hi Mani,

U have to clear the previous contents in the result view.

Use invalidate() function to clear the above contents....

write this query in the function of back button..

Hi,

First u map first and second view to component controller

Just u go to the SecondView, in that u create back button and also create action for that.....then go to implementation click onActionBack and write inside that as

onActionBack()

{

wdcontext.<ur Node Name>.invalidate();

wdthis.<ur outbound fireplug name>();

}

u have to give invalidate function in the action button...

like

onActionButton()

{

wdcontext.node.invalidate();

}

or else

declare a function name clearcontent(); in init method;

then

define tht function as follows:

Eg:

wdContext.nodeInputs().currentInputsElement().setName(null);

It will works;;

Hi

I got the same problem, & Solved it by using this code:

In Controller:

<u><i><b>Step1:</b></i></u>

WdDoInit()

{

__Arch__Arm_Project_Search_Input search = new __Arch__Arm_Project_Search_Input();

wdContext.node__Arch__Arm_Project_Search_Input().bind(search);

}

<u><i><b>Step 2:</b></i></u>Create a method in Custom Controller

public void DoSearch( )

{

//@@begin DoSearch()

try

{

wdContext.current__Arch__Arm_Project_Search_InputElement().modelObject().execute();

wdContext.nodeOutput().invalidate();

} catch(WDDynamicRFCExecuteException ex) {

wdThis.wdGetAPI().getComponent().getMessageManager().reportSuccess(ex.toString());

ex.printStackTrace();

}

<u><i><b>Step 3:</b></i></u>

Create another Method:

public void PrepareSearch( )

{

//@@begin PrepareSearch()

__Arch__Arm_Project_Search_Input search = new __Arch__Arm_Project_Search_Input();

wdContext.node__Arch__Arm_Project_Search_Input().bind(search);

//@@end

}

<u><i><b>Step4:</b></i></u>

Call this method in Back Button.

wdThis.WdGetArchController().PrepareSearch();

it will clear all your previous data and shows fresh data.

This will solve your Problem.

Hi,

Once check the mapping between the first view ,second view and the component controller.Check if the mapping is done properly or not.

Hi,

this u give this code,all the previous element be deleted

onActionButton();

wdcontext.<ur node name>.invalidate();

wdThis.WDfireplugtofirstpage();

The context nodes and attributes binded to UI elements in your second page is not getting populated correctly.

Ensure that the context nodes and attributes binded to UI elements in the result view is refreshed based upon entries from first page.

Create supply methods for context nodes binded on seecond page.

Invalidate the nodes on navigation to the second page.
