I’m working with JSF2 and I want to display a map with the object

  • 0

I’m working with JSF2 and I want to display a map with the object gmap. As I saw, gmap object doesn’t exist anymore with richfaces 4.x, so I tried to import the gmap4jsf.jar to render my map…

To have an exemple I took a part of my code from the Richfaces demo here : Richfaces live demo

The map is displayed well, but if I want to control it (change the type, zoom,…) with the jsf elements from the rich:panel, I get an error in Firebug : “map is undefined”…
Can somebody help me to find out the problem please because I didn’t find the answer in other thread…
Here is my code:

    Ok I found it out…

    I had to define the name of the Javascript variable generated by JSF.
    So, I just added the attribut “jsVariable” to my gmap element.

    <m:map jsVariable="map" var="map" mapVar="map" gmapKey="#{gmapBean.gmapkey}" id="map" />

    Bye
