[Former Member]

Hi

I am trying to pass a parameter through outbound plug to the the other view that has this inbound plug to it.so i just now wanted to know the process of how to get this passed parameter in the other view.

so any help in this willl b highly appreciated.

Hi,

Have you tried this

WDProtocolAdapter.getProtocolAdapter().getRequestObject().getParameter(key)

Tnx guys

this works for views in the same component but i want to achieve this same within two different compnets

meaning one view in one componet to other view in another component

Hi Sudder,

A work around for this can be to create a context in the component controller ( or the custom controller, if you have used any ) of the data-type that you want for the parameters to be passed.

Then map these parameters from the controller to both the views.

Set these parameters in the parent view and access them from the child view.

In this case, you will not require to pass parameters with the plug.

Hope that'll help you.

Regards.

Hi,

Suppose i have two views firstview and secondview.

1)Create an outbound pulg(say tosecond) in Firstview say with a parameter of type String .

2)create an inbound plug(say fromfirst) in secondview with a parameter of type string

fire ur tosecond plug from firstview.

wdThis.wdFirePlugTosecond(wdContext.currentContextElement().getCtx_name());

Now go to secondview u fill a corresponding event handler in

for ur inbound plug with a parameter.

In that event handler u can set any context varibale with that parameter.

public void onPlugfromfirst(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent, java.lang.String hello )
  {
    //@@begin onPlugfromfirst(ServerEvent)
    wdContext.currentContextElement().setCtx_String(hello);
    //@@end
  }

No need to write anything in init().

If you want to pass parameters between two components you have to use Events. Basically fire event with parameters from one component, and subscribe to that event with event handler in another component. In the event handler code, you can read what ever the parameters are sent.

Navigation plugs works only within the component.

Hi Sudeer,

Assume you have two Web Dynpro components. Each has one view: view1 and view2. You should define inbound plug in the appropriate Interface View of the second component. Interface View is created automatically for each Window you add to the component. So here are the main steps:

<OL>

<li>Create a new window in your second WD component (or use existing one)</li>

<li>Embed view2 to the window from step 1</li>

<li>Open appropriate Interface View for the window from step 1: goto Component Interface->Interface Views-><WindowName>InterfaceView </li>

<li>Create Inbound Plug on the Plugs tab and define necessary parameters for it (it's the same thing as define inbound plug for a view)</li>

<li>Add the second WD component to the Used Web Dynpro Components of the first WD component</li>

<li>Open existing Window (or create new) of the first WD component where the view1 with outbound plug is embedded</li>

<li>Embed Interface View or a Component Instance <WindowName>InterfaceView of the second WD component to the window from previous step</li>

<li>Connect outbound plug of the view1 to inbound plug of <WindowName>InterfaceView</li>

</OL>

Remember that parameter names and parameters order should be the same for inbound and outbound plugs.

Hi Sudeer,

to get the parameter no need to code at the doinit. When you are declaring parameter for out bond plug, declare the same for inbound.

And when outbond plug is going to fired it'll navigate to the 2nd view and inbound plug action will take place, here you can get the parameter value.

Like i have used in one of my application.e.g.;-

Outbondplug

wdThis.wdFirePlugOnEdit(wdContext.nodeClassifiedsElements().getClassifiedsElementsElementAt(count) .getClassifiedsResources(),filestatus);

in that i m passing Resource and String as a parameter. and i m getting this two value in the corresponding in-plug:-

*public void onPlugfromListview_onEdit(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent, com.sapportals.wcm.repository.IResource title, java.lang.String status )*

{

//code

here you can use title and status coming frm the other view.

}

Hope that'll help you.
