DATA:

cadena TYPE string,

FILENAME TYPE REF TO if_wd_context_node,

NODE_TABLE TYPE REF TO if_wd_context_node,

test TYPE string,

it_test TYPE if_componentcontroller=>Elements_Node_TABLE.

FILENAME = wd_context->get_child_node( name = `NODE_DOWNLOAD` ).

FILENAME->get_attribute(

exporting

name = `DOWNLOAD`

importing

value = cadena ).

NODE_TABLE = wd_context->get_child_node( name = `NODE_TABLE` ).

NODE_TABLE->get_static_attributes_table( IMPORTING table = it_test ).

CONCATENATE 'C:\' cadena INTO file.

call function 'GUI_DOWNLOAD'

exporting

filename = file

data_tab = it_test.

endmethod.

Hi Andres!

That's not correct. Avoid to use any function module starting with the name 'GUI ...' because almost all of them expect there is a fat client SAPGUI session active, what in a browser environment definitely is not the case.

InsteaD Especially have a close look to UIElement's fileDownload property allowSave!!!!!!!! In my case this works fine if porperty is set correctly.

Hope this helps!

Hello Andres,

You can try your scenario with three UI Elements - FileUpload, Button, FileDownload - and two context nodes - ctx_upload, ctx_download.

Using the FileUpload UI Element, you get the data in your context node ctx_upload (in x-string format). Now in the action handler of your button, write in the code which copies the Xstring from ctx_upload to ctx_download (bound to FileDownload UI Element). Next, when you click on the FileDownload UI Element, you will get your file.

You can of course use the same context node for both, but it just becomes more logical doing it this way and also opens up thoughts for real scenarios where Upload and Download happen on different views/components altogether.

Hope this helps.

I tried to do it by this way but yhe element FileDownload doesnt open a windows to navigate into folders, the FileUpload does it.

Any way, Im trying with a imputfield so simple, but I dont really know whats happening, because when arrive to the function the name 'C:\test.txt' and the table it_test area correct when I debug, but when enter the function in the browser show me an error

Hi,

check out the element file_download

You can find examples of this interface element in the system in the Web Dynpro application

WDR_TEST_UI_ELEMENTS, and in the component WDR_TEST_EVENTS in the View

FileDownload.

grtz,
