Want to read Field value set by Value help

Hello,
I have BSP View which is using Value help extensions for one of the input. The search help is based on the Elementary Search Help which is further based on Z-Table. In my BSP view [IE] I am able to popup the Search help and able to select the Value from list of choice. The selected value gets reflected in the Input field of browser. The problem is I am not able to capture the selected value in Event handler. I need to capture this value and get the related data in other input fields [which are display only]. How to do this?
I even tried getting the value in the Javascript, but unable to assign the Javascript variable to my BSP View attribute or Controller attribute.
Thanks in advance.

>Do I have to trap it in DO_HANDLE_Event by doing Get_Form_Fields??
If you are using MVC and data binding you don't have to do anything. The field values will be brought in automatically for you.
However in any MVC application, the highest level controller should always contain a small block of code in the redefinition of the DO_REQUEST method. It is:
if input is available, dispatch this input to subcomponent.
* this call is only necessary for toplevel controllers.
* ( if this is not a toplevel controller or no input is present,
* this call returns without any action)
dispatch_input( ).
* if any of the controllers has requested a navigation,
* do not try to display, but leave current processing
IF is_navigation_requested( ) IS NOT INITIAL.
RETURN.
ENDIF.
This code is critical for properly dispatching events through the controllers. It is also the code that triggers the MVC runtime to restore input values into the model.
Also to eliminate the possibility with a problem in the implementation of the value help, why don't you temporarily switch out this element with just a plain htmlb:inputField. This way you test to make sure that data binding works correctly with the standard field.

How to develop ALV and select-option element in BSP? Help!

Hi Experts,
I have a requirement where I have a selection screen with 3 select-option elements and a search button. On clicking the search button an ALV table report has to be shown.
The ALV table is used for new row/rows entry, delete row/rows and update row/rows data. This is something like table control in normal ABAP.
Additionaly, I want the download to Excel, sorting, filtering, column swapping options in ALV.
How can I achieve this in BSP?
Is there any existing SElect-option and ALV component in BSP?
Any code sample will be really helpfull.
How much development time will it take?
Please help!
Thanks
Gopal

I think you will find that most of what you are looking for does NOT exist out of the box for BSP. There is no delivered selection-option or value help. I ended up creating my own over the years (You can find some versions online here in SDN in my weblogs - however a complete implementation of select-options was only delivered along with the Advanced BSP Programming book).
There is no ALV either. However with the htmlb:tableView, you can acomplish quite a bit. You may have to learn about table view iterators to get it all done. Downloading to Excel also isn't delivered. I developed a reusable BSP Extension element for this as well (can be found on SDN in my weblogs or with the Advanced BSP Programming book).
If you plan to recreate all these elements by yourself, your project will take some time. It took a while to build so many complex UI elements.
What release are you running on? In Netweaver04S you have Web Dynpro ABAP. WDA has delivered components for value help, select-options, and ALV.

BSP: F4 Help For a custom field...

Hi All,
I need to display search help for a custom field in one of my custom view.
Search Help for the custom field is already implemented.. but how can i use it in BSP View!.
In the standard CRM_IC application i couldn't find any similar search help scenario, coz it is calling some standard methods like ShowF4KeyAndValueHelp3,
ICWCShowF4HelpExtern by passing the structure and field name!.
I think these standard methods will work only with the fields which have value help table at the data element level. As the custom field that i m using does not have any value help i cant go for this method i guess!.
Any Help/Hint?..
Thank You,
sudeep v d.

Problems with F4 Value Help in NW2004s Portal

Hello,
we are having some troubles with the F4 ValueHelp Extension from the Advanced BSP Programming book (and the blogs of course).
We've implemented the solution on a 4.7 backend and portal 6.0. No problems there, everything was working fine.
We now moved to erp2005 (WebAS 700) and NW2004s Portal (7.0).
The popup shows and I can select entries from the list. But when clicking the ok icon a javascript error is thrown stating that 'parent.document.getElementById(...)' is null or no object.
I think the problem is, that by making a call to 'parent' we are searching in the portal frame and not the BSP. There (in the portal frame) the element is not known so the error is thrown.
I allready changed from the dialog_ie6.js provided on the BookCD to the one delivered by SAP. Did nothing regarding the error.
I also tried changing ZCL_BSP_M_INPUT_HELP->BUILD_ACCEPT_SELECTION_SCRIPT. I changed all the "parent.document.get..." "to document.get...". The error message was still the same, 'parent.document.getElementById(...)' is null or no object.
So now I'm kind of stuck. If I try the example outside the portal everything works as expected. So this clearly seems to be a problem with the portal integration. All involved BSP-Apps are marked as "supports portal integration".
Any ideas on this topic?
Thanks and kind regards,
Alexander Sperling

I have a working solution to the problem. It isn't the nicest solution because it will probably require some modifications to the application that hosts the value help, but we will get to that in a second.
I tried many different ways to come up with a solution that would still work via JavaScript. The portal is now loading the popup javascript in the master frame. It registers event handlers so that if any application triggers a popup internally it "hi-jacks" the event. So regardless of what I change in the BSP javascript library, it gets overriden by the portal one. The portal also now even enforeces its theme on the inner page in the popup. Truly the portal takes complete control over the inner html of the popup.
To make things worse the popop has not path to reach the source that triggered it. The source objects are tracked in the javascript, but because the master frame takes over; the popup window only has access and visibility to the master frame and the navigation frame. In essence in the DOM it is now higher in the stack than the object that actually triggered it.
Web Dynpro gets around this because it doesn't use any client side mechanisms to communicate it results back to the source frame. Web Dynpro has the luxury of always being stateful and therefore can make certain assumptions that would never work in BSP. The hi-jacking is an excellent solution for Web Dynpro. The portal can then override the functionality of Web Dynpro - providing the new functionality of floating the dialog box over the entire portal - without having to make any changes to the Web Dynpro Framework. However they never had our little BSP solution in bind obviously.
It might be possible to completely rewrite the popup_ie.js and popup_ns.js to use all different event, method and variable names. This separate version could then provide complete separation from the portal script. However this is just a theory. I'm afraid that I wouldn't have the bandwidth to rewrite the entire script right now so I focused on a quicker solution.
The only approach that I could come up was to follow the Web Dynpro approach and return to the server with the value. To do that I used Portal Eventing. Portal Eventing allows us to pass a value to the source frame regaurdless of our relative positions in the DOM.
In my inner BSP application for the value help (ZES_VALUEHELP), I made the following change in the model method BUILD_ACCEPT_SEL_SCRIPT_V2. At line 141 I changed the logic. Instead of using JavaScript to write the selected value back into the source element, we will just trigger a Portal Event:
****With an InputField we write the contents directly back into the element
 ELSE.
 CONCATENATE me->js_close1
 `portalFireEvent('com.sap','`
 me->element_id
 `',"`
 key
 `");`
 INTO me->js_close1.
 EXIT.
The other change is within the Element handler class for inputHelpV2 - ZCL_ES_BSP_ELMNT_INPUT_HELP_V2. We need to register the listener for the Portal Event. Therefore in DO_AT_BEGINNING we will add the follwing at line 23 (right after we place the Element Id into the URL Parameters Table.
data: portal_event type ref to cl_portal_event.
portal_event = cl_portal_event=>factory(
 name = <wa_params>-value
 namespace = 'com.sap' ).
while m_page_context->element_process( element = portal_event ) = co_element_continue.
endwhile. "End portalEvent Render
Overally using the portal eventing actually is an intersting approach. There is only one drawback, now we have a server side event. That being the case, our application now needs some event logic to process this event and populate the value. Depending upon if you are using MVC, Data Binding, or Flow Logic this could vary - and would have to handled by each application. The nice thing about the old approach was that it all happened via JavaScript on the Frontend and didn't require the application programmer to do anything - that was obviously its weakness as well.

Value help in freestyle

Hi,
I am trying to do value help in free style mode.
I am using the following tag.
<THTMLB:INPUTFIELD tag
id =
helpinputfield =
helpoutput vield=
value=
Markup/Result
Please telll me what should I provide for value?
Why sould we give in this format
value\struct.product ? whats its significance?
regards,
CMP
Edited by: Muralidhar Chatna on Oct 7, 2010 8:33 AM

Hi,
value defines the actual displayed field value, so you either need to define the binding to a context node, assign a value or retrieve any value by your ABAP code on the BSP layout.

Custom Error Message in Value Help

Hi,
In my application i have a Inputfield called "CLASS", for which i have added a value help..it has these values
B Business
E Economy
F First Class
When the user enters a value(say "X") other than B, E, and F, it displays a message
String "X" does not match the enumeration
I want to put my own message like " Please enter a valid value" instead of the above message.
Please let me know how to do this ?
Thanks
Senthil

Senthil,
First, "looping through the list and checking the user entered value with values in the list" is possible only with non-validating actions. Using non-validating actions is a tricky task in real life.
Second, workarounds are possible, but they involves calculated attributes (like here: /people/valery.silaev/blog/2005/11/29/800format-your-way). Solving this problem generically (45 attributes is a good number to start with a generic solution) will result in solution with complexity comparable to this: https://weblogs.sdn.sap.com/pub/wlg/3309.

How do you use user defined error messages in Value Help?

Hi,
I'm currently working on a Modifiable Value Help Selector in Web Dynpro Java, and I want to use a user defined error message when I validate the values entered by a user. Currently, it's returning its default error message ("Character <string> does not match...").
Since the project requires a different error message, is there a way to override the default error message and use my defined error message instead?
Thanks!

Hi Angelo,
I am not sure why message area is showing both Custom and inbuilt messages but you can try the following:
i guess you must be using reportContextAttribute exception for showing Error messages on the input fields as well.in that case you can disable the message area so messages will appear only on the Context level ie; on input fields.
For other messages apart from validation messages you can enable the message area before reporting the exception.
make sure the boolean context variable which will be used for enabling and disabling the message area should have Readonly property set as true.
I am not sure whether this is the only solution for this but you can try and see if it works.

Hide Toolbar and Value help drop downlist

Hi,
I created a IF with a Value help drop down list. I also make use of the Hide Toolbar options. The drop down list has an input like:
key - text (eg. 0001 - Holiday)
The pdfMode is "UpdateDataInPdf".
When i run my wd everything works fine. What i want to do is this: when the user push the button "next" i want to show the IF in a read-only mode. What i did, is that when the user push to button i change the PdfMode from "UpdateDateInPdf" to "GeneratePdf" (also tried "UsePdf") and change the "enabled" property to false.
What happens is, the Adobe toolbar is back and the value help dorp downlist shows the key instead of the text.
If i don't change the "enabled" property it works well, but than it's still possible to change data in the form.
I am using NW04 SP16.
Hope somebody can helps me.
Kind regards,
Maarten Duits

Hi Maarten
in general, right now there is no standard (i.e. non-hack) way to make a physical interactive PDF form read-only.
The only sure way this would work in your process is to send the data back to the backend and have a second (practically identical) template ready in the background to generate a read-only version of what the user saw previously.

Selection Screen - Text instead of Key in the value help

Hi ,
I have implemented selection options for Web dynpro.
The value help for the selection fields displays the key of the selected value (standard).
I would like to know if there is an option to display the text (instead of the key) in the field.
Key Text
01    AAAA
02    BBBB
03   CCCC
So if I select say - 01 and 03 in the value help, Can I display AAA, CCCC in the field (or next to the field)
Thanks,
Sri

Date format is not working properly for Calender value help

Hi Experts,
We have two problems.
1. We want to change the format of date displayed. We want format of dd-MMM-yy. For that we have created one Simple
Type Dictionary Object with Displaying format dd-MMM-yy. It is working
fine for the non editable UI. But once I apply the dictionary type
object as data type for an input field, probem happens. Once the user
choose a date from calender value help the value in the input field is
coming like 01-011-12 not like 01-Jan-12.
The date format is not changing from the calender. But if we set the
display format of the dictionary object to MM-dd-yy or MM/dd/yy or
dd/MM/yy or dd-MM-yy the format conversion from calender to input field
is happening properly.
The only problem once we put MMM in place of MM for the input field
where user is selecting from a calender value help.
2. We want to restrict users from entering the value manually for date input field. The user
should be able only to enter value by selecting from calender value
help.
Please give suitable solution for these problems
Thanks

Some fields from R/3 have automatic value help for input field on WD

Hello,
we have imported a Model from RFC/JCo (ABAP) with several fields. One of them is "IWAER" of SimpleType Iwaer and "Built-In-Type" string in J2EE. Though the enumeration of this type is empty, WebDynpro mystically generates a value help if the type is assignet to an ImputField. On the ABAP-side component type is IWAER with data type CUKY and in domain WAERS which has a value table TCURC (instead of fixed values in a value range).
Where/why does WD find out that this is a currency-field and where do the values in the value selector come from?
Best regards,
Manuel

Hi,
at least for the ModelData-Connection (BAPI-Call) there is no data being transferred besides one value for each field.
I don't know if the MetaData-Connection of JCo is able to get more information (e.g. key-value-pairs for the domain or type the field belongs to,..) than just the structure of the interface.
-> Where and how do these EVS-values come from without doing something?
Best regards,
Manuel

Visual Composer 7.0.1 (EHP1) - Value Help only shows "Single Selection"

I tried to add a value help to a field that allows multiple selections. However, when I used the wizard through "Add Value Help" drop-down menu, I can only see one proposed selection - "Single selection". However this SAP help document (http://help.sap.com/saphelp_nw70/helpdata/en/b5/036d391f074f769e00602634ee9960/content.htm) mentioned about the "Multiple selection" option. What I can do to make this selection available?
I am using VC 7.0.1 (EHP1). Thanks for any helps in advance.
Kelly

Hi
Are you using 'BI Query' as 'data Service'? & are you creating value help for variable? If Yes -
Create necessary variable as 'Multiple Single Options' in your BEx query & then create value help in VC. Then it will allow multiple options or interval values.
