Subject Re: Problem with Trinidad's uploads

You can setup Tomahawk and Trinidad together. The problem here is you
are not taking into consideration how file upload works and which
library will be used to upload files. This applies to any jsf library
with a file upload solution.

There are two things any jsf library provides for file upload:

1. A jsf tag like t:inputFileUpload or tr:inputFile
2. A filter or FacesContext wrapper (special case for portlets) to
handle the incoming request.

Both trinidad and tomahawk has its own filter to handle this stuff.
>From page side it looks like this:

<form id="form1" enctype="multipart/form-data" ...>
  <!-- ... jsf generated html code -->
  <input type="file" ... />
  <!-- ... jsf generated html code -->

Note the part that says enctype="multipart/form-data". By default, JSF
does not handle this encode type, so you need to setup a filter that
handle this. Here is the important part: the filter that is setup ON
TOP will be the one who handle the request. If tomahawk is on top,
trinidad tr:inputFile will not work and viceversa, if trinidad is on
top, t:inputFileUpload will not work.

How to solve it? Put the entry for <filter-mapping> of your choice in
the right order on web.xml file. If your current setup does not work,
try to change the order. If that does not work, create a filter that
delegates first to the one you want and then to the other one.

Quite simple, isn't it?
