Hi Experts,

Hi Tashi,

This can be done by using work protect mode in WDA

Please refer the below documents

Work Protect Mode (SAP Library - Web Dynpro for ABAP)

Also, search in Google by term "work protect mode in webdynpro abap", you may find some examples.

Hope this helps you.

Hi Rama,

     How are you !! i included the code in the init method of component controller,but i dont get any warning message when i click on refresh or back button.

Please help

Hi,

It(the mentioned SAP Help) works if your WDA application integrated in Portal. If you are using FPM, you can use IF_FPM_WORK_PROTECTION interface to achieve this.

Hi Tashi,

I am doing great Hope the same from your end.

As suggested by Mr. Kiran, the work protect mode works when we integrate our applications in enterprise portal.

my application is a standalone webdynpro applicaiton, my client requires me to give a warning message when user click "back/forward/refresh" button on the browser. if this cant be done through work protect mode, is there any other way of achieving this.

Thanks & Regards,

Hi,

No. As mentioned in my earlier reply, either you have to Integrate your Application in Portal or use FPM where there is a provision to set work protect using IF_FPM_WORK_PROTECTION interface.

so there is no other way than the "work protect mode" concept. i am thinking if we could catch the browser events in applicaiton and execute a message for the same. will that be possible , if so, how ?

Thanks & Regards,

Hi Katrice,

     I checked your thread and its definitely the same end solution i want to implement.However i am not sure how to use this interface.

i have implemented it in my component and i saw a method is_dirty added into the controller.

But from here onwards.. i dont know how to set the dirty flag and how the whole implementation is done. I will really appreciate if you can help me out on the implementation part (sample code will be very useful).

Thanks & Regards,

Hi Katrice,

     i have used this code in view init method:

data L_COMPONENTCONTROLLER type ref to IG_COMPONENTCONTROLLER .

data L_API_COMPONENTCONTROLLER type ref to IF_WD_COMPONENT.
data L_PORTAL_MANAGER type ref to IF_WD_PORTAL_INTEGRATION.

L_COMPONENTCONTROLLER =   WD_THIS->GET_COMPONENTCONTROLLER_CTR( ).

L_API_COMPONENTCONTROLLER = L_COMPONENTCONTROLLER->WD_GET_API( ).

L_PORTAL_MANAGER = L_API_COMPONENTCONTROLLER->GET_PORTAL_MANAGER( ).

call method L_PORTAL_MANAGER->SET_WORK_PROTECT_MODE

  exporting

    MODE   =  'BOTH'  .

then i have a button to make data dirty (button for trial sake) and i have included this code.

data L_COMPONENTCONTROLLER type ref to IG_COMPONENTCONTROLLER .

data L_API_COMPONENTCONTROLLER type ref to IF_WD_COMPONENT.

data L_PORTAL_MANAGER type ref to IF_WD_PORTAL_INTEGRATION.

L_COMPONENTCONTROLLER =   WD_THIS->GET_COMPONENTCONTROLLER_CTR( ).

L_API_COMPONENTCONTROLLER = L_COMPONENTCONTROLLER->WD_GET_API( ).

L_PORTAL_MANAGER = L_API_COMPONENTCONTROLLER->GET_PORTAL_MANAGER( ).

call method L_PORTAL_MANAGER->SET_APPLICATION_DIRTY_FLAG

  exporting

    DIRTY_FLAG = abap_true .

i have included the code in your thread for method need_confirmation generated by implementing IF_FPM_UI_BUILDING_BLOCK.

CASE io_event->mv_event_id.

     WHEN 'FPM_CLOSE'. "
        eo_confirmation_request = cl_fpm_confirmation_request=>go_data_loss.

   ENDCASE.

Please help.

Hi,

     The applicaiton i am working on is a stand alone webdynpro application. Its not implemented in portal.

i wanted to know if FPM alone with webdynpro, i will be able to achieve the "work protect" functionality.

Hi,

Following is the code which i've written for dataloss popup.

Thanks

[former_member193460]

Hi Katrice,

     Thanks for your reply. i have the same code in my method but still i am not getting any pop up.

Are you closing the browser with browser close

i have used fpm type OIF. Please let me know if you have done anything different.

Hi,

You cannot control the close functionality by using because these buttons are browser buttons and you cannot have control on that buttons. Instead, you can give one FPM button by name Close in FPM Toolbar with event id and on click of that button, write the code which i've shown in my earlier post.

Thanks

Hi Katrice,

     i am getting the pop up by using the buttons in the applicaiton, however i want to clarify the following doubts i have:

1) Is it possible to catch browser button events in webdynpro applicaiton

2) i cant see "Close" button in the tool bar element, though i can rename the buttons but i cant change the event ID.

Please help me understand .

Your help is always appreciated !

Hi Tashi,

AFAIK

1) we cannot catch browser button events in wdp appln.

2) In configuration editor, in global tool bar schema->insert tool bar element of type button with event id as shown below

Thanks

Hi Katrice,

     Thanks for all your help. i am not getting the close button probably becoz of the system version.

User had requested to handle the browser events, so it looks like i have to tell them its not possible.

Thanks for all your hlep again.

Hi,

Choose other function button and rename that button name to close.

Thanks

[former_member193460]

how do i change the event ID ?

[Former Member]

When you add toolbar element, its FPM Event ID = EVENT_ID, just rename it as FPM Event ID field is an input field, you can give your own event id else you can choose it from F4 help.

Thanks

KH

[former_member193460]

i dont see any column for Event_ID. Following are the options i see.

i dont see the column for event_id to change it.

Hi Tashi,

Is you issue resolved?

Hi KH,

     i wanted a solution to handle browser events (browser close, refresh buttons), but it looks like FPM can handle only the FPM toolbar events. However i thank you for your help.
