Native method compilation problem

[Christophe]

Hi,

I have a compilation problem with a 'javascript' native methid, but I
can not find the problem. Can someone help ?

public native void defineJS() /*-{
var that = this;
$wnd.modifyTabTitle = function(title) {

$entry(th...@fr.gouv.finances.dgfip.xemelios.web2.gwt.client.widgets.navigate.PnlShowDocument::__modifyTabTitle(Ljava/
lang/String;)(title));
};
}-*/;


Thanks a lot in davance,
Christophe

If it doesn't compile, there must be an error message. They're generally useful for debugging.

Don't know what the issue is, but there are two issues here, a syntax one, and a bug:

1. there should be a "." between "that" and "@fr.gouv.finances.…": that.@fr.gouv.finances.…
2. the $entry() is not correctly used: $entry() wraps a function so that calling the returned function executes the scheduledEntry and scheduledFinally commands, and route exceptions through the GWT.UncaughtExceptionHandler; but here you're wrapping the return value of your method, after calling it, and you don't use the return value of $entry(); so it's useless.
   Best is to wrap your anonymous function with $entry: $wnd.modifyTabTitle = $entry(function(title) { ... });
