Hi,
Follow the below steps:
1) Go to the page HelloWroldPG from front end, click on 'Personalize this page' link.
2) Check that on which region HellowWorldMainCO is attached.
3) For example, if it is attached on pageLayout region, click on Personalize pencil icon.
4) on 'Controller Class' property, set the complete path of your custom controller in place of 'inherit' (at whatever level u want like site or resp)
5) Click on apply.
Now you can see your changes.

  • How to extend the seeded controller?

    Our requirement is to insert warning messages in seeded HR Self Service transactions. On click of the next button, we need to evaluate conditions depending on the values filled in by user and throw warning dialog page with
    with ok button on it. When user clicks OK on the warning window, next page should be displayed.
    So the need is to insert warning dialog page between navigation of 2 pages.
    Is this possible to do in a Oracle seeded transaction. I believe I would
    need to extend the controller of the page and insert my code in the controller.
    Has anyone dealt with such a scenario before , how do it achieve it and How a controller can be extended?
    Thanks,
    Tanveer

    This definitely is possible. You will have to extend the seeded controller and override the seeded behavior for this particular scenario. After your logic ends, call the seeded code which will handle the rest.
    For getting started, look at dev guide and other similar discussions.

    How to extend the range with a second Airport Express? Do I need a DSL cable?

    Thanks, now we need a bit more information, please, in order to provide you with the correct information that you need.
    I assume that you already have one AirPort Express.....either a model A1264 or A1392.....set up and operating OK, is that correct?
    If yes, you can extend the network either by using wireless or an Ethernet cable with a second AirPort Express.....either the A1264 or A1392 model. A wired connection is the way to go, if possible, since it provides better performance.  But, wireless might work OK for you if you want to try that.
    Let us know "how" you want to extend......wireless or wired?

  • How to extend the size of a layer?

    Hi all,
    Hopefully this is an easy one, but I think I'm just thinking about it wrong.  I'm animating the movement of one part of a photo.  I duped the photo layer, masked out the subject I want on the copy layer and have animated its position over time.  Pretty straight forward.  The problem is that as the item moves its edges are seen.  I wanted to just use the clone stamp to add a little more to the image but obviously you can't paint or stamp past the edge of the layer.  So I was trying to figure out how to 'extend' the bounds of the layer a little so that I can fill in the missing area.
    Thanks for any input.
    -Chris

    Hi Todd,
    Thanks for the reply.  Unfortunately, I'm not having any success with this method.  Here's what I have:
    Original photo of kids with ball at playground.  Ball is at lower left but partially cut off. Photo is on layer 1.
    I duplicate layer 1.
    Rename layer 2 to 'ball' and layer 1 to 'bg'
    On ball layer I mask out the ball and then animate its position over the length of the clip.
    When I precompose the ball layer (I tried both moving the attributes and leaving them as is) I get the new composition 'ball comp 1'.  I open up ball comp 1 and change the composition settings to make the width taller.
    So far, so good.  Now I'm trying to follow your suggestion to then paint on the precomposition layer.  Do you mean to go back to the original composition where the new pre-comp layer is and try to paint on it?  If so, that doesn't work.  If I select the Clone tool and try to paint the layer actually gets moved rather than painted on.  If I open the new 'ball comp 1' composition and try to paint there it doesn't work either. And if I open up the layer in that comp that has the ball in it and try to paint there, the edges are still the original edges. 
    Any idea where I went wrong?
    THanks,
    Chris

  • How to extend the range of my Airport Extreme network by adding an Airport Express

    How to extend the range of my Airport Extreme network by adding an Airport Express?

    You have to make sure that the AirPort Express is in Factory Default Settings. If it is straight out of the box, it is ready to be configured.
    The instructions that I will provide are for using AirPort Utility 6.0, which you have.
    Locate the Express in the same room as the AirPort Extreme for the configuration. Power it up and allow a full minute for the Express to display a blinking amber light.
    Make sure that the wireless is turned on your Mac
    Open AirPort Utility 6.0 and look at the small rectangle in the upper left hand corner of the display. It should now read something like "Other AirPort Base Stations (1)"
    Click on the rectangle, and then click on the AirPort Express xxxxxx listing
    AirPort Utility will take a minute or two to analyze the settings on your network and then suggest that  the Express be configured to "Extend" your wireless network.
    Edit the Base Station name to your liking, then click Next in the lower right hand corner
    Allow a full minute or two let AirPort Utility do its work
    When you see Setup Complete, click Done at the lower right of the window.
    Now move the AirPort Express to a location that is approximately half way between the AirPort Extreme and the area that needs more wireless coverage.
    You should be in business.

  • How to extend the WebUI product search results with customer attributes

    Hello,
    We are using CRM 7.0. We want to extend the WebUI product (Object) searches with customer attributes and to display customer attributes in the search results. We found the note 1026956 that explains how to extend the WebUI product (Object) searches with customer attributes. We want to know if there is also some note that explains how to display customer attributes in the search results for products/Objects.
    Thanks in advance,
    Sergey Kozyrev

    Sergey,
    I doubt whether there exists such note. The note 1026956 which you mentioned is for enhancing the Search for Custom attributes. For Enhancing the Result list you need to do custom development.
