Auto-completion hints and manual page link do not work

[Masterxilo]

This is Mathematica 10.

You can hover over built-in Symbols to display auto-completion information, but this does not work correctly with ApplicationMaker's functions.

Also I cannot press F1 to get to the help page of the command under the cursor.

Pressing F1 to get to the help page works if I rebuild the index as follows:

amdocdir = 
  FileNameJoin[{$UserBaseDirectory, "Applications", 
    "ApplicationMaker", "Documentation", "English"}];

indir = FileNameJoin[{amdocdir, "Index"}]
Quiet@DeleteDirectory[indir, DeleteContents -> True];
Quiet@CreateDirectory@indir;

ind = DocumentationSearch`NewDocumentationNotebookIndexer[
   indir <> 
    "\\"(*final \\ seems to be needed by \
NewDocumentationNotebookIndexer*)];
Do[
 Print@f;
 DocumentationSearch`AddDocumentationNotebook[ind, f];

 , {f, FileNames[WordCharacter ~~ ___ ~~ ".nb",

   FileNameJoin[{amdocdir}~Join~#] & /@ {
     {"Guides"},
     {"Tutorials"},
     {"ReferencePages", "Symbols"}
     }
   ]}

 ]

DocumentationSearch`CloseDocumentationNotebookIndexer[ind];

But the blue (i) icon still does not work and the auto-completion info is still messed up.
