Resources for org.apache.myfaces.component.html.ext.* classes
Hi,
I'm trying to develop a new feature for t:dataTable (Tomahawk HtmlDataTable), in order to add a "detail" for a row.
My goal is explained in the message below, which is a discussion posted in the users list between me and Martin Marinschek.
During the development of this new feature, I'm facing the following problem.
The HtmlDataTable class (or the HtmlTableRenderer) does not belong to the "org.apache.myfaces.custom" package, so MyFacesResourceHandler can't be used for loading images or other resources.
But loading images used by the HtmlDataTable is what I want to obtain.
How do you think I should solve this problem?
Should I implement another ResourceHandler?
Or the current MyFacesResourceHandler should be modified?
Thanks a lot for your help.
---------------------------------------------------------------------
Sounds interesting.
I've had this problem before, and did solve it in a non-perfect way.
Essentially, I had to get rid of all columns - rendered out one
column, and made sure the columns of different rows would align by
using CSS and did the rest by hand.
I like the idea, though! Maybe you should add a feature request or go
even further and send us a patch?
regards,
Martin

Ok, now I'll continue my work with a temporary implementation of the
MyFacesResourceHandler, waiting for the official patch.
Do you think that I should insert an improvement request in JIRA?

I think we should modify the current resource-handler to allow for
serving resources out of the datatable directory as well.
