I have to start by stating that leaflet.js is plain awesomeness! Started yesterday and have decent results already.
Is it possible to populate map markers with a CMS? So the client can login to their websites backend (probably a new one in addition to their existing one) and add, change and remove markers (including position, icon, layer and popup content)...
If yes, where would I start educating myself about that?
Thank you very much!

I just need some links, where to begin. I am not really familiar with OSM, but I want to create little website with a world map, where visitors of my site can simply add places with a descriptopn. I don't know where to start. Are there any pre-coded templates for a CMS like Wordpress or just non-CMS templates?
Have a look at OpenLayers. There is a QuickStart Tutorial on how to add a map. If you want to add a Marker by a click on the map have a look at ClickHandlers (example can be seen here). What you would have to change is showing a field onClick, where the user can enter the description. What could be also from interest for you is the OpenLayers.Popup.
If the result should be stored, you have to save the description and marker position into a database, so you probably will need some server side implementation for your idea.
I have a Joomla site I am developing that centers around designer handbags of a particular label
(not my site, it's a client's). It is not an ecommerce site, more of a social site.
What I am looking to do is present the user with a list of handbag styles and patterns so that
they can mark which items they have and which items they need.
Then two sections of content would be generated - one listing what they have and one listing what
they need.
I would also need to be able to include a direct menu link to that page.
Any ideas would be appreciated!
Probably the best way to do that would be to extend either community builder or JomSocial. Both have the ability to have custom user profiles which would go a long way to creating what you are looking for. You may even be able to do everything you want within the basic structure of one of those extensions.
My problem is very similar to the one posted here:
http://www.utteraccess.com/forum/Plotting-Addresses-Maps-t1968130.html
except that thread never found any solutions. Basically, I'm working on an Access form that has a datasheet as a subform. Upon clicking a button on the main form I'm trying to make it so that a browser window opens up and, using the address columns from the spreadsheet data in the subform, plot all the address markers listed. I've looked up a lot of ways to attempt this but I've yet to find a way that seems to work.
I'm not even sure if it's possible to plot multiple markers on Google Maps, but according to research (and after trying it myself) it seems like it isn't, although I don't want to rule it out entirely because I'm still not 100% sure. However I know both Google Earth and batchgeo.com do allow this. I still want to try and do this on Google Maps, but if that doesn't work I want to try to do it using batchgeo.com and if that still doesn't work, then Google Earth (I don't want to make the user download external software if possible).
If it helps, from what I've read API's seem like a useful tool, though I'm not sure how to apply it to an Access form, it seems more like a way to embed to already existing websites.
I'd really appreciate if someone could help me figure out how to approach this problem!
Maybe this would help?

It is Excel but should be translatable.
Here is another example, this time using Access:

You're right. There's no way, that I'm aware of, to embed a Google Maps object in a form (like an ActiveX control). Microsoft MapPoint is a software product that lets you do Map integration by way of an ActiveX control (no need to use HTML and/or javascript).
What I usually do on a project like you're working on is I get my HTML page working the way I want it to, outside and independent of MS Access. You should be able to program and test the HTML file locally without having to use an actual web server. Just use something like NotePad++ or Sublime Text Editor 2 to write your HTML and Javascript and then open the file in your browser to see if it works. I'm quite sure you'll need to use Javascript in your HTML page to make this work. That's what the Google Maps API is all about.
After you have your webpage working, then you will have to go into Access and write code to create that web page on the fly with the address data for the current data set. You can just write it out to the Windows Temp folder and then open your browser control that that web page.
Julian Knight's answer links to more specifics on how to create the HTML page on the fly. It looks like gobble-de-gook, mostly because it is. Outputting HTML/Javascript/CSS from VBA is far less than optimal. This is why you troubleshoot it outside of Access, as much as you can.
On the google website there an example of a simple GWT appliatoin, following is a link:
http://code.google.com/webtoolkit/doc/1.6/tutorial/create.html
The above application has a host page:StockWatcher.html
and StockWatcher.java is the entry point.
If I wanted to add more html pages to this application, we keep one single host page and the entry point will add different panels depending on which link the user clicked on? In this case, how to know which link the user clicked on? If I create a navigation panel and each link has a request parameter, then after the user clicks on the link, How to get the request parameter?
Are there any tutorials available online on how to create a fully functional application? The one example google provides is too simple.
Thanks so much in advance
You have two options to have multiple page web application using gwt.
1) Use gwt history feature and listen for the history change. In this approach at the initial page load itself browser downloads all the javascripts(Including the widgets which are not useful in current link). Still this can be avoided by using gwt code splitting.
2) Create multiple modules. In this case you have to create multiple html pages and GWT entry points. For each major functionality create a gwt module and link that with [modulename].html file. In this approach browser downloads only particular feature's javascript. Not all the javascripts.
Based on your application requirement you can pick one of the option. IMHO I would suggesst second option.
I've generated the backend of my application, and am now just 'jazzing' the forms up (adding correct labels, validation rules etc).
One thing I'd like to do is add a map (Google) which updates the marker as an address is entered into the form, then allows the user to drag it to correct the lat/lng should it be a little off.
My question is, how can I customise the output of the form - I've read the docs (1.0,1.1,1.2 also) and it all seems very confusing. Customising forms not generated with the admin generator I know how to do using renderRow(); etc; but finding a way to add a little bit of HTML to the forms is making my eyes hurt! There's so much out of date stuff on the web regarding Symfony it's hard to know what to trust!
If anyone can point me in the right direction that'd be great.
Best Regards,
Rich
Maybe you can start by looking at this plugin : http://www.symfony-project.org/plugins/sfEasyGMapPlugin .
For your question, customizing the forms can be done by creating your own widgets and using them as default widgets.
