> Project: MyFaces ADF-Faces
> Issue Type: Bug
> Reporter: Jeanne Waldman
> Assigned To: Jeanne Waldman
>
> Set your browser to an unknown agent to test this.
> This can also be reproduced by using Mozilla:
> To spoof the user agent in Mozilla firefox:
> 1: open the advanced config settings (type about:config in the address bar)
> 2: add a property with key "general.useragent.override" and value an empty
> string or anything you like
> 3: access any jspx demo page and you get this:

> Debugging into it I found the problem really occurs at:
> CoreRenderer's
> static public boolean isIE(RenderingContext arc)
> {
> return (arc.getAgent().getAgentName().equals(Agent.AGENT_IE));
> }
> because the AgentName for an unknown agent is null.
> Agent's API says that getAgentName returns null for unknown agents.
> * @return return the canonical name of the agent (browser application).
> * Returns <code>null</code> if not available.
> * <br>E.g. gecko, ie, opera, pocketie
> */
> public String getAgentName();
> And if I fix this, then there are other problems, like in TreeRenderer:
> boolean isMacOS =
> rc.getAgent().getPlatformName().equals(Agent.PLATFORM_MACOS);
> We need a solution where if the agent is unknown, all the properties are
> unknown so we don't get the null pointer exceptions.
