Two Buttons with same Method Invoked = ShowPopup, displaying different popup applets!!

After reading the title of this post, you might have got some idea what the scenario I am going to talk about today. This is the scenario where I have two buttons exposed on the UI and both having the same Method Invoked = "ShowPopup".

Here below is the snapshot:

1.      Create SR        :           this button is being used for displaying “Create SR Popup Applet”.

2.   Create Order  :           this button is being used for displaying “Create Order Popup Applet”.

For configuring this simple requirement, you can have the following configuration:

“Create SR” Button	“Create Order” Button
Method Invoked = ShowPopup Control User Properties o   Popup = Create SR Popup Applet o   Mode = Edit	Method Invoked = ShowPopup Control User Properties o   Popup = Create Order Popup Applet o   Mode = Edit

No Issue till now. This pretty simple configuration would work fine!

But the problem comes in when there is a need to execute few lines of server script when each button is clicked, something like:

            If “Create SR” button clicked then

                        Set the Profile Attribute “NewEntityCreated” to “Service Request”

                        Call the web service “X” to retrieve some values from other system.

                        After that display the popup applet : “Create SR Popup Applet”

            If “Create Order” button clicked then

                        Set the Profile Attribute “NewEntityCreated” to “Order Entry - Orders”

                        Call the web service “Y” to retrieve some values from other system.

                        After that display the popup applet : “Create Order Popup Applet”

So, now the problem is, both button clicked will invoke the method “ShowPopup” and there is no way to identify which button is actually clicked.

Solution:

To overcome this, we have to have the different “Method Invoked” on each button.

1.      Instead of using “ShowPopup”, invoke the custom method for each button i.e.

a.      Method Invoke for “Create SR” button would be “CreateSR”.

b.      Method Invoke for “Create Order” button would be “CreateOrder”.

2.       Put the server script in PreInvokeMethod of the applet:

if(MethodName == "CreateSR")

            {

TheApplication().SetProfileAttr(“NewEntityCreated”, “Service Request”);

//         Code for calling the Web Service X

//         ……………………………………………………

//         ……………………………………………………

PopupApplet(“Create SR Popup Applet”);

                        return (CancelOperation);

            }

            if(MethodName == "CreateOrder")

            {

TheApplication().SetProfileAttr(“NewEntityCreated”, “Order Entry - Orders”);

//         Code for calling the Web Service Y

//         ……………………………………………………

//         ……………………………………………………

PopupApplet(“Create Order Popup Applet”);

                        return (CancelOperation);

            }

3.      Create a new Function as per below script:

function PopupApplet(strAppletName)

{

var oBSSLM = TheApplication().GetService("SLM Save List Service");

var psInp = TheApplication().NewPropertySet();

var psOut = TheApplication().NewPropertySet();

psInp.SetProperty("Applet Height", "400");

psInp.SetProperty("Applet Mode", "2");                          

psInp.SetProperty("Applet Name", strAppletName);

psInp.SetProperty("Applet Width", "800");

oBSSLM.InvokeMethod("LoadPopupApplet", psInp , psOut);

            }

Limitation of “SLM Save List Service” business service

If there is a requirement to display another popup applet from a button click on a Popup applet, then this business service doesn’t work and you might see the error:

View: <?> does not contain applet: <?>.(SBL-UIF-00401)

So, in this case the only choice is to either use “ShowPopup” method or if you can’t use it because of the scenario explained above (having two buttons with same Method Invoke i.e. ShowPopup) then other option is to use hijack the custom method invoked and invoke the Browser Script (for displaying popup applet) as explained here in earlier post.
