Hi Reddy,
You have button and you bind the "OnAction" to OnActionUpload() ...Am i right ??
What are you trying to do in OnActionUpload() method ? Please post the code.
Do you have any code in wdDoModifyView() method ? Is so please check you have if(fsirstTime) check or not ?

Hi Anil ,
Yes the button UploadFile is bound to onActionUploadFile(). method. There is no code in the wdDoModifyView() method.
public void wdDoInit()
{
IWDAttributeInfo attInfo =
wdContext.getNodeInfo().getAttribute(
IPrivateFileUploadView.IContextElement.FILE_RESOURCE);
attInfo.getModifiableSimpleType();
wdContext.currentContextElement().setDetailsVisibility(WDVisibility.NONE);
IWDMessageManager msgr=wdComponentAPI.getMessageManager();
msgr.reportSuccess("Entered into the init method()");
//@@end
}
....................................................................................
public void onActionUploadFile(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
{
//@@begin onActionUploadFile(ServerEvent)
// get attribute info for context attribute "FileUpload"
IWDMessageManager msgMgr1=wdComponentAPI.getMessageManager();
msgMgr1.reportSuccess("entered into the upload file method");
IWDAttributeInfo attInfo =
wdContext.getNodeInfo().getAttribute(
IPrivateFileUploadView.IContextElement.FILE_RESOURCE);
// get modifiable binary type from the attribute info
// requires type cast
IWDModifiableBinaryType binaryType =
(IWDModifiableBinaryType) attInfo.getModifiableSimpleType();
IPrivateFileUploadView.IContextElement element =
wdContext.currentContextElement();
// if a file in the FileUpload field exists
if (element.getFileResource() != null) {
try {
String mimeType = binaryType.getMimeType().toString();
byte[] file = element.getFileResource();
// get the size of the uploaded file
element.setFileSize(this.getFileSize(file));
// get the extension of the uploaded file
element.setFileExtension(binaryType.getMimeType().getFileExtension());
// NOTE: context attribute 'fileName' must not be set, because the
// FileUpload-UI-element property 'fileName' is bound to it. Consequently the
// fileName is automatically written to the context after file upload.
// set the details visibility attribute
element.setDetailsVisibility(WDVisibility.VISIBLE);
// report success message
wdComponentAPI.getMessageManager().reportMessage(
IMessageFileUpDownloadComp.SF_UPLOAD,
new Object[] { binaryType.getFileName()},
false);
} catch (Exception e) {
throw new WDRuntimeException(e);
}
}
// if no file in the FileUpload field exists
else {
// set the details visibility attribute, hide details
element.setDetailsVisibility(WDVisibility.NONE);
// report error message
IWDMessageManager msgMgr = wdComponentAPI.getMessageManager();
msgMgr.reportContextAttributeMessage(
element,
attInfo,
IMessageFileUpDownloadComp.NO_FILE,
new Object[] { "" },
true);
}
// clear the FileUpload context value attribute
element.setFileResource(null);
//@@end
}
Thanks and Regards
