Hi Karthi,

Directly it is not possible. You can achieve it by this way.

1> Create 2 Event Handlers say “OK” and “OKTest”.

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

{

//@@begin OK(ServerEvent)

String param = "abc";

wdThis.OKTest(wdEvent,param);

//@@end

}

public void OKTest(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent, java.lang.String paramtest )

{

//@@begin OKTest(ServerEvent)

wdComponentAPI.getMessageManager().reportSuccess("Param : "+paramtest);

//@@end

}

2> Code for popup.

String dialog = "No of Rows : ";

IWDConfirmationDialog confDialog = wdComponentAPI.getWindowManager().createConfirmationWindow(dialog,wdThis.wdGetAPI().getViewInfo().getViewController().findInEventHandlers("OK"),"OK");

confDialog.setTitle("Test Window");

confDialog.show();

Hi Karthi,

You are taking the param of type "com.sap......Parameter"

that’s why it is giving error. what error r u getting?

public void OkTest(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent, java.lang.String paramtest )

i have taken the <b>paramtest</b> of type <b>String</b>.Check the signature of event handler. It will definitely work.

Hi mithu,

public void OkTest(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent, com.sap.IPrivateTestView.IListElement paramtest)

{

pass to customcontroller method

}

This is the parameter i am using,but i am getting error in the ok() method as(The local variable node element may not be initialized) not intialized. How to initialize this parameter..

void ok()

{

com.sap.IPrivateTestView.IListElement paramtest;

wdthis.okTest(wdEvent,paramtest);

}

Hi Karthi,

void ok()

{

<b>com.sap.IPrivateTestView.IListElement paramtest = wdContext.nodeList().createListElement();</b>wdthis.okTest(wdEvent,paramtest);

}

Hi karthi,

For 0..n node use .

IPrivateTestView.IListElement paramtest = wdContext.createListElement();

Paramtest.setAttrr(Value);

wdContext.nodeList().addElement(Paramtest);

Other wise you can change the node cardinality 1..n

Hi,

How will you use the paramaters? Just curious to know.

Are you talking about passing the parameter for the Eventhandler of the Confirmation Dialog?
