*** EPrints community wiki - http://wiki.eprints.org/
Hi list,

I am interested in altering ItemRef to add a button that would allow
users to more fully search for a value by creating a popup window that
would allow them to find the itemref value and have it then push the
value into the field. I've had a stab at modifying
EPrints::MetaField::ItemRef but can't seem to work out how you would
feed it another param via the workflow system. I feel that this is
distinct from the input_lookup_url because I aim to popup a new window
to provide the ability to search for the correct Itemref ID instead of
having to remember just what number should be used (rather unfriendly). 

I've had a dig around the code base and nothing immediately obvious
became apparent. Anyone got any suggestions for how I'd implement this
feature?

Cheers,

Sam

I think the "EPrints" way to do this is to build an InputForm ↵
component
plugin. If you take a look at
Plugin::InputForm::Component::Field::Subbject (phew) you can see how a
"widget" was built to enable searching of subjects (stuff to do with
_internal_ actions).

I've also done input widgets before that combine an InputForm component
with some AJAX (so you don't need to mess around with _internal_ action
passing).

All the best,
Tim.

I am very much interested in this widget. In fact, I want the subject
chooser to be an AJAX file. Any hints how can it be done?

Hi folks,

as we have very long abstracts on summary page in our repos, it would be 
nice if it scrolls sometimes.

I tried to apply

http://www.eprints.org/tech.php/thread-6707.html

But in eprint_render.pl with

	if( $eprint->is_set( "abstract" ) )
		{
			my $div = $session->make_element( "div", ↵
					class=>"ep_block" );
			...
			
			my $iframe = $session->make_element( "iframe", 					style=> 
"width:90%", src=> "data=text/html, ↵
					<html><body>". 								 
$eprint->render_value("abstract"). ↵
						"</body></html>" );
			$div->appendChild( $iframe );								
		}

it does not work. An error message tells

eprint_status not set
------------------------------------------------------------------
EPrints System Error inducing stack dump
  at /opt/eprints3/perl_lib/EPrints.pm line 91
         EPrints::abort('eprint_status not set') called at 
/opt/eprints3/perl_lib/EPrints/DataObj/EPrint.pm line 544
 
EPrints::DataObj::EPrint::get_dataset('EPrints::DataObj::EPrint=HASH(0x2e5b07c)') 
called at /opt/eprints3/bin/generate_abstracts line 177

Perhaps an error in appliance of DOM with make_element? Could anybody 
indicate the problem?


Best regards,
Andrea

Why not try using a div with an overflow;

if ( $eprint->is_set( "abstract" ) )
{
	my $div = $session->make_element( "div", ↵
class=>"ep_block" );
	...
	
	my $abstract_div = $sesssion->make_element( "div", ↵
style=>"width:  
90%, height: 200px, overflow-y: auto;" );
	$abstract_div->appendChild( $eprint->render_value( "abstract" ↵
) );
}

This way if the abstract text is long enough and makes the text cause  
the div to go taller than 200px a scrollbar will appear. If you find  
that overflow-y does not work on all browsers give overflow a try.

Hi Marcus,

that looks fine. Thank you for the hint.

Could you tell me please in what way overflow-y is perhaps better than 
iframe?

Andrea

Hi Andrea,

I would argue that an iframe is used to render another URL and not  
content that comes down as part of that page request.. Also it's a  
case that some browsers may have a hiccup with iframes, although  
without googling around the place I am not sure of the truthfulness of  
this statement :)
