Birt Mapit not working in Birt-Viewer - birt

Question

I have created few maps using the mapit library of Birt. The maps are working fantastic in Birt Designer. However, when I put the same report in Birtviewer, the map does not load. My question is whether this is a compatibility issue of Mapit with java8 or birtviewer that it does not work in birt viewer?
My second question is how can I actually see whether the birt library file is being read correctly and whether it could be a problem with reading the library file?

Unlike "preview" mode, the frameset servlet loads the report through an ajax query. Problem is the Eclipse Webviewer does not make use of a framework such jquery to handle ajax: only the first html script tag is triggered.
Your sample works with the portlet viewer i developed because jquery handles all this ajax stuff automatically. To make it work with the frameset servlet of the Eclipse WebViewer, i tried a quick and dirty workaround, only tested with Chrome & Firefox:
1/ I added this fragment at the end of your first script tag:
setTimeout(function(){
console.log("Evaluate ajax html...");
var scripts = document.getElementsByName("scriptMap");
for (var i=0;i<scripts.length;i++) {
if (scripts[i].text!=null) eval(scripts[i].text)
}
}, 1000);
2/ I also added a name "scriptMap" allowing to select the 2 remaining script tags For example here is the last script:
<script name="scriptMap">
setTimeout(actuate.birt.maps.google.start, 1);
</script>
This way the sample runs finely with a WebViewer frameset.
Furthermore, if you need to deploy a flat file as relative path you can manage this by using a file URI such described below. It means in your sample you have to declare two distinct datasource, one for each file. I hope it will help.
