Re: Need to enable parallel download .
I have few JavaScripts (abt 35kb) getting downloaded at the beginning even thought it is used later in the app.Can i load javascript lazily with GWT apps. For example I use lightbox which will not be used at the beginning of the app ,so i can i download the GWT generated html first to build home page and then load then js files later when required . I have configured these js files in module.gwt.xml On Feb 15, 7:22 pm, Tóth Imre tothi...@gmail.com wrote: I think 12 secs for 190 kb is too much even if you use a 512 kb/sec connection.

Re: Need to enable parallel download .
If the scripts can execute a function when they are finished loading, you can use the script injection technique. Basically, you create a script DOM element and attach it. The catch is that you won't know when the script is finished loading unless you wait for a function to be executed by the script. This patch to the gwt-google-apis project demonstrates how to do this in GWT: http://galgwt-reviews.appspot.com/3604/show On Mon, Feb 16, 2009 at 3:16 AM, Ghostcoder thanneer.ma...@gmail.com wrote: I have few JavaScripts (abt 35kb) getting downloaded at the beginning even thought it is used later in the app.Can i load javascript lazily with GWT apps.

Re: Need to enable parallel download .
You could try creating multiple modules and having some parts of the application load up a new GWT module. I don't know of any tutorials, sorry. There is a GWT feature under development called 'runAsync' that is meant to help developer split up code for just the kind of thing you're talking about. I don't think it made it into 1.6 however (which is just now being released). -Eric. On Sat, Feb 14, 2009 at 10:41 AM, Ghostcoder thanneer.ma...@gmail.com wrote: Thanks for the reply .
