Also Check this code.. r u missing any thing..?

IWDWindowInfo windowInfo = (IWDWindowInfo)wdComponentAPI.getComponentInfo().findInWindows("Name");

IWDWindow window = wdComponentAPI.getWindowManager().createModalWindow(windowInfo);

window.setWindowPosition (300, 150);

window.show();

If you are really serious about fixing this issue

Try to check the followig

cardinality of the node , make sure that their is a valid element under popupnode.

where you have set the attribute which contiains the window handle.

Hi Sushma,

Move the PopUpAttribute directly under context.

while storing the window use this code

IWDWindowInfo windowInfo = (IWDWindowInfo)wdComponentAPI.getComponentInfo().findInWindows("PopWin"); 
IWDWindow window = wdComponentAPI.getWindowManager().createModalWindow(windowInfo); 
window.show(); 
wdContext.currentContextElement().setPopupAttribute(window);

For closing the window use the following code.

IWDWindow window = wdContext.currentContextElement().getPopUpAttribute();
window.hide();

Hi,

I created 2 windows here.PopApp and PopWin......

Here output ios coming.By clicking popup button in PopApp Window it has to show PopWin Window.

For me its showing PopApp Window only.

Please help me.

You have to give the windowname of "PopWIn" as parameter to the following code

IWDWindowInfo windowInfo = (IWDWindowInfo)wdComponentAPI.getComponentInfo().findInWindows("PopWin");

excelLinkWindow.setWindowPosition(WDWindowPos.CENTER);

excelLinkWindow.open();

}

private IWDWindow excelLinkWindow;

OR

Try this

IWDWindowInfo windowInfo = (IWDWindowInfo)wdComponentAPI.getComponentInfo().findInWindows("Name");

window = wdComponentAPI.getWindowManager().createWindow( windowInfo, true);

window.setWindowPosition(125,165);

Hi,

Create a method in component controller and use the following code

//Method

{

IWDWindowInfo windowInfo = (IWDWindowInfo)wdComponentAPI.getComponentInfo().findInWindows("PopWin");

window = wdComponentAPI.getWindowManager().createWindow( windowInfo, true);

window.setWindowPosition(125,165);

window.setWindowSize(300,240);

window.open();

}

//end

//@@begin others

IWDWindow window;

//@@end

Call this method from u r action in PopApp view

{

//@@begin onActionClosePopUp(ServerEvent)

wdThis.wdGetPopUpAppController().ClosePopUp();

//@@end

}

In Component Controller

public void ClosePopUp( )

{

//@@begin ClosePopUp()

IWDWindow window = wdContext.currentPopUpNodeElement().getPopUpAttribute();

window.hide();

window.destroyInstance();

//@@end

}

[Former Member]

Hi,

I think u can use this following method

public void ClosePopUp( )

{

window.close();

}

I hope u declared window like this(Global declaration)

//@@begin others

IWDWindow window;

//@@end

Hi,

Did you store the handle of the window to the attribute that you are using in close popup?

Ex:

IWDWindow window = wdComponentAPI.getWindowManager().createWindow( windowInfo, true);

wdContext.currentPopUpNodeElement().setPopUpAttribute(window);
