Navigation between iviews

Hi all.
I have a portal page with three bsp iviews, one on left side and the other two on the right side, showing only one by time with the possibility to swich them during the runtime.
I need that clicking on a link in the first (iview on the left side), then one of the second iview appears, with some information that depends of the link clicked.
My initial idea was made it with with only one BSP and frames, but my company's client want that we use multiple BSP application, because they said that they can mantain the system more easily (at least they say it...).
I've tried something about iview navigation, but that the new iview appears over the ivew from i realized the call, or that a new broser appears... :-S
Could someone help me? Thanks in advance.
Ricardo.

Hi Ricardo,
to achieve this you can use portal eventing (EPCF) and EPCFproxy in your BSP. This will allow tou to raise an event from one BSP application that will be caught by the other one who can act on it.

Problem in navigating between iviews

Hi,
I have a webdynpro application and a jsp file, I have deployed the webdynpro application into the portal by using webdynpro iview and the jsp file using url iview. I have created a page containing both the iviews. I need to know how to navigate from one iview to the other.
Thanks & Regards,
Amrita

Hi,
To communicate between two ivews you can use ECPF
(Enterprise Portal Client Framework)

Regd Navigation between iViews

Hi,
We have two iViews (webdynpro iViews) in a workset.
I want to create a section called Alerts(iView) in a different workset. This alert iView is also webdynpro iView.
We want to show this Alert iView contents in detailed navigation.
We want to have a iView which will have two links each pointing to one iView in Workset 1. This has to be shown in Detailed Navigation. Is there anyway we could do this with minimal coding and customization.
If you need more information, plz let me know.
I tried Dynamic Navigation and related links, it is not giving me the expected results.
I tried calling one webdynpro iView from another, it is changing the page look and feel.
Thanks
Senthil

Hi RK,
I used AbsoluteNavigation in webdynpro and i am accessing Portal pages through this.
Get the exact PCD location of the specific Portal Page or iView and use them in AbsoluteNavigation.
Make sure that the user has READ permissions to access this page.
Thanks

Communication between iViews

How to realize communication between two iViews of the same window but not the same portal page? I tried with using firing portal events but this doesnt seem to work with Mozilla Firefox. Do you have any other ideas?
The sending iView is a portal application the receiving iView a Web Dynpro for ABAP application (so I cant use JavaScript, I guess).
Thanks!
René

Hi Mrkvicka,
To enable communication between iviews you need to use the EPCF .
You can raise an event in the component of the first iview and define an OnClick event.
this event you can subscribe from the other iview
Refer to this link to get a more clear picture
DropDown Selection and EPCF
also refer to
EPCF
hope this helps,

Navigation between different componets in IC Web Client for CRM 7.0

Once the user click save button in component ICCMP_BT_BUTTON I need to navigate to component ICCMP_BT_SVO that displays the Service Order Data and display the new Service Request that was created.
How can I do navigation between different componets in IC Web Client for CRM 7.0?
Thanks.

Hello,
You can find detailed presentations in the learning maps available on the SAP Service Marketplace http://service.sap.com/rkt-crm for release CRM 2006s, CRM 2007, or CRM 7.0. In case I didn't mention it before, Intent-Driven Interaction (IDI) was first introduced and is only available starting with CRM 2006s and above. In the Interaction Center area, there is a presentation called "Rule Based Automation and Guidance" which covers IDI. I'm not sure if you can access the URL directly, but just in case here it is: [https://websmp104.sap-ag.de/~sapidb/011000358700001162852007E].

How to navigating between layers?( as if they were pages of a book?)

I need a good advice on design and navigating between some different layers.
I am a Adobe Director user, and I am used to think of “navigating between frames”. also frames as pages of a book, while in flash time-frames.
In Director one can navigate between different frames with each containing many components.
And this does not make any conflict since the frames are some kind of pages of a book, you go to any page you want and back again.
I am designing math training application in falsh-CS6, in which the user should be able to navigate from start-menu by choosing an
exercise number and then go to the wanted exercise and then create an exercise by a create_excercise button, there back again to menu to choose another and so on. How I can do it clean in flash?
As I see I have to place everything in the same “frame” in flash, and it becomes little practical and confusing since there
are many things all gathered in the same frame, where they should instead appear in their respective “pages”.
I have done some works in flash: made 4 layers in flash with the following contents:
layer 1: for my menu( contains 3 buttons, q1bt, q2bt, q3bt)
layer 2: for question 1( contains 3 buttons makeQ1bt, chekAns1bt, and gotoMenuBtn)
the same is for layer 3 and 4.
I see no options rather than making different components visible or invisible whole way! but is there a better way?
I appreciate any help.

Flash does allow more than one frame - that is one of the foundations of working with it. You can restrict yourself to using just one frame if you like, but it is not required and very often people use the timeline instead of keeping things in one place.
I have no familiarity with Director, but what you just described sounds like designing using the timeline of Flash. With Flash you can use the timeline in the fashion you just described where different pages occupy different frames of the timeline and you can navigate from one to another. You are not stuck with one frame in Flash... you can create a new keyframe at any point along the timeline and add new/different content to it, while retaining a menu that exists across all pages (or not - it's your choice)..

Navigation between records in a JSP application

Hi,
I would like to know how to provide navigation between records in a tabular form liked JSP application using JDeveloper 3.2
without using the Oracle or Default template.
I can do it with a singular record view but not in a tabular view. I like to know now I can mimic the navigation provided in Oracle template in which the current selected record is hightlighted. Can we navigate between records using Up and Down
arrow key like in Oracle form instead of using Navigation Bar. Please provide details code.
Thanks a bunch,
Khanh Hoang

You can refer to the source code in jbohtmlsrc.zip for deriving your own implementation.

Navigation Masterhead Iview

Hi,
I want remove the text 'Welcome' in the Navigation Masterhead Iview (It's the Iview where show 'Welcome Jean François'.
I've looked in the server:
ootweb-infportalportalappscom.sa.porta.navigation.masterheadprivateclasses headeriview_nls_es.propierties, it has a property called 'Welcome_text' and 'WELCOME_CLAUSE' and I've modified that properties: Welcome_text =, WELCOME_CLAUSE=. But when I open the portal, it's show 'Welcome Jean François'. What it's the right form for remove 'Welcome'?

hi Jean,
this is very easy . You don't have to write any particular code for this.
this you can achieve at the portal front end itself.
<b>System Administration</b>
Portal Display Workset
Goto the themes and open the one which you have already assigned to the user
Now you would be in the edit mode
->Welcome area section.
> property Display of Welcome Area Container >Set this to "none".
This would solve your problem
Cheers

Large number of http posts navigating between forms

Hi,
i'm not really a forms person (well not since v3/4 running character mode on a mainframe!), so please be patient if I'm not providing the most useful information.
An oracle forms 10 system that I have fallen into supporting has to me very poor performance in doing simple things like navigating between forms/tabs.
Looking at the java console (Running Sun JRE 1.6.0_17), and turning on network tracing, I can see a much larger number of post requests than I would expect (I looked here first as initially we had an issue with every request going via a proxy server, and I wondered if we had lost the bypass proxy setting). Only a normal number of GETS though.
Moving to one particualr detail form from a master record is generating over 300 post requests - I'v confirmed this looking at the Apache logs on the server. This is the worst one I have found, but in general the application appears to be extremely 'chatty'
The only other system I work with which uses forms doesn't generate anything like these numbers of requests, which makes me think this isn't normal (As well as the fact this particular form is very slow to open)
This is a third party application, so i don't have access to the source unfortunately.
Is there anything we should look at in our setup, or is this likely to be an application coding issue? This app is a recent conversion from a forms 6 client server application (Which itself ran ok, at least this bit of the application did with no delays in navigation between screens).
I'm happy to go back to the supplier, but it might help if I can point them into some specific directions, plus i'd like to know what's going on too!
Regards,
Carl

Sounds odd. 300 Requests is by far too much. As it was a C/S application: did they do anything else except the recompile on 10g? Moving from C/S to 10g webforms seems to be easy as you just need to recompile but in fact it isn't. There are many things which didn't matter in a C/S environment but have disastrous effects once the form is deployed over the web. The synchronize built in for example. In C/S calls to synchronize wasn't that bad; But when you are using web deployed forms...each call to synchronize is a roundtrip. The usage of timers is also best kept on a low level in webforms for example.
A good starting point for the whole do's and dont's when moving forms to the web is the forms upgrade center:
http://www.oracle.com/technetwork/developer-tools/forms/index-095046.html
If you don't have the source code available that's unfortune; but if you want to know what's happening behind the scenes there is the possibility to trace a forms session:
http://download.oracle.com/docs/cd/B14099_19/web.1012/b14032/tracing002.htm#i1035515
maybe this sheds some light upon what's going on.

Retaining values when navigating between subtabs

Hello everyone
I have a subtab region with 3 tabs in my page. I have some form fields in each tab, when I enter some details in tab1 and click tab2, and then come back to tab1 , my details previously entered in tab1 gets cleared. is there a way to retain these values when navigating between subtabs. all the tabs are based on different VO's
Thanks
Ravi

Here's how I do it...
(1) I always use Sessions. In the main form of my application, I set up the session and I store a single variable: Session.Exists = True. All other forms begin something like this: (It's actually an include-file.)
<cflock ...>
<cfset SessionExists = StructKeyExists(Session, "Exists")>
</cflock>
<cfif NOT SessionExists>
<cflocation ... send 'em back to the home 'cuz their session has expired>
<cfabort>
</cfif>
(2) Now that we know that a session exists, we store various structs in the Session to contain the default or current values that have been used in a particular form. If the Session scope does not contain a particular struct, it is automagically created with appropriate default values.) This becomes "what we display," and when we capture the user's responses, we store them there, even before we validate them. The session pool therefore becomes the vehicle for communication between the various forms.
(3) If we reach a point where a particular piece of information is no longer useful, we delete the appropriate structure from the Session, thereby wiping out the entire set of values at once.
(4) Structs and Arrays can, of course, contain other Structs and Arrays. You can build data structures of arbitrary complexity.
(5) As of late, I have found myself specifying individual CFCs for each logical "object" in my application. This is true object-oriented programming, as best as ordinary CFC techniques can do without plunging headlong into the underlying nether-world of Java. In those CFCs, I deliberately try to conceal just how information is maintained and stored, so that these necessary inter-dependencies within my application are concentrated in just one place. "The structure is 'the object,' and the methods are found 'here and only here.' "

How to remove white fade while navigating between pages?

I created small web page with 4 buttons which each of them leads to other page eg., Home,Gallery, Contacts,Reviews, but when i'm navigating between them there is annoying white flash! Is it possible to remove it?
P.S. I uploaded my site to businesscatalyst Home
Thank you!

That is so strange, I just tried on my OS X Safari and WIN 7 Chrome and everything just fine, but when I'm trying on same OS X Chrome it has white flash while transitioning through navigation. Thanks anyway mac_heibu!

Navigation between applications

Everything is working fine.
My problem is : the parameters whch i am passing are showing in addressbar as query string.I dont want to show them there.
Is there any other way to witch i can pass parameters from one application to other application without displaying at url.

LightSwitch HTML: Don't wait for active promise operations when navigating between screens

Navigation between screens is halted (and the loader is shown) until any active promise operation has completed.
This becomes an issue when a screen started a long loading operation, but the user wants to exit out of that screen. It is easy to cancel promise operations that I started myself, since I have control over when the operation completes. But I don't see any
way to do it for operations started by the framework itself (such as any collection property of a screen).
Is there any solution to this problem?

This becomes an issue when a screen started a long loading operation, but the user wants to exit out of that screen.
There isn't method available to cancel the navigation between screens, you need look into your project, and check why it takes long time to load.
