Question

I am sending a visualization.datasource.datatable.DataTable from the server side in my GWT app. I am setting a custom property.

 datatable.setCustomProperty("key","value");

i can see the property being set and the json returned has a

"table": {
    "rows":[....]
    "cols":[...]
    "p":{ "key":"value"}
}

but how do i retrieve it using an instance of visualization.client.datatable?
there is a

getProperty(row,col,name)

method, but now sure of its usage.

I do not think that a method to retrieve custom properties on data table is exposed.

You can check that in the javadoc of version 1.1

Though you can query your dataTable using JSNI. The javascript method to query custom property set on DataTable is available in its javascript documentation. The GWT library is just a wrapper on the javascript library. So you can do something like given below:

private native void getProp(DataTable dataTable, String name) /*-{
    alert(dataTable.getTableProperty(name));
}-*/;
