibility
-
Step 5: Repeat steps 2..4 for second and third UI ListBox for visibility type "Visible", which toggles the visibility "visible" and "invisible"

Step 3: Click button “Search“ to open dialog "Select or Create Submodel" and select UI page "ListBox" with double click
-
Step 4: Right click on button flow to set label with "Exit" flow.
Exercise 9: Test the UI Page
-
Step 1: Open UI Page and click button "Preview" in the toolbar to directly test the UI page within the UI editor
-
Step 2: Optionally publish the frontend service model and test the UI page in User Portal
