Hi,
I made a simple Chart component using Google charts api.
(I also use tapestry5-jquery)
I have the following in this component: (stripped down)
@SetupRender
void setup() {
javascriptSupport.importJavaScriptLibrary("https://www.google.com/jsapi";);
}
@AfterRender
void afterRender() {
JSONObject spec = new JSONObject();
//add needed stuff to spec
javascriptSupport.addInitializerCall("drawChart", spec);
}
In the javascript initializer "drawChart" I have the following: (stripped
down)
function drawChart(spec) {
google.load('visualization', '1', {
packages : [ 'corechart' ],
callback : function() {
chart.draw(spec.data, spec.options);
}
});
}
In a page where I use this chart I have a form that on submit updates a zone
showing the chart. The first time it does not show the chart, but when I
submit for a second time it does work perfectly.
The first submit I get the following in my firebug console:
TypeError: callbacks[(i + 1)] is undefined
callbacks[i + 1].call(this);
(tapestry-jquery.js line 966)
I have no clue what is going on here, or how to fix this. Maybe my approach
is just completely wrong here?
