Hi,

If set up a fileupload on the onClick trigger of a button in one of the forms in my application. When I click in the 'Examine' button a popup window appears to inform me that

Invalid ID: z_ma_l3!iframe. Cause: reserved words not allowed: [arg, page, session, event, spaceOwner, desktop, self]
11-dic-2008 9:34:53 org.zkoss.zk.ui.impl.UiEngineImpl handleError:1107

The whole trace reads

Invalid ID: z_ma_l3!iframe. Cause: reserved words not allowed: [arg, page, session, event, spaceOwner, desktop, self]
11-dic-2008 9:34:53 org.zkoss.zk.ui.impl.UiEngineImpl handleError:1107

At first I thought it could be due to some error in my form or script, but I tried to copy the following from the online demo (which of course works perfectly) and insert it into my form:

<button label="Upload">
		<attribute name="onClick">{
			Object media = Fileupload.get();
			if (media instanceof org.zkoss.util.media.Media[]) {
				org.zkoss.util.media.Media[] medias = (org.zkoss.util.media.Media [])media;
				for (int i = 0; i < medias.length; i++) {
					Image image = new Image();
					image.setContent(medias<i >);
					image.setParent(pics);
				}
			} else if (media != null)
				Messagebox.show("Not an image: "+media, "Error", Messagebox.OK, Messagebox.ERROR);
		}</attribute>
	</button>

The result was the same. If I switch back to zk3.5.1 everything works fine.

I guess the reason for this must lie on the differences between my environment and that of the server running the demo. I'm using the maven jetty plugin 6.1.11 and have the following zk.xml configuration:

<zk>
    <listener>
        <description>ThreadLocal Synchronization Listener</description>
        <listener-class>org.zkoss.zkplus.util.ThreadLocalListener</listener-class>
    </listener>
    <preference>
        <name>ThreadLocal</name>
        <value>org.springframework.security.context.ThreadLocalSecurityContextHolderStrategy=contextHolder</value>
    </preference>
</zk>

With kind regards
