Avoid rendering of (view,component Usage embedded on TAB) on Timed Trigger

Hi,
I have a WD application build based on header ( icons; normal label; input elements ) , a timed trigger and a tab strip which has 3 tabs. The 3 tabs have View container element for whcih i am attaching 3 views of the same component . TAB A part which i am viewing holds a image. The Timed Trigger is needed to enable icon on the header. This is happening well after my delay time of 60 SECS. But this one is having impact of regenerating the image again ( due to the rendering ) which is not at all required. I want to have the rendering only for the above header part only. But as i heard from Thomas post that after the phase cycle is done. rendering loads all the views, component usages embedded for the VIEW.
conditonally i am doing the action of CANCEL NAVIGATION in WDDOBEFORENAVIGATION when Timed Trigger fires.Due to this one i could avoid the MODIFYVIEW calls of the respective views embedded; but i could not avoid the rendering of the IMAGE ( TAB A ).
Is there any way to avoid the rendering on those tabs part ( 3 views embedded ). I could see that DELTA rendering is enabled for my sap version but it would be not much help.
Thanks and Regards,
Satish A.

Hi Alex.
I already tried this. But a bit different. One of my component should have different entry views. So I defined multiple interface inbound plugs in the window of the subcomponent. In the corresponding (inbound) handler methods of the window I fired corresponding outbound plugs which were connected to different views. The main component had different links which were connected to the corresponding interface inbound plugs of the embedded component.
When I clicked the first link, the correct view of the subcomponent was shown. When I then clicked the next link which should show another view of the same subcomponent the corresponding inbound handler was called but no navigation was done.
Now when I rest the component before navigating everything works fine.
But thanks for the hint.
Cheers,
Sascha

Dynamic create Component usage and embed it in view container

There is a view_container_uielement VC_TEST in view V_MAIN, in wd component ZTEST.
I created a web dynpro component named ZWDR_TEST and add it into the wd component ZTEST.
    gr_comp_test = component->create_cmp_usage_group(
      name = 'TEST_GROUP'
      used_component = 'ZWDR_TEST' ).
    lr_comp_usage = me->gr_comp_test->add_component_usage(

    if lr_comp_usage->has_active_component( ) is initial.
      lr_comp_usage->create_component( component_name = 'ZWDR_TEST' ).
    endif.
    ifc_test ?= lr_comp_usage->get_interface_controller( ).
I thought the wdr ZWDR_TEST was embeded in the view V_MAIN in the position VC_TEST by the embedding_position parameter.
But in the result web page, there is no ZWDR_TEST in the position of VC_TEST.
Could any one explain why?

Component usage - use view of std comp

hi friends,
is it possible to just use one single view( not the main window) of a standard component in another Z component using component usage?
if yes coul dyou tell me the steps... and how to bind the context nodes too, could you please tell ?
how to find which context nodes to be binded in the wd_initialze_usage method?
do i need to create all teh context nodes of the view of std component, which I am using as component usage in Z component controller??
how to get the fields/table etc in editable mode?
how can i enhance that std view in Z component so taht those changes to that view is specific to that Z component?
i m sorry too many questions but i needed some info on the component usage.. Please forgive me if its too many questions..
kindly let me know and your thoughts will be very helpful....
thankyou
RDSingh

Hi RDSingh,
Yes it is possible to load a single view of a standard component to any zcomponent.To do that :
1:) First create a component interface of the view in the statndard component which you want to use.
2:)Regarding the context nodes ,the nodes which are used in the view have to be binded with the context nodes of the
Component Controller to select the context nodes you can go at web UI and press F2 to get all the details.
3)After the Component interface is completed it is available to be loaded into any Z component.
4)Go to the Z component and in the Component usage add the component inerface created earlier.
5)Next you need to delegate the outbound plugs of this component usage to the window.
6)Now the view can be used like a normal view of the component.
I am a newbie in this field myself so pardon if i cant explain u all the details but you can read book SAP CRM WEB-CLIENT Customizing and development to get full knowledge

Using only 1 view from a component ( usage )

hi experts..
I have a component C1 with 7 views...
I have another componet C2 in ehich i want to use only 1 view of the component C1 rather than the entire component...
How can i do that...
jagruti

Hi again.
can u make it more simpler sascha..
In the component controlelr of C1 create en event
(mark as interface).
Steps below r not clear.....
Then in the actíon handler method of C1 fire this
event.
The action handler method assigned to the back button in the view you want to use in C2. Here you can use the wizzard to fire the event in the component controller. There should be a fire_... method in the component controller now.
In the controller of view in C2 which contains the
ViewUiContainerElement create an event handler method
for the event of C1. In this handler you fire an
outbound of the view which navigates to another view
in C2.
this is described in the above mention thread. In C2 you created a viuew with the ViewUiContainerElement which embedds the view with the back button of C1.
Go to the attrib utes tab of this view and add the usage of C1 here.
Then go to the methods tab of this view and create a method handleBackEvent and choose event handler. In the event columen make a F4 and select the event of the component usage C1. Hit enter.
Create an outbound plug in this view which should be use to navigate to the view in C2 you want. Then go to the event handler method just created and fire the outbound plug.
Do not forget to connect the outbound to the inbound of the view you want to navigate to.
sorry for bugging u..
No prob.
jagruti..

How to view lifecycle for component usage

Greetings-
I have declared use of one component to another in the diagram view. I initially set the lifecycle to "CreateOnDemand" using the "New Component Usage" wizard but now I'd like to change this to "Manual". However, I don't see the lifecycle when I view the properties of the referenced Component in the diagram view. How do I find/change this?

Hi,
In WebDynproExplorer expand the "UsedComponents" node under your component .
Double click on the usedComponent and you can change the lifecycle property.

Component Usage / Interface Views

Hi Experts,
I have added two fields in CPGOE_DETAILS/ovefdetails view through AET.
Now I want to attach search help to those fields through compoent usage.
So I have created component usage of BP_HIER in the CPGOE_DETAILS.
I am able to call the search help view : SearchHelpNodesVs because it is default view in Interfave view SearchHelp for the first field.
for the second field i want to call the view : SearchHelpVS which is also available in interface view SearchHelp.
Please suggest the solution.

Hi Naresh,
the window SearchHelp has two different inbound plugs which you have to use.
- IP_SEARCH_NODES opens BP_HIER/SearchHelpNodesVS
- IP_SEARCH_TREES opens BP_HIER/SearchHelpVS
Just use the correct inbound plug to get the search you want.
Best regards
Matthias

WDA Component Usage - used component's point of view

Hi folks!
Component Usage is a real nice feature of WDA. The using component knows exactly, when which other components are used.
But what about the used component's point of view:
How can a used component find out if it is currently running natively or as a used component and who is the using component?
Alternatively: How can the using component hand over initialization information (parameter) to the used component the used component has access to in component controller method DOINIT?
Background: In my scenario the used component has to "turn right" when it is used by component A and it has to "turn left" when it is used by component B and it has to go straight forward when it is running in "native" mode..
Thanx in advance for any hint!
Kind Regards,
Volker

hI Volker
    You can implement the component usage by implementing interface method or interface node.
1. Interface method :-
   Here the using component can access methods of used component.
So in your used component you have three method for 1. TURN RIGHT 2. TURN LEFT 3. STRAIGHT
so from comp A you call TURN RIGHT
From component B you can call TURN LEFT.
Make Straight default which can run in "native" mode..
That is if you want to implement from using component's view.
2.You can take a node in your used component as interface node which must be populated by values from other component.
From your using component you can pass the required value .
Now in your used componentcontroller DOINIT method call that interface node and in the make some condition according to the value it get from using component.
But I don't think in this it can run in "native" mode.
However i dont have that much idea about whether the in used component we can keep any log like where it has been used and how.
Thanks & Regards,

Actually it is pretty simple. From the embedded view you can use the APIs to get access to the hosting window object.
data l_api_v_new_attachment type ref to if_wd_view_controller.
l_api_v_new_attachment = wd_this->wd_get_api( ).

How to switch between different instances of component usage?

Hi All,
Need your help.
My application is about "Program Management", there is a table on the upper level which displays several program header data. in the lower level of the screen, I have a view container in which I embed another component to display program details.For instance,if you make a lead selection on one row of the table above, then the lower part will display the program detail.
Here is the problem: e.g. first, I make a selection on program '001', then I'll create a component usage of the program detail and I put it into a component uage group, second, I make a selection on program '002', then the same like above, I create another component usage and put it into a component usage group. Now I have two instances of program detail component usage, when I select program '001' again, how can I switch back to program '001' detail.
So, I'm trying to achieve multiple instances of program detail so that user don't need to wait for loading program details everytime.
Thanks in advance.

Hi Aaron,
As you are using two separate components, they would be having two separate views to display the required information.
In the onleadselect of your main view ( where you are using the individual views of the other components via the viewcontainerUI ), you have to embed the following code:

lo_api_main = wd_this->wd_get_api( ).
CALL METHOD LO_API_MAIN->FIRE_PLUG
 EXPORTING
 PARAMETERS =
 PLUG_NAME = 'OP_TO_TWO'
Create two outbound plugs in your window, and link them to the inbound plugs of the individual views of used components.

Timo,
It is supposed to pick up the image from the content server and display on the page.
I have tried the following, it worked.
1) Checked in the image in the content server with content id : SAMPLE_IMG
2) modified the code as
<af:image id="img3"
inlineStyle="border-color:Black; border-width:1px; width:85px;height:120px;"
source="#{documentsService.latestReleasedVersionURL['UUCM#dDocName:SAMPLE_IMG']}"
rendered="true"/>
Now that, I want to store the value "SAMPLE_IMG" in a field in a table, and want my application to pick up that value.

How to use one DC's view/component/appln in another DC

Hi All,
I am new to DC concept. I am trying to use one DC's component in another DC. I have done following steps.
a)Created two DCs A and B
b) DC A's 'New Public Part-->Entity Type(Web Dynnpro Component) I selected component
c) Add Used DC in B, I added A's component
 From this point onwards I am not getting any clues. How do I call A's component in DC B. Please guide. Any examples will be great.
Thanks and Regards,
Ganga.

Hi Gangadharaya,
Just tell me do u want to display a view, use some context or use some methods defined in other controller.
So that i can help you in the same direction.
Component Usage
Suppose you have following scenario:
1) DC2 has component Comp2. In this dc you read the context a value and stores it in context named "Ctx_value".
2) DC1 has component Comp1. Here you want to read the Ctx_value from comp2.
In Comp2 create a method getValue()
public java.lang.String getProcessId( )
 return wdContext.getCurrentElement().getAttributeValue("Ctx_value");
In the interface controller of Comp2 click on properties tab and add reference to the cont2 controller. Now create a method here in interface controller to get the value of Ctx_value
public java.lang.String getValue( )
 return wdThis.wdGetComp2Controller().getValue();
Expose the Comp2 as public part now.
In DC1 add DC1 as used DC.
Build both dc's
In Comp1 create Component usage by name Comp2Usage to Comp2.
Now you can access the method getValue() from interface controller of Comp2.
wdThis.wdGetComp2UsageInterface().getValue();
This is how you can access a value of Context. Same can be done by direct binding.
View Access
If you want to access a view v2 in comp2 then goto windows in comp1 and embedd an existing view and in that select the interface view of comp2. The default view in comp2 can now be displayed in comp1.

No component usage created in enhanced web dynpro component

Hi experts,
I am facing the following problem:
I'd like to enhance a web dynpro component in order to add a popup window. The popup is triggered by the process_event method. So far everything works just fine.
But the popup needs to know some context attributes from the main component, and I cannot create a component usage in order to set the context mapping.
Does anybody know how to solve this issue?
Thanks and regards
Jan Phillip Höft

Hi!
Thanks for your answers first of all.
I need the popup to be a stand alone web dynpro component, so I guess the assistant class doesn't do the trick because I can not access it in the popup component.
The popup is called when the business object is saved. So that the user is asked to notify other users that the document has changed. In this popup the user should fill in the message and click a button to send it and close the popup.
So I tried the OBN approach as well but with two problems :
1. I cannot close the popup component by coding (button click) because it has no direct parent component
2. The save event is not run through properly so the document stays locked by the user. But I didn't look into this yet.
So it would be perfect to have an embedded popup component which is based on a stand alone web dynpro application so it can be closed properly but it need at least access to the guid of the main component.
Anybody got an idea for this?
Thanks and regards

PDF Viewer component that works in NetBeans VWP

Hi All,
I am looking for a PDF Viewer Component that will work with NetBeans VWP. Ideally, this would be something that I could load into the Pallette and drop on a web form for use, then dynamically call up a document for display within the control. (Actually, IDEALLY, this would be a multi-document viewer, i.e. PDF's Word files, text files, etc.). It does not have to be a free tool - though free would be nice. I have checked out the Acrobat Viewer Java Bean but from everything I can find on that, it appears to be something that can be used in Java Apps, but not web apps. If I am wrong about this, can someone please correct me and link to web app usage (as applied to VWP - JSP & JSF).
Any help here would be greatly appreciated. I noticed a lot of references to IText on this forum and I'm in the process of checking it out now. But I have not seen anything on IText regarding an actual viewer component.
Thanks,
Dennis

I don't believe iText has a viewer as I know of. If Adobe has a java bean then you can create an applet for the client side to display the viewer.

Avoid rendering of (view,component Usage embedded on TAB) on Timed Trigger
