OK, so this is pretty obscure, but the good news is that there are easy
workarounds to the problem.

This code fails:

  public Object download() { return new Clob(...); }

but this code will work:

  public Clob download() { return new Clob(...); }

(ie specify Clob not Object as return type)

and so will:

  public Object download(String filename) { return new
Clob(...); }

(ie take at least 1 argument).



The issue is down to the way in which we set up the Wicket viewer's Ajax
handlers; downloadable objects with no-args have to be dealt with in a
certain way, and we look at the action signature to try to guess.

I've raised a ticket [6] to see if we can support all the cases, but I
don't see it as a high priority to fix.


Thx

PS: probably tangential to what you are working on, but the isisaddons has
a docx module [7] for mail merges.  And Jeroen experimented with xdocreport
[8], which looks simpler still; we will probably make a very minimal module
around that, too.

Re: Returning content as file...?

[Kevin Meyer]

I've added the project to github on [1]. Sorry - I've not put much effort
into consolidating the menu/service actions, most of them are visible even
when not appropriate.

I've implemented the "convert and send as file" as a service at [2].

For convenience, I've created a fixture script.
After loading the fixture, go to "Reports" and use "Find First" to get a
report[3], then choose "Print as Html" - which fails with the exception.
"Print As Latex" just returns a String.

FYI, ultimately I'd like to install an editor (probably epiceditor[5]) to
use a rich markup for the "Description" field of a project[4]. That's
where I was trying to insert the @Html annotation.

Next steps are to insert transformers (like XSLT) into the ReportPrinters
to run-time select which properties of the Project to include in the
Report, but first I want to get the current ideas actually working.

Regards,
Kevin

Will do. At work at the moment - will send later this evening when I look
at the code again (will probably just add the PoC to my github account -
though it's embarrasingly rough right now).

OK, thanks for that Martin.  Makes me wonder why it works in other
circumstances, though.

Kevin... could you mail (the relevant bits of) the action any
annotations, is it on a menu service, or a contribution service, or a
domain entity or view model or mixin?  Would like to try to reproduce the
issue first (even though I'm sure the fix will probably be to do what
Martin has suggested)

, i.e. we are in the constructor.
Later it seems there is a call #getPage() but since ActionPanel is not yet
added to its parent there is no path to the page.
Simple fix would be to #buildGui() in #onInitialize().

Returning content as file...?

[Kevin Meyer]

Hi,

I'm sure this has been described before, but could someone point me to
some instructions on how to have the output from a service sent back to
the user as a file? (markmail is good, but I'm struggling with what to
search for!)

For example, I want the results of "printToLatex(Report report)" to be
sent back the the user as a LaTeX file with a name derived from
report.getName().
My method signature right now is "String printToLatex(Report report)".

How does this differ from the service action "printToHtml(Report report)"
which should return only the resulting HTML to the browser? Is that
possible?

Thanks in advance,
Kevin

umm, ok... no clues there unfortunately.  Any Javascript errors in Chrome's
console?

Also, which version are you running against?  I'm guessing 1.10.0 ?

Hi Dan,

Re: Returning content as file...?

[Dan Haywood]

Probably need to see some more of the stack trace.

You could also run in debug and set a breakpoint as to when the first
exception is thrown, to provide a bit more context..
