no no no, this component is good but actually use less as it has no documentation,
by the way, you should put js files in your project files folder
- markerclusterer.js
- markerwithlabel_packed.js
- uniGmap.css
then run application again
another problem not solved, when use this component for another form (not main form) it didn't load until refressh broswer
version is use, 1.4.8 for unigui 1.5xxx
and i think there's some configuration or code missed from mention of developer
