Complete steps of RoadMap UI element in webdynpro

hi all,
     Can some one tell me the complete steps of how to implement RoadMap UI element in webdynpro.
Thanks in advance.

Hi Amol
I need help in implementing RoadMap.
My code is as follows:
  public void onActionStep1(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionStep1(ServerEvent)
final String stepId = wdContext.currentContextElement().getStepSelected();
wdComponentAPI.getMessageManager().reportSuccess("step selected ---> "+wdContext.currentContextElement().getStepSelected());
wdComponentAPI.getMessageManager().reportSuccess("stepId ---> "+stepId);
  if ("Steps1".equals(stepId))
     wdComponentAPI.getMessageManager().reportSuccess("step selected ---> "+stepId);
     wdComponentAPI.getMessageManager().reportSuccess("Welcome to Step 1");
  else if ("Steps2".equals(stepId))
     wdComponentAPI.getMessageManager().reportSuccess("step selected ---> "+stepId);
     wdComponentAPI.getMessageManager().reportSuccess("Welcome to Step 2");
  }else if("Steps3".equals(stepId))
     wdComponentAPI.getMessageManager().reportSuccess("step selected ---> "+stepId);
     wdComponentAPI.getMessageManager().reportSuccess("Welcome to Step 3");
  }else if("Steps4".equals(stepId))
     wdComponentAPI.getMessageManager().reportSuccess("step selected ---> "+stepId);
     wdComponentAPI.getMessageManager().reportSuccess("Welcome to Step 4");
  }else if("Steps5".equals(stepId))
     wdComponentAPI.getMessageManager().reportSuccess("step selected ---> "+stepId);
     wdComponentAPI.getMessageManager().reportSuccess("Welcome to Step 5");
    //@@end
StepSelected is a context attribute of type String.
RoadMap.selectedStep is binded with StepSelected
RoadMap.onSelect event with the action Step1
But i'm not able to display msg on selecting the step.
The above code is from the following link:

  • Cannot click on steps in RoadMap UI Element

    Hello experts,
    Is it possible to select a particular step on the RoadMap UI element, by clicking on it?
    The idea is to be able to click on a step and be able to navigate to the content of that step directly instead of clicking through Prev/Next.
    I do not see an "OnClick" event on a Step wherein I can create a handler. I am on NW 7.0 SPS15
    Regards,
    Puja

    Hi Puja,
    I guess you are takling about the step being highlighted with some different color when the user selects the step . if it is so then there is definatly an option for highliting the step with a color when you click on it .  Let me expalin you a very simple example by which you can understand iit more clearly.
    Step 1. You create a steps for instance (3)(step1, step2, step3). so here when i try clicking it on each step 3 different compeonents needs to be called wiht the step being highlighted.
    Step2:Create a node in the context say Roadmap (0:1) cardinality and attributes as (set_step(property as string) (set_next (wdy_boolean) set_previous (wdy_boolean).
    Step2. In compoent controller of your component create 3 methods hope u are already aware of this.
    set_step( ),  Set_next( ), Set_previous( ). and in attributes of component controller "Navigate" and in importing values giv 'Target'. whcih will capture the the target when we click on the steps.
    Step3: create inbound plugs and method Onselect.
    hope you know the procees to be done futher.
    Note: if you are not able to get the step as highlighted plz chekc  in the method set_step wether the step values are  being passed correctly if no then pass the value of step properly then i am sure that it will higlight the step when u click on it .
    if you want the code for the above senario will surely send it to u .
    GoodLuck!.
    Regards,
    Sana.

  • Personalization of Roadmap steps in Roadmap UI element

    Hi All,
    I want to know of if it is possible to hide/unhide the Raodmap steps in the Roadmap UI element at runtime. When I do ctrl + right click, the entire roadmap is hidden.
    Thanks,
    Pooja

    HI Pooja,
    for personalizing i hope this would help u better :
    Changing the position and visibility of  UI elements – for example, for fields and tables.
    · Adding or changing additional interface information – for example changing the button text or adding quick infos.
    · Role-specific changing of interface labels.
    · UI element roadmap: Removing individual, unneeded process steps.
    · Statically changing individual field attributes.
    · Changing the alignment of individual UI elements – for example, line starting point, align right, centered alignment.
    · Wider selection of fonts and colors for the interface layout
    Hope this might help u.

  • Help about RoadMap UI element

    Hi experts,
    I am new to WDABAP. I followed one tutorial 'Working with Roadmap UI Element in Webdynpro ABAP'. Iam getting the following error while compiling my component.
    "Error in Generated Code: Methos ONACTIONSTEP_SELECT
    The CAST operation (f1 != f2, MOVE f2TO f1) is currently only supported for object references."
    Can any one please suggest me what will be the cause of this error?
    Thanks in advance
    LNarayana

    Hi,
    Please check the ST22 for the detiled error log. I think there is a problem in using the fieldsymbols.
    In your case, i guesss f1 and f2 are field-symbols. first assign the FS to variable then try to move it to other.
    If not, paste the detailed error log.

  • Space between 2 step of roadmap

    I have a roadmap composed by 2 step.
    I nedd insert a space between first and second step of roadmap like in picture
    first roadmap element    second road map element
    Help me please

    marco,
    This is not controllable, so accept defaults
    The only thing that affects space are names uses for step titles/descriptions. So try to create "verbose enough" texts to get additional space.

  • Searching for a UI element in WebDynpro

    Hi guys,
    I would like to have a toolbar like in Service Marketplace when you log a message to SAP. There's the roadmap UI element at the top (Choose system, Prepare solution search...), after there is an horizontal gutter and then there is a toolbar with buttons likes save messages, sent message. The background of the toolbar is blue. How do I create this toolbar. In web dynpro, toolbar can be inserted inside a tray or group but here there is not tray or group UI element. I can create a button row but how to set up the background as blue like the in the toolbar, how do SAP create that?
    Thanks

    I didn't think it was newer functionality, but evidentally it is. I'm running 7.0 EnhP1.  When I right click on ROOTUIELEMENT and choose insert an element, toolbar is one of my options.

  • UI element in Webdynpro to align the content area at the center of the page

    Hi Experts,
    I am looking for a UI element in webdynpro which can keep the entire content area aligned to the center of the page as well as can provide the borders along the content area.
    Please suggest if there exists any such UI element in webdynpro.
    P.S. We are using NWDS Version: 7.01.00
    Thanks in advance for the replies.
    Regards,
    Anurag

    Hi Anurag,
    What you can try is to put all of your UI elements in Group and then do the alignment. Set the visibility property of the group header to invisible. This will give you a border.
    Hope this solves your problem.

  • BPF completed steps doubt

    Hi,
    I am working on BPC 10 NW and i have a doubt about the BPF functionality cause i have created a BPF template with several steps and every step has some hyperlinks. My doubt is: I supose the BPF should block the hyperlinks inside a step after it is closed but it is not doing it, when i set the step as closed its working only as a mark but the hyperlinks are still available for the owner. Is that the right behavior?, if so, how can i manage to block the user for example from loading data after the loading step is completed. I spect the BPF to block the hyperlinks on a completed step until it is re opened. Any help would be apreciated.
    Thanks in advance.
    Pedro Santiesteban

    Hi Michelle,
    After not getting any response on the forums we asked SAP directly and the answer was that the completed steps were not designed to be locked on BPC 10. The great news is that on SAP BPC NW SP08 they released an enhancement implementing this feature. Please check the note 1741090.
    You should also check note 1703032 it is the central note of the SP08 release and it has several enhancements.
    Hope it helps.
    Regards, have a nice day!

  • Could not complete your request because Photoshop Elements cannot recognize the file extension. (-25600)

    im trying to add a water mark to multiple photos but I keep getting  Could not complete your request because Photoshop Elements cannot recognize the file extension. (-25600) error. how do I fix this?

    If you open up editor then expert mode then you click file and the it's manage multiple or something like that. It will pull up a box asking you where you would like to get the photos from. I picked a folder where I just edited the skin tone and then saved it. I'm thinking it has something to do with the way the files save but I'm not sure how to get it to change. But after the box comes up you can add a water mark to all the photos in the folder. I found the video of how to do it on here.
