How to handle htmlb:inputField submitOnEnter

Hi Friends,
Iam using submitOnEnter = "true" in <htmlb:inputField> so that when I press enter in that input field some action should take place.
But Iam not sure how to handle that event.
When I use this it is giving page error.
Can anyone help me out how to handle this...
Regards,
Raju...

if you set submitOnEnter = "true" for an inputfield, pressing enter key when the cursor is in that inputfield would trigger server event.
in the oninputprocessing you can capture the event.
also please be aware that submitonenter doesnt work in some SPs as per this thread
htmlb:submitOnEnter at inputField
to capture the value of the inputfield in oninputprocessing you can write the following code
ATA: data TYPE REF TO cl_htmlb_inputfield.
data ?= cl_htmlb_manager=>get_data( request      = runtime->server->request
                                     name         = 'inputField'
                                     id           = 'IP1'
IF data IS NOT INITIAL.
<variable> = data->value .
endif .

How to fire an onblur event for htmlb:inputfield ?

Hi All,
I have a problem in creating in ONBLUR..for input field.
What i want is when i give input to the input it goes to DB and retriving some data and visible to next Dropdown.
For this if i give input to input field and press any key then it will goes to db and getting data.
I am stricking over here .
Please guide me for this.
Thanks
Nageswara.

so what you need is a javscript function to get triggered onblur event and it should generate server event.
check out the following code sample.
<htmlb:inputField id         = "test"
                        alignment = "LEFT"
                        size       = "10"
                        type       = "STRING" />
      <bsp:htmlbEvent id      = "myid"
                      onClick = "myonclick"
                      name    = "ValueChanged" />
        <script for="test" event=onblur type="text/javascript">
      ValueChanged();
      </SCRIPT>

Javascript in the htmlb:inputField

Here is the brief description of the problem:
I have a table view in which i display the htmlb:inputField which are created in the iterator. I need to capture the ENTER Key event and set the focus to the next field in the next row.
I have seen examples of the normal input field but couldnn't somehow figure out a way to do it in the htmlb:inputField. Here is the sample code which i tried to play around with (for normal input fields.)..
<i>function enter(nextfield) {
if(window.event && window.event.keyCode == 13) {
nextfield.focus();
return false; }
else
return true; }
</script>
Field 1: <input type="text" name="field1"
onkeypress="return enter(document.demo.field2)"><br>
Field 2: <input type="text" name="field2" onkeypress="return enter(document.demo.field1)"><br></i>
<b>How do i use this code in the iterator for my htmlb:inputField ? i did try the following attributes
1) submitOnEnter
2) onValueHelp
3) doValidate
but none on them could help me..
</b>..
Any help would be appriciated.

How to handle type safety when using com.sap.typeservices.IProposalList

Hi,
I have been testing out the new features in Web Dynpro Java CE EHP1 using a scenario with BPM and SAP MDM. One of the new features I tested is the Ajax feature of using suggestion values. I have an InputField UI element which have bound to a context attribute (CountriesView/Country) which is of type string. The UI element has the "suggestValues" value set to true. I then use the IProposalList to produce a valueset. This will make the InputField UI appear as a combo box and allow the users to type in a few characters and utilize the Ajax framework to automatically search in the list of values.
The following code works perfectly ok but I don't understand how I should handle the compiler warning "IProposalList is a raw type. References to generic type IProposalList<T> should be parameterized"?
IProposalList proposalsCountry = wdContext.nodeCountriesView().getNodeInfo().getAttribute(IPrivateComp1.ICountriesViewElement.COUNTRY).getModifiableSimpleType().getSVServices().getProposals();
for(int i=0;i<bua.length;i++){
    IPrivateComp1.ICountriesViewElement buaelement=wdContext.createCountriesViewElement();
    buaelement.setCountry(bua<i>[0]);
    buaelement.setCode(bua<i>[1]);
    bualist.add(buaelement);
    proposalsCountry.add(bua<i>[0]);
wdContext.nodeCountriesView().bind(bualist);
I don't have any issues handling this for other types such as ArrayList. Using the syntax "IProposalList<String> proposalsCountry ...." will handle the "proposalsCountry.add .." part but I still have a warning "Type safety: The expression of type IProposalList needs unchecked conversion to conform to IProposalList<String>"
Any ideas on how to handle this?
Thanks,
Johan

Hi,
Eventhough there are no replies to this thread I thought I should update with what I belive is an answer to my question. Excerpt from http://stackoverflow.com/questions/382/what-is-the-meaning-of-the-type-safety-warning-in-certain-java-generics-casts:
"This warning is there because Java is not actually storing type information at runtime in an object that uses generics. Thus, if 'object' is actually a List<String>, there will be no ClassCastException at runtime except until an item is accessed from the list that doesn't match the generic type defined in the variable. This can cause further complications if items are added to the list with this incorrect generic type information. Any code still holding a reference to the list but with the correct generic type information will now have an inconsistent list. To remove the warning, try:
List<?> list = (List<?>) object;However, note that you will not be able to use certain methods such as add because the compiler doesn't know if you are trying to add an object of incorrect type. The above will work in a lot of situations, but if you have to use add or some similarly restricted method, you will just have to suffer the yellow underline in Eclipse (or a SuppressWarning annotation)."
The last line explain the reason for my issue and the lack of a solution when using add method.

Htmlb:inputField always uses encode="TRUE"

Hi,
I have a inputField using data binding. The model field contains "Česká republika", and this code

How can I prevent this HTML-encoding?

Hmm, I don't understand all this.
Look here, this is my complete output (sorry about that) of your example.
And you can see, the ampersand is encoded, but I want the letter È (a upper sized C with a ^ on top).
Why does it work at your place?

Htmlb - inputField color

Hi,
Does anyone know, how to change the default white background color of the inputField in htmlb?

Hi,
I could do it only with java script.
<script language="JavaScript">
       function set_textcolor(name, col)
        document.getElementById(name).style.color = col; "textcolor
         document.getElementById(name).style.backgroundColor = col;
</script>
if you want to change the field static you can do that in following way:
<htmlb:inputField id       = "IN_SCAN_NR"
                  value    = "xxx" />
<script language="JavaScript">
set_textcolor("IN_SCAN_NR","red");
</script>
for dynamic change I did following:
Table it_fields contains IDs of fields I wanted ot set to red color (filled by an check routine).
<%
data:
lv_script type string,
lv_string type string.
loop at it_fields into lv_string.
concatenate
    lv_script
    'set_textcolor("'
    lv_string
    '","red");'
    into lv_script.
endloop.
concatenate
lv_script
'</script>'
into lv_script.
%>
<%= lv_script %>     *** put scripting to html coding
I hope that helps,
sincerely yours .

Need help with htmlb:inputField and Currency format

Hi all,
i'm looking in vain for the possibility to prepare a field with currency.
I have a local field in which an amount is available.
Unfortunately, the amount is spent but not formatted for currency.
current layout: 123456.78
requestet layout: 123.456,78
How do I get through it?
Here is my code:
DATA: ld_betrag         TYPE ZBETR.
definition: the domain of "ZBETR" = 'WRTV7'
LOOP AT.....
ADD wa-betrag TO ld_betrag.
ENDLOOP.
The amount will be added in a loop.
<htmlb:inputField id = "betrag"
            disabled = "TRUE"
            value    = "<%= ld_betrag %>" />
Output is via a htmlb:inputField
I have the same definition for a amount field in a htmlb:tableView...
in this tableView i get the correct layout for my amount. But I haven´t give a special formatting to the tableView...
Why the BSP works differently at htmlb:inputField and htmlb:tableView
Thanks 4 help.

Hi Uday,
Its occurs because you're trying to access a objects with null reference. Or you forgot to create an instance or an error occurs during the instance creation. So You should put all your "Procedures and business logic" inside a Try/catch block. as follow.

The TRY block defines a guarded area whose class-based exceptions can be caught in the subsequent CATCH blocks. If no exception occurs in the TRY block and it reaches its end, the system continues the processing after ENDTRY. If a class-based exception occurs in the TRY block, the system searches for an exception handler in the same or an external TRY control structure.

How to handle null values in RTF templates

Hi - I have two groups in a report for different SQL and two formulas for each group, CF_ELE_CNT and CF_ELE_CNT1. In the template I use the below code to print or not print a section.
<?if:number(CF_ELE_CNT +CF_ELE_CNT1) >0?>
The problem is when there is no data in the second group its not creating the XML tag for CF_ELE_CNT1, though CF_ELE_CNT has 13, it still does not print that partucular section. If I remove CF_ELE_CNT1 from the condition it works fine. I was wondering how to handle this.
Any help would be appreciated!!
Thanks,
Rav

Hey Rav,
You can add a check to identify it the element/tag is present or not
<?if:(CF_ELE_CNT1)?> will give true, if the element is present otherwise falsesince you are adding the two elements, you have to add a or condition.
<?if:(CF_ELE_CNT and number(CF_ELE_CNT) >0 ) or ( CF_ELE_CNT1 and CF_ELE_CNT1 >0)?>
