Hello folks,
i have created a custom widget with my own JavaScript code based on the
GMap demo. I have stripped everything GMap-specific and now when i run
my app, i can see in the source code that my JS has been loaded. Using
the LCA, I create the corresponding widget via the JSWriter.
My JS Code basically contains a qx class with just one property.
My constructor just contains an alert statement.
I also copied the _doActivate() and _doResize() methods from the GMaps
example and removed the GMap-specific stuff.
Any Ideas?
Any help would be greatly appreciated :)

Hi,
could you please add your LCA and the javascript implementation, so that
we can see what's going on. It's a little bit difficult without
sufficient information to analyse your problem.
Ciao

alert("constructor");
this.base( arguments );

alert("doActivate!");
var shell = null;
var parent = this.getParent();
while( shell == null && parent != null ) {

}
parent = parent.getParent();
}
if( shell != null ) {

}
},
load : function() {
alert("seller_id");
seller_id = "test";
},
_doResize : function() {
alert("_doResize called");
}
}
} );
My LCA looks like this:
package org.eclipse.rap.internal.ebay.ebaykit;
import java.io.IOException;
import org.eclipse.rwt.lifecycle.*;
import org.eclipse.swt.widgets.Control;
import org.eclipse.swt.widgets.Widget;
import org.eclipse.rap.demo.ebay.EBay;
public class EBayLCA extends AbstractWidgetLCA {
private static final String JS_PROP_SELLER_ID = "seller_id";
private static final String PROP_SELLER_ID = "seller_id";
public void preserveValues( final Widget widget ) {
ControlLCAUtil.preserveValues( ( Control )widget );
IWidgetAdapter adapter = WidgetUtil.getAdapter( widget );
adapter.preserve( PROP_SELLER_ID, ( ( EBay )widget ).getSeller_id() );
}
public void readData( final Widget widget ) {
}
public void renderInitialization( final Widget widget ) throws
IOException {
JSWriter writer = JSWriter.getWriterFor( widget );
String id = WidgetUtil.getId( widget );
writer.newWidget( "org.eclipse.rap.demo.ebay.EBay", new Object[] {
id } );
writer.set( "appearance", "composite" );
writer.set( "overflow", "hidden" );
ControlLCAUtil.writeStyleFlags( (EBay)widget );
}
public void renderChanges( final Widget widget ) throws IOException {
EBay ebay = ( EBay )widget;
ControlLCAUtil.writeChanges( ebay );
JSWriter writer = JSWriter.getWriterFor( widget );
writer.set( PROP_SELLER_ID, JS_PROP_SELLER_ID, ebay.getSeller_id() );
}
public void renderDispose( final Widget widget ) throws IOException {
JSWriter writer = JSWriter.getWriterFor( widget );
writer.dispose();
}
public void createResetHandlerCalls( String typePoolId ) throws
IOException
{
// TODO Auto-generated method stub
}
public String getTypePoolId( Widget widget )
{
// TODO Auto-generated method stub
return null;
}
}
I now would imagine that when my ebay object is created, it should call
the constructor. When I inspect the DOM in my browser, I can see my
org.eclipse.rap.demo.ebay.EBay object.

Hi Markus,
your code looks good so far. If you work with Firebug you can try to
create a new instance of your widget in the Firebug console and check
that the alert is raised.
You said that the widget exists in the DOM tree. Thus, the constructor
must have been called. What exactly is the problem? Is the widget
invisible or is it displayed correctly but the alert is not brought up?

Hi,
thanks for verifying my code.
My widget on the client side contains nothing but an empty constructor
with the alert statement and one property. I didn't code further because
I wanted to check the functionality of my code so far :)
The shell of the widget is displayed correctly, but of course it's empty
because I haven't put something in it.
Greetings,
Markus
P.S.: How do I create a new instance of my widget with Firebug?

Now i got my alert message, so i can be sure the class definition is
correctly loaded.
So it seems, that in my LCA the JSWriter does not create the widget on
the client-side, am I right? But I can't find a mistake there.
The object i found in the DOM would be just the class definition i guess.
So what am I missing here?

I got it working.
The problem was that the LCA wasn't created at all during startup.
Seemed to be some issue in my package naming conventions.
In order to avoid such mistakes in future projects, i would like to
implement the getAdapter(Class adapter) method in my widgets.
In this case, would this be my EBay() class in the package which also
holds the resources? How do I then call the getAdapter method? By hand
or is there some magic involved which calls this method?
Thanks for your help!

Hi Markus,
nice to hear that you solved your problem. Yes, the LCAs are found by
package and class name convention. If your LCA is not found, the
superclass LCA is looked up. That's what probably happened to you.
But I don't understand how implenting the Adaptable interface should
work around this kind of problem? The Adapter mechanism is only used to
access non-API properties of some widgets.
Best regards,
Ralf
