binding input fields in form

[Former Member]

Hey

I got a question with binding inputfields.

I got a table that is binded to my context. Under this table i got a button that opens a new VIEW with a form. This form is binded to the context. My problem is that old contextinput is still in the form if im using it serveral time. How is it possibple to "empty" the context? cause the fields in the forms has olds values

Person

- name

- lastname

- email

And my UILements binding is

textfield1 Person.name

textfield2 Person.lastname

textfield3 Person.email

If you bind UI element properties to attributes inside a (multiple) node, you will always get the values for the lead-selected node element.

ahh,that makes sence..

so how whould you do this?

I got all the data stored in a oracle database. When i start the application, the data is stored in a context that is binded to a table. I got a button to create a new node to the context that represent a form. got any suggestions?

Not sure if I understand your use case correctly.

You have a table filled with data, you want to add a new entry by filling out a form?

In the action handler of the button, create and add a new node element, set the lead selection to the index of this element. Then you can use your existing data binding.

yes thats correct. I want to add a new entry by filling out a form..

I tried this code on the view with the table:

public void onActiontoNewPersonView(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )

{

//@@begin onActiontoNewPersonView(ServerEvent)

IPersonNode bNode = wdContext.nodePerson();

IPersonElement bElement = bNode.createPersonElement();

bNode.addElement(bElement);

int leadSel = bNode.getLeadSelection();

if(leadSel == -1)

++leadSel;

bNode.setLeadSelection(leadSel);

wdThis.wdFirePlugToNewPersonView();

//@@end

}

But im still getting the old value

Simple set the lead selection to the index of the added element, like

bNode.moveTo(bElement.index());

thanx, but i cant find that method on the currentContextElement. This form is suppose to create a new element on the node, but each time i open the form, i get the last element i had opened on the form

Hi Kristoffer,

you put following code in your onPlugIn event.

wdContext.currentContextElement().setInputContext("");

That will solve your purpose.
