Hi guys,
I'm making some progress. wicketGlobalPostCallHandler doesn't seem to be
working for me, but I can do something like this after the iframe:
StringBuilder buffer = new StringBuilder( "<script>" );
buffer.append( "IFrameArea.populateContent( false, true, 'hello
world' );" );
buffer.append( "</script>" );
Label scriptLabel = new Label( "scriptLabel", buffer.toString() );
scriptLabel.setRenderBodyOnly( true );
scriptLabel.setEscapeModelStrings( false );
add( scriptLabel );
This will add a nice bit of Javascript into the whole lot that will call the
populateContent function (hurray).
Now the thing is, the text (hello world) flashes on the screen - then
disappears.
If I hit the 'refresh' button on the browser then the innerHTML 'hello
world' sticks. If I can solve this tricky problem then I think I'm good to
go.
Is it REALLY this simple? Why does Wicket have to be so cool?
Cheers, Graeme.
