How to write a script to show a Date in a Date Field or a Text Label

Hi All,

I am new to SAP BO Design Studio, I have 4 filters (4 Dropdown) Project(, Projectmanager,Project Start, Project End.

Source for application is BW. 

//My Code on "On startup"

DDB_FILTER.setItems(DS_1.getMemberList("Z1PROJ", MemberPresentation.INTERNAL_KEY, MemberDisplay.TEXT, 20));

DROPDOWN_1.setItems(DS_1.getMemberList("Z1PROJMA_PER", MemberPresentation.INTERNAL_KEY, MemberDisplay.TEXT, 20));

DROPDOWN_3.setItems(DS_1.getMemberList("START_EARST", MemberPresentation.EXTERNAL_KEY, MemberDisplay.KEY, 20));

DROPDOWN_4.setItems(DS_1.getMemberList("END_LATFI", MemberPresentation.EXTERNAL_KEY, MemberDisplay.KEY, 20));

//On DDB_Filter "On Select"

DS_1.setFilter("Z1PROJ", DDB_FILTER.getSelectedValue());

DROPDOWN_1.setItems(DS_1.getMemberList("Z1PROJMA_PER", MemberPresentation.INTERNAL_KEY, MemberDisplay.TEXT, 20));

DROPDOWN_3.setItems(DS_1.getMemberList("START_EARST", MemberPresentation.EXTERNAL_KEY, MemberDisplay.KEY, 20));

DROPDOWN_4.setItems(DS_1.getMemberList("END_LATFI", MemberPresentation.EXTERNAL_KEY, MemberDisplay.KEY, 20));

//show Data in Text-Label

//shwo Project_Name

TXT_STRING_VAR.setText(DDB_FILTER.getSelectedText());

TXT_FILTER.setText(TXT_STRING_VAR.getText());

//show Project_Manager

TXT_STRING_VAR.setText(DROPDOWN_1.getSelectedText());

TXT_PROJT.setText(TXT_STRING_VAR.getText());

//show Start_Date???

TXT_STRING_VAR.setText(DROPDOWN_2.getSelectedText());

TXT_PROJStART.setText(TXT_STRING_VAR.getText());

//show End_Date???

TXT_STRING_VAR.setText(DROPDOWN_3.getSelectedText());

TXT_PROJEND.setText(TXT_STRING_VAR.getText());

My problem is, if I execute the application localy, so I see in the Dropdowns for the start and the end Date only a "#".

how can I see the correct data in the Dropdown and in the Text-Label or in a Date Field?

Thanks,

Markus
