[GSOC 2010] GMaps Component
Hi everyone, I intend to create components that encapsulate some features of Maps Javascript API v3 The goal is allow the user have facilities to use maps like this [0]. I intend implement the features: - Geocoding - Markers - MapType - Add/Remove Controls - Size - Route Project: I' m thinking in create one base component and more two components, one to map routes and another to find adresses and insert markers. The base component will have features to: Geocoding, Add/Remove Controls, Size and others. What do you think about?

RE: t:grid, inPlace and rowIndex
Thanks Ville, that's very helpful. I think I'll just stick with my known object ref as the key and do a match on the list through iteration - saves some messing about. Ideally what I wanted from the grid is an index / ref that survives sorting (though has predictable behavior for additions / deletions) so it can be used for a get(index) on the source list - something like an originalIndex as opposed to a currentDisplayContextIndex - I'm would guess augmenting the model with that would be trivial but I'm aware these are general purpose components and can't really be expected to fit every specific requirement. In my case the object refs are a compound key, and when passed through an activation context require coercion, and then a check using key.equals(otherKey) per list entry until matched, which is just a few extra cpu cycles I could ideally get rid of. As you say the cost shouldn't be too much. The map backed grid seems too much square peg round hole for me. Thanks for the suggestions all the same.

Help me! How can i access a service in tapestry5 .
There is a project i have being doing recently. And now I have a big problem, hope you help me,thanks. I have to draw bar chart in a html page, the situation is that the bar chart is drawed by javascript, and the javascript code is produced by an action listener. I want that when i click the bar, i want to go to another tapestry page with parameters. The question is that how can i access the tapestry service with tag A(such as http://localhost:8080/app?service=someservice aaa in tapestry 4),just like when i click an ActionLink component, it can trigger an Action method. -- View this message in context: http://old.nabble.com/Help-me%21-How-can-i-access-a-service-in-tapestry5-.-tp29197261p29197261.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
