Hi there,
I’m using vaadin 6.8.6 and I have developed a custom component.
Unfortunately I got a javascript error but I don’t understand why.
This is the error (javascript are ‘prettified’):
avaScriptException: (TypeError): size.lastIndexOf is not a function
fileName: http://localhost:8080/overviewtable/VAADIN/widgetsets/com.mycompany.internal.widgets.overview.OverviewtableWidgetset/15991E62DE94678CD75737CB4F000063.cache.htmlRight now, VOverviewTable.updateFromUIDL is never called. But I understand that a client-side error could prevent the call of this method.
The error happens when the component is being rendered in the page and the error is in vaadin console. Server side I don’t have any error.
Thanks for any help.
Server side component:
public class OverviewTable extends AbstractComponent {
private static final long serialVersionUID = -3387341007298022602L;
private String data = "";
private String theme = "twitter";
@Override
public void paintContent(PaintTarget target) throws PaintException {
super.paintContent(target);
target.addAttribute("data", data);
target.addAttribute("height", getHeight());
target.addAttribute("width", getWidth());
target.addAttribute("theme", theme);
}

super.changeVariables(source, variables);
}
/**

public void setJSONData(String data){
this.data = data;
requestRepaint();
}
}client side component:
