GWT Exporter - How do i create an instance of object at runtime. Object type will be available as a string argument

Question

I am using the following code in GWT client Inside my jsni method I am using the following code, Assume that typeName is String argument

typeName = '$wnd.mysample.SampleButton'
var sample = new window[typeName]();
sample.addButton(name, parent);

SampleButton implements Exportable class, I used @ExportPackage("mysample") and @Export(all = true). In My entry module I called ExporterUtil.exportAll();

Note: if I replace
var sample = new $wnd.mysample.SampleButton() with new window[typeName]()
then it is working fine otherwise it is throwing undefined function called. Kindly let me know how to create an instance for the type in JSNI code

Answer 1

eval('var sample = $wnd.mysample.SampleButton();'); solves the issue.
