Adding a File object programatically in Plone using PloneFormGen

I'm writing a PloneFormGen custom action adapter in order to add a File object to a folder from the File Field in the form. Here is the script:

target = context.filefolder   
form = request.form    
uid = str(DateTime().millis())

target.invokeFactory("File", id=uid, file=form['arquivo-do-cv_file'])

obj开发者_JS百科 = target[uid]

"filefolder" is the name of a folder inside the parent folder for the PFG FormFolder. This script is configured to run with a Manager proxy role.

Problem is that the File objects created this way won't show the "Click here to download the file" link when I view them. The files can be downloaded though, if I suppress the "/view" part from the end of the URL. What am I missing when calling invokeFactory to create the File object?

UPDATE: What I meant is that I don't get the "filename - filetype, size in KBs (size in bytes)" link for the document, below the byline. When I create a File object using the normal Plone UI, it does show up.

I suspect nothing; I think that is the default behavior in Plone 4.

I just added a File and I don't see any "Click here to download the file".

And a quick search does not reveal the string "click here to download":

aclark@Alex-Clarks-MacBook-Pro:~/Developer/test-4.1/ > grep -ir "Click here to download" parts/omelette
parts/omelette/plone/app/jquerytools/browser/jquery.tools.plugins.js:                   (root.tagName == 'A' ? "<p>Click here to download latest version</p>" : 
parts/omelette/plone/app/jquerytools/browser/jquery.tools.plugins.min.js:" or greater is required</h2><h3>"+(g[0]>0?"Your version is "+g:"You have no flash plugin installed")+"</h3>"+(a.tagName=="A"?"<p>Click here to download latest version</p>":"<p>Download latest version from <a href='"+k+"'>here</a></p>");if(a.tagName=="A")a.onclick=function(){location.href=k}}if(b.onFail){var d=b.onFail.call(this);if(typeof d=="string")a.innerHTML=d}}if(i)window[b.id]=document.getElementById(b.id);f(this,{getRoot:function(){return a},getOptions:function(){return b},getConf:function(){return c},

I don't have a Plone instance to test it, but try to call processForm() after invokeFactory. It will:

• unmark creation flag;
• rename object according to title;
• reindex the object;
• invoke the after_creation script and fire the ObjectInitialized event.

These actions are detailed on Object Construction Lifecycle. Maybe some of these actions are needed to create the KB information you're after (I'm hoping it's the index).
