gmap2 and map creation
I have another question related to wicket-contrib-gmap2:
I'm trying to create a new GMap2 component in response to an AJAX request.
My code looks much like the code in the constructor of class
wicket.contrib.examples.gmap.controls.HomePage(), in the gmap2 examples,
which says:
final GMap2 topMap = new GMap2("topPanel", LOCALHOST);
topMap.setZoom(10);
When I try to make calls such as setZoom() on the newly created GMap2, an
exception is thrown:
Caused by: org.apache.wicket.WicketRuntimeException: This component is not
(yet) coupled to a page. It has to be able to find the page it is supposed
to operate in before you can call this method (Component#getMarkupId)
at org.apache.wicket.Component.getMarkupId(Component.java:1201)
at wicket.contrib.gmap.GMap2.getJSinvoke(GMap2.java:399)
at wicket.contrib.gmap.GMap2.getJSsetZoom(GMap2.java:424)
at wicket.contrib.gmap.GMap2.setZoom(GMap2.java:353)
For various reasons, it's not easy for me to add this component into the
page hierarchy at the time of creation - it's basically being created by a
factory class that doesn't necessarily know about the rest of the world.
The example code works because the creation is not in an Ajax request, so
this code path isn't hit.
It looks like most of the operations on GMap2 require a markup id in this
way. I tried setting the markup id manually on the GMap2 instance, but that
didn't help; it's the markup id of the contained WebMarkupContainer (the
"map" member) that's looked for:
public String getJSinvoke(String invocation)
{
return "Wicket.maps['" + map.getMarkupId() + "']." + invocation +
";";
}
Any suggestions for how I can get around this? It does seem like a
reasonable thing to do, I think? I haven't seen this kind of problem with
any other Wicket components that are created in the same way...
(This is with Wicket 1.3 beta 4, and the head of gmap2)
Many thanks,
Jan

No problem, of course! :-)
I just committed a patch. Could you check if it suits your needs?
The patch adds checks for "isAttached()" in some operations, but not all.
So I was still getting some similar errors, for example in GMap2.addControl
().
I've worked around this so far by applying a patch in GMap2, adding the
middle line:
map = new WebMarkupContainer("map");
map.setMarkupId("gmapInternalMarkupId"); // Work around problem of
non-attached component
map.setOutputMarkupId(true);
While this is a bit of a hack, could the problem be better fixed in a
similar way? That would avoid having to remember to do the check for every
operation in GMap2.
Also could you check if the codechange in the ManyPanel is asking for

Looks like it yes, but as discussed above, it only calls setZoom() and not
all the other operations that may be called on the component before it's
added into the page hierarchy.

Jan

I'm pretty sure I'm using the latest version:

Actually, that stack trace might have been misleading as I had been playing
around with the code in GMap2... Here's a stack trace with the original
version:

Looking at the line numbers I'd ask, are you sure you are running the
latest wicket-contrib-gmap2?
like

Also the description sounds like something we might have covered in the

Have fun,
