FileUpload UI Question

[Former Member]

Hi All,

I have a question concerning the FileUpload UI, hope someone can answer me.

- Why before uploading a file, the following code have to execute first in wdDoInit()?

"wdContext.currentContextElement().node().getNodeInfo().

getAttribute("PdfSource");"

- Suppose the FileUpload will save the content to a binary context node, say "pdfObject" in view controller, can I map the "pdfObject" to component controller context in design time? Because I come across some sample that it will map the context node from view controller to component controller explicitly in code, so that the mapping occur at runtime, like "wdThis.wdGetTravelRequestCompController().wdGetContext().currentContextElement().setPdfObject(wdContext.currentContextElement().getPdfObject());", any reasons behind?

Thanks all,

Kelvin

hi,

The dataproperty must be bound to this value attribute of data type binary, so that the file can be uploaded as a byte array. At runtime, the binary data type can be enriched with data to allow the passing of related information when uploading a file.

Refer the data binding of the fileupload ui in this link.It will clear ur doubt

Thanks arun.

I read this but i don't know the meaning of "enriched with data to allow the passing of related information when uploading a file". Is there any example concerning this? does it mean some mime type like PDF or JPG information cannot be upload of getModifiableSimpleType not call in advance?

hi kl,

During runtime content in the file is uploaded as a byte array. The binary data type contains all the data about the file.

u refer this sample document and tutorials https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/webas/webdynpro/tu... on designing user interfaces with web dynpro - 23.htm

let me know if it helps,

hope this helps u,
