You get the class cast exception because method findInViews() does not return an IWDWindowInfo.

See the other thread by Mathi S. There I gave sample code using findInWindows().

Hi Bharathi,

you are trying to cast an IWDViewInfo to IWDWindowinfo.

Please look at this for a correct usage.

Stefan

P.S.: Forget my answer, Armin was quicker than me.

Hi Armin,

some day the amount of my daily work didn't allow me to contribute any longer as seriously as i always tried to do in the earlier days of SDN.

And, even worse, since Web Dynpro was and is still evolving in a tremendous speed, if you don't keep up to date with the material (since there's a lack of spare time) you're getting "off-topic" quite quickly.

But i was always there as a passive member...this might change again

Nevertheless, nice to meet you again.

Barathi,

i'm not quiet sure, what you mean by "calling a view in dialog mode".

A view just defines layout and behaviour of a rectangular area of the user interface. If you put a view into a window and use the code snippet mentioned earlier, you'll get a modal dialog containing the view contents.

If you don't want this, you even have to embed the view into a window. A view is not "able to live" without a window.

Please have a look at the <a href="http://help.sap.com/saphelp_nwmobile71/helpdata/en/44/7e0d1ff9a63abee10000000a155369/content.htm">SAP Help Files</a>.

Hope that helps.

Thanks...I agree with you, View cant live without window.

Say I have window called MainWindow..It has 2 views say Mainview, DialogView.

both are embeded into MainWindow.

When I click a Button MainView, Is it possible to open the DialogView in Dialog mode?

BM

If you want to replace a view1 by a view2 inside the same window, embed both views into the window and navigate from view1 to view2.

Armin,

Im not sure whether Im explaining properly or not.. User has to see both the Views...MainView will be in Parent and Dialog needs to be shown in Dialog mode..

Is it possible with embedding in same window? If yes how to do that..

Bharathi,

please clarify, do you want to:

1. display MainView in the (let's call it) "main area" of the browser and DialogView in an own separate (modal) dialog window if the user presses a button -or-

2. display MainView in the "main area" of the browser and DialogView in an own separate (modal) dialog window <b>without</b> the user doing anything -or-

3. display MainView and DialogView in the "main area" of the browser?

Thanks for your patience...My MainView & DialogView both are in <b>same window</b> say "Main area".

When I click on Button on Mainview I wanted to <b>open Dialogview in Dialog Mode</b>...

Here I have only one Window & 2 views..Dialogview needs to be opened as popup..

Is it possoble?

Bharati,

if you embed two views into one window (without using a ViewSet), only <b>one</b> view will be visible (MainView or DialogView).

Let's call the window of the main area "MainWindow".

There's no need to place DialogView into MainWindow despite you want to navigate from MainView to DialogView inside of MainWindow (like Armin stated).

The simple solution is to create a new window called "DialogWindow" and follow the steps of the code snippet in the thread posted earlier.

Of course it's possible to embed multiple views into one window, but only one view is active and visible inside of a window at a discrete time.

If i got you right, you want to place a button inside of MainView (currently visible inside of MainWindow) and as a reaction open the DialogView (in the newly created DialogWindow).

This is exactly what the code snippet already mentioned does.

Hope that helps.

I think we have a slight misunderstanding here. When you say "window" you probably mean "browser window". But that's not the case. For a popup dialog (which is not displayed in its own browser window), you also have to create a separate Web Dynpro window. Just try it.
