Xpages File Download collect and display extra information - file-upload

Question

I'm using file upload and download control. I understand how to use the provided display columns, but how would I go about collecting other info about each uploaded file and then displaying it (i.e. Display Name and Notes that the user would enter)?
<xp:fileUpload id="fileUpload1"
value="#{document1.files}" style="width:80%"
useUploadname="false">
<xp:eventHandler event="onchange"
submit="true" refreshMode="complete"
disableValidators="true">
</xp:eventHandler>
</xp:fileUpload>
<xp:br></xp:br>
<xp:fileDownload rows="30" id="FD1"
displayLastModified="false" value="#{document1.files}"
style="width:98%" hideWhen="true" displayType="false"
displayCreated="true" rules="all"
lastModifiedTitle="Last Modified">
<xp:this.allowDelete><![CDATA[${javascript:database.queryAccessRoles(session.getEffectiveUserName()).contains('[Admin]')}]]></xp:this.allowDelete>
</xp:fileDownload>

Answer 1

If I understand your question correctly: you want to add additional information columns into the file download control that are derived from information stored or computed elsewhere, e.g. from a NotesItem (a field in the Notes document)?
In this case you need to construct your own output using a repeat control. You can render a table or a list - whatever you deem fit for display.
The “trick” is how to construct the URL for download - which is simply:
/yourdatabase.nsf/0/unid/AttachmentName?OpenAttachment
(typed off memory. You might need to double check syntax).
Word of caution: if you have lots of attachments, you might consider having separate documents for them and use a view - above URL works in views too. Saves you a versioning headache (in case multiple users can upload to the same document).
