Aynchronous content loading

[jarekevi]

I'm using version LGPL and I bought v3.1 Pro
i GPL version I load I have loading of the content asynchronously when user click on the expand icon in the grid and it was working well
I must switch to pro version because of excel export from the grid
but it beak the asynchronous content loading

Code that does not work in pro version

@Override
protected Canvas getExpansionComponent(final ListGridRecord record) {
super.getExpansionComponent(record);
StringExpansionComponent layout = new StringExpansionComponent();
layout.setText(((MessageModel) record.getAttributeAsObject(MessageModel._dump)).getFirst200());
record.setAttribute(MessageModel._expansionComponentID, layout.getID());
layout.record=record;
return layout;
}
