Hi,
If i create a context attribute dynamically as follow:
IWDAttributeInfo FieldContext = wdContext.wdGetAPI().getRootNodeInfo().addAttribute("FldContext", "ddic:com.sap.dictionary.string");
can i, instead writing ddic:com.sap.dictionary.string, refer dynamically to a type in the the dictonary.
hope it's clear
Joseph

Hi Joseph,
As Valery said, you can use IDataType class to get the datatype of the attribute
IWDAttributeInfo attr1 = wdContext.getNodeInfo().getAttribute("vaVisibility");
IDataType dt1 = attr1.getDataType();
String strDataTypeClassName = dt1.getAssociatedClass().getName();
IWDAttributeInfo FieldContext = wdContext.wdGetAPI().getRootNodeInfo().addAttribute("FldContext", strDataTypeClassName);
Hope this is want you are looking for. If you require any further clarification let me know.

Ok,
I'm getting from bapi BAPI_HELPVALUES_GET a table with the meta data (name of coloumn, type, lenght of the column) of a search help.
Now in my webdynpro I would like to build InputField with the same meta data. I don't want to set all my field with the string type.

Joseph, my pardons, but what requirements force you to hand-code things carried out by WD Adaptive RFC generator automatically???
Believe me -- reconstructing IDataType by DD definition is a hard thing, and sooner or later force you to enter non-public WD APIs.
Could you describe your requirements from higher-level perspective?

Hi Valery,
I want to build Search Help (F4 in SAP) in my webdynpro.
So I send Business Object and searh help name to a bapi, and the bapi return me the sturcture of the search help. In fact it return me the name of the column, the lengh and the ID of the column.
Now that I got all this I need to build a table and also fields name that correspond to column that compose the search help, to let the user make search.
So I was thinking that i want my field reflect the "reality". That means that if I have a field like BUKRS (company Code), I want the lengh of this field to be 4 Char. And not to be only a String field with no specific lengh.
Thank you Valery,
Joseph
ok I think I resolved it.
List listDesc = wdContext.currentOutputValElement().modelObject().getDescription_For_Helpvalues();
For(j=0; j<listDesc.size();j++){
Bapif4E desc = (Bapif4E)listDesc.get(j);
IWDInputField field = (IWDInputField)view.createElement(IWDInputField.class, "Fld"+j);
field.setLength(Integer.parseInt(desc.getLeng()));
}

Hi Joseph,
I mean whether your requirement to display arbitrary ABAP structure / table or just to work over some <b>concrete</b> RFC function and its paramteres?
If the second is true then why not to use Adaptive RFC Model generated? You will get all value help, length restriction etc automatically...
VS
Adaptive RFC Model generated? can you tell more on this?
I'm using 2 Bapi
1)BAPI_HELPVALUES_GET_SEARCHHELP
2)BAPI_HELPVALUES_GET
After executing the second, what else can I do? I loop trought table DESCRIPTION_FOR_HELPVALUES, build my table and then loop on table HELPVALUES ans assign the value to their respective column.
Am i missing a step?
No, you are not missing a point.
But what you do is getting type metada for constructing WD Data Dictionary type. As far as I understand this task could not be disconnected from entering data itself (unless you are emulating ABAP development environment in WD
Please re-read my recent 2 posts in this topic: I were asking you what is top-level task for you application, what data should be edited? Hardly believe that reconstructing value help with BAPI calls could be such one
VS
Hi Valery,
I'm not using metag for constructing WD data dictionary.
I loop on the table that contain the description of my fields and then create fields/label, and also draw my table that conatins the values
In fact i made it like that and it works fine.
thank you Valery and Santhosh for your help

Yes, you may get IDataType from other attribute or from CMIModelClassInfo (like from model class info of Dynamic RFC Model Class).

Hi Joseph,
Could you explain the scenario in detail? In what case, you want to refer to the dictionary data type at runtime?
