Searching TREX Index through Web Dynpro

Hi experts,
I'm trying to search through my TREX indexes with Web Dynpro. I have found some sources on this website and they seem to work, but when I test my Application, the table I want to fill stays empty.
The strange thing is that the "getNumberResultKeys()" variable is returning a correct value, but that the "ISearchResultList" stays empty.
I'm a newbie in Web Dynpro, so any help will be appreciated!
I wrote the following code:
     try{
          com.sap.security.api.IUser nwUser = UMFactory.getAuthenticator().getLoggedInUser();
          com.sapportals.portal.security.usermanagement.IUser user;
          user = WPUMFactory.getUserFactory().getEP5User(nwUser);
          ResourceContext resourseContext = new ResourceContext(user);
          IIndexService indexService = (IIndexService)ResourceFactory.getInstance().getServiceFactory().getService ( "IndexmanagementService");
          IFederatedSearch federatedSearch = (IFederatedSearch)indexService.getObjectInstance("federatedSearchInstance");
          List indexlist=indexService.getActiveIndexes();
          SearchQueryListBuilder sqb = new SearchQueryListBuilder();
          sqb.setSearchTerm("SomeSearchTerm");
          IQueryEntryList qel = sqb.buildSearchQueryList();
          ISearchSession session = federatedSearch.searchWithSession(qel, indexlist,resourseContext);
          ISearchResultList results = session.getSearchResults(1, session.getTotalNumberResultKeys());
          ISearchResultListIterator iter = results.listIterator();
          while (iter.hasNext())
          ISearchResult result = iter.next();
          IPrivateDetailView.IPracticeDataElement PracticeData = wdContext.createPracticeDataElement();
                                        PracticeData.setContentSnippet(result.getContentSnippet());
                                        PracticeData.setResource(result.getResource().toString());
                                        wdContext.nodePracticeData().addElement(PracticeData);
     } catch (ResourceException e1) {
                    throw new WDRuntimeException(e1);
     } catch (UserManagementException e2) {
                      throw new WDRuntimeException(e2);
     } catch (WcmException e3) {
                    throw new WDRuntimeException(e3);
Thanks in advance for you help,
Edwin

My context:
value node - PracticeData
value attribute - Resource
value attribute - ContentSnippet
The results are written to the context here (inside the while - statement):
IPrivateDetailView.IPracticeDataElement PracticeData = wdContext.createPracticeDataElement();
                                        PracticeData.setContentSnippet(result.getContentSnippet());
                                        PracticeData.setResource(result.getResource().toString());
                                        wdContext.nodePracticeData().addElement(PracticeData);
I created a table with databinding to the value node (and value attributes).

Problems using Visual Composer with Web Dynpro runtime

I am currently trying to build a Visual Composer iView and we need to use the Web Dynpro runtime rather than Flash because it needs to work with a screen reader for users with sight problems. Which is a pity because Flash works fine. But when I use Web Dynpro runtime I'm getting the following problems:
a) When I define fields and pushbuttons in forms where Align Contents is set to Absolute, they do not appear at runtime in the positions in which I've placed them - all form elements are aligned vertically. The only other options are to align all fields vertically or align all fields horizontally. This lack of flexibility makes it rather difficult to create a good screen design; the only option seems to be to create a separate form for each set of differently aligned fields, which leads on to the next problem. .
b) When I define more than one form on a page, again at runtime the forms do not always appear in the positions in which I've placed them; the compiler seems to calculate how much space it needs to display the screen elements and then re-sizes and re-positions the forms accordingly, ignoring what I've told it to do.
c) Toolbar pushbuttons do not appear on forms (they do appear on tables). Irritating, but at least I can still create pushbuttons on the form itself.
There are other issues, but the main problems is that it appears that when I use VC with Web Dynpro I cannot trust the editor layout at all and the only way I can build something that looks decent is to fiddle about with field / form sizes and positions, checking every change on the output, until hopefully I get it looking ok. Having to do this will dramatically increase the time taken to develop VC applications. Has anyone else experienced these problems with VC and Web Dynpro? Has anyone managed to overcome them?

Thanks, but neither of these describes the problems I've been having. And they are misleading since they say that you can use VC with Web Dynpro only with Web Services ie not directly with BAPIs / RFCs, but using it with BAPIs / RFCs is one of the few things that works well in our system.
The most recent problem I've found is that if you make a form or table read-only it will stay read-only in Flash but the fields are editable in Web Dynpro. The individual field disable option does work for Web Dynpro, but it turns the fields from black to a vey pale and almost invisible grey (this doesn't happen in Flash). And you can't seem to change this.
It does seem to be a bit pathetic that input fields can't be made read only. I've tried expression boxes, which are read-only anyway, but they appear in as pale a grey as the disabled input fields. And although plain text fields can be added to tables, they are pretty useless since they can only hold a single value and so all the lines will contain the same value.
I guess I should resign myself to the fact that I am never going to be able to produce a decent screen using VC and Web Dynprp.

Web Dynpro Field Elements Disabled

Hello:
   The text fields of my Web Dynpro App are disabled when I run the app. Im trying to change the Collection Cardinality in the context to 1...1 but I cant, it seems to be disable too.
   Can anyone help me? How can I change the cardinality?
Best Regards

Hi
You need to add the following code in your WdDoInit()
//create a new model instance
model = new <name_of_your_model>();
//create model objects
<name_of_your_request_model_class>   requestMO = new <name_of_your_request_model_class>(model);
<name_of_your_send_model_class>       sendMO = new <name_of_your_send_model_class>(model);
//associate model objects
requestMO.set< name_of_your_send_model_class>(sendMO);
//bind exacutable model object to context node
wdContext.node<name_of_your_context_node_for_ws>().bind(requestMO);

Events for web dynpro UI elements

Hi,
In NWDS there are only a few event types associated with each UI element type. Say InputField has 'onEvent' event, DropDownList has 'onSelect' etc.
So, for the Input fields are we limited to triggering an event handler to fire only when the user hits the 'ENTER' key? What do I need to do to trigger an event handler for say when the user hits a 'TAB' key ? Is there some way we can extend the event listener interface to add more events to an UI element ?
Please advise. Thanks !
Sri

There is no event triggered when the input field looses focus.
You cannot add your own events.

Web Dynpro UI Elements not appearing in GP

Hi everyone,
I have been developing some Development Components using the GP guide found on SDN. The first CO works just fine but for some reason, the second one I created doesn't show any UI elements and it doesn't return any error messages. Has anyone had this happen to them before?
The difference between this DC and the previous one is that I included a second view and a second window to use as a popup.
Any ideas?
Thank you very much,
Luis

The problem was I didn't include the main view in the WebDynproCO window which is why nothing was being shown.
Problem solved.

Web dynpro UI element visibility

Hi
My situation is this.
I have a view on which I want to display certain fields to the user depending on whether a particular value is present in a database table.
In the Context I have attributes of type WDUI_VISIBILITY which are mapped to the relevant UI elements in the layout that I want to set to visible or not when the view loads.
In the WDDOINIT method I have declared local variables like so: DATA lv_visible TYPE wd_this->element_properties-visible.
I then perform the database check which I can see is fine in debugging and assign values to my local variables:
IF lv_unfal NE 'X'.
       lv_visible = 02.
      lv_hod_visible = 01.
     ELSE.
       lv_visible = 01.
      lv_hod_visible = 02.
And then assign those values to the context element.
     lo_el_properties->set_attribute( name = 'VISIBLE' value = lv_visible ).
    lo_el_properties->set_attribute( name = 'HOD_VISIBLE' value = lv_hod_visible ).
    lo_el_properties->set_attribute( name = 'HOD' value = lv_hod_vis ).
However on loading the view not all of the UI elements are being made visible/invisible as I would expect/hope! I am missing something here? I've used this concept before and it worked ok. Is is something to do with the WDDOINIT method?
As always very grateful for any suggestions.
Thanks
Jon

Hi Rama
Can you elaborate on how by default the the ui elements are not visible please?
I've double checked all the assignments and I have bound the visibility attribute to all required UI element's Visible Property.
There are no other methods with code that is overwriting the INIT method. One of the elements involved is a checkbox which has an onToggle event. I'm not interacting or setting it on loading the view but might that have an effect?
Cheers
Jon

Adobe Library Elements in Web Dynpro

Hi,
I cannot see the Web Dynpro tab elements under the library palette, even though I have defined the check and submit actions for the interactive form.
My NWDS is SP12, and Adobe Reader is 7.0.5. Can anyone point me in the right direction?
Thanks,
Manik

Hi Manik,
Close your NWDS and then open once again. There were some problems like this. When you restart your NWDS such problems disappear.

Load and Display Multiple Images in a Web Dynpro Table

I am new to Web Dynpro and I am wondering if anyone can help me with an application that I am currently developing. I have a particular requirement to store images in a database table (not MIME repository) and then display them in a WD table element. An image can be of JPEG, PNG or TIFF format and is associated with an employee record.
I want to create a view in my application that displays multiple images in a table, one image per row. I want to do this using Web Dynpro for ABAP, not Java. I have looked into pretty much all examples available for Web Dynpro and came to the conclusion that Components such as WDR_TEST_EVENTS and WDR_TEST_UI_ELEMENTS do not have any examples of images being stored in a database table and viewed in/from a Web Dynpro table element. Programs such as RSDEMO_PICTURE_CONTROL, DEMO_PICTURE_CONTROL and SAP_PICTURE_DEMO do not show this either.
The images to be displayed in the Dynpro table are to come from a z-type table, stored in a column of data type XSTRING (RAW STRING). So I would also like to know how to upload these images into this z-type table using ABAP code (not Java).
Your help would be greatly appreciated.
Kenn

Date format problem in web dynpro java

Currently, the date format that gets displayed in our webdynpro java application is MMDDYYYY...i am assuming this is because the web dynpro application has language resource set to en_US as its Current locale in the web dynpro deployed content section. Howver i want it to display as DDMMYYYY. I have changed the default properties in visual admin for web dynpro from en to en_GB however this has no impact what so ever as the current locale is always set to en_US even after the change so am wondering this property is hidden some where else. Now the web dynpro i am talking about is a adobe portal application. Could you give me any pointers as to where else i can look for or how i can change the current locale properly ??
Regards
Kal

The date format in the Web Dynpro Java Application depends upon locale. At runtime WDJ will do the following process to get the current locale for the date format to be determined.
1. First the WDJ Application will check for the locale set for the user in UME.
2. If there is no default locale in UME, then the it will check for the locale in the in the browser which in most cases by default is en-us.
3. If not, then it will check for the sap.systemLocale in the Propertysheet default of Visual Admin
4. If there no locale specified in Visual Admin, itu2019s taken from the WAS JVM

Problems using ALSM_EXCEL_TO_INTERNAL_TABLE in Web Dynpro ABAP

Hello experts, im using the fm ALSM_EXCEL_TO_INTERNAL_TABLE.
When i call this fm from a web dynpro i have a dump that says that cannot import the clipboard.
Any ideas why this is happening?
(The parameter of the function are Ok, becouse if I call the function from SAP/R3 everything work fine)
ThankS!

I didn't mean to imply that there is a Function Module that should work from Web Dynpro. In fact I would be highly suprised if there was one. As already posted in this forum, the only way to get data from the client desktop is with the fileUpload UI element. No function module is going to be able to work with the Web Dynpro UI element.

Web Dynpro Java UI Customization from Portal Using CTRL+Right Click in Prev

Hi Team,
I am able to hide some Web Dynpro UI elements from Portal Content Administration >> Web Dynpro iView >> Preview and by Pressing CTRL+RIGHT CLICK.
Here I need to understand the concept like how things work in this case. If we hide some UI in Web Dynpro Java iView customization will there not be any RFC/BAPI calls associated with that particular UI
For Example: Web Dynpro iView is made up of CompA and CompB and I am going to hide the UI associated with CompA. When I invoke the application will there not be any activity like invoking CompA calling associated RFC/BAPI etc related to CompA
Please help me in understand the concepts and performance implications on this.
Regards
Sudhir

Hi Sudhir
You are quite right to raise this concern
If you start hiding elements you may find a change to functionality
For example - in ESS - if you hide a field that is set to mandatory in the back-end ECC when the user
goes to edit the screen they will not see the field and not maintain the field but they will get an error
"fill in all required fields" - which will completely confuse them as they will have filled in all displayed fields
Also if you hide one field in ESS that is required to populate another field this too many causes inconsistencies or errors
Ideal UI elements to hide are those that have been set to unsued (in the case of ESS in the back-end) and have no dependancies to other fields - however there is no complete list - you must test each scenario to your satisfaction
Best wishes

SP18 effect on Web Dynpro controls?

Hey All,
Does anyone know if SP18 made any changes to any of the Web Dynpro controls? We recently went to SP18 and are now seeing some very odd things happening. Just to narrow down where the problem might be, just wanted to see if there are any known changes to Web Dynpro controls.
Example: Calendar control, if you type in 31/05/07, an error message will be returned in German. When all other error messages are returned in the correct language.
Thanks,
-Kevin

These validation messages are not part of the Web Dynpro UI elements but come from the Java DDIC. So if you find a bug, open an OSS message on BC-DWB-JDD.
