Yep... that did the trick! Thanks much for all your help!

Here's what I did.... I made a copy of AttributeAppender, and changed
the method newValue( String, String ) to this:
protected String newValue(String currentValue, String appendValue)
{
final int appendValueLen = (appendValue == null) ? 0 :
appendValue.length();
final AppendingStringBuffer sb;
// initializes the AppendStringBuffer
if (currentValue == null)
{
sb = new AppendingStringBuffer(appendValueLen +
separator.length());
}
else
{
sb = new AppendingStringBuffer(currentValue.length() +
appendValueLen +
separator.length());
}
// only append the value when it is not empty.
if (!Strings.isEmpty(appendValue))
{
sb.append(appendValue);
if ( ( currentValue != null ) &&
!Strings.isEmpty(currentValue) ) {
sb.append(separator);
sb.append(currentValue);
}
}
else
{
if ( ( currentValue != null ) &&
!Strings.isEmpty(currentValue) ) {
sb.append(currentValue);
}
}
return sb.toString();
}

yes, if you are gonna use this in several places, creating a class
like AttributePrepender may be a better idea.

I remember Martijn advising to copy/paste AttributeAppender and transforming
it to AttributePrepender for such a use case...
Best,

Thanks for the suggestion...
It appears as though I need to insert the attribute before the existing
onclick attribute. How do I retrieve the existing onclick attribute? My
hope is to retrieve the existing onclick attribute so I can prepend my
onclick action and use AttributeModifier to replace the existing with the
newly prepended content.
Thanks much,

Hi,
I'm new to wicket, and am working on my first app. Great alternative to
other WebUI frameworks!
I've added a link to my panel using this code:
Link deleteReportLink = new Link( "deletereport" ) {
@Override
public void onClick() {
System.out.println("deleting report" );
service.deleteReport( selectedReport );
}
};
add( deleteReportLink );
// add a confirmation to the Delete Report operation
deleteReportLink.add(
new SimpleAttributeModifier( "onclick", "return confirm( 'Are
you
sure?');" )
);
Here's the markup:
<a href="#" wicket:id="deletereport">Delete Report</a>
<!-- <input type="button" wicket:id="deletereport" value="Delete
Report"
/> -->
<!-- <button type="button" wicket:id="deletereport">Delete
Report</button>
-->
In the markup, when I use an 'a' tag the javascript confirmation dialog
works fine along with the onClick() override. When I use it with either
of
the (commented out) button inputs, the dialog appears, but the
'onClick()'
override is never executed.
I'd much rather this work with a button and not a hyperlink.
Any ideas or help is greatly appreciated.
