Display not updating
Hi,
I have a function that is used to process a set of data that is
returned from a server. This routine gets the date range for the data
returned and pops up a window for the used to enter the range that
they are interested in. The code will then go through the data and
draw a polyline on a map for the relevant set of data. This is a long
process and I wanted to display a progress bar on teh dialog to show
that the processing is happening. I am unable to get the progress bar
to update whilst the code is looping through the data.
Can anyone suggest a solution.

Re: GWT + Google Maps [ERROR] Unable to load module entry point class
I am also sufferring from this problem. My code was working perfectly well yesterday morning but then at around lunchtime it just stopped and the crash isn't anywhere in the code that I was modifying. Today I have tried going back to a backup of my source that was working on monday night and this now displays the same symptoms even though it worked perfectly when I did the backup. I have tried numerous things this morning, including creating a new project following the tutorial and not even this will work. Can someone please help.

Re: GWT + Google Maps [ERROR] Unable to load module entry point class
Hi, I have just discovered what the problem is after wasting about 8 hours looking into it. The API version in your script tag that contains the key will refer to v2 of the API. Until yesterday at about 12:30pm this mapped to v2.148 of the api. But it was then changed to map to v2.150 of the api and this is what appears to have caused the failures. The simple fix is to change v2 in the script tag to be v2.148. This should solve the problem. Cheers Gary On Mar 25, 10:15 am, nmadzharov nmadzha...@gmail.com wrote: Thanks for your reply.

Re: GWT + Google Maps [ERROR] Unable to load module entry point class
That is the exact error that I was seeing and the changing the script tag to script src=http://maps.google.com/maps? gwt=1amp;file=apiamp;v=2.148 / in the *.gwt.xml file solved the problem. It fixed both the sample code and my existing project that had stopped working yesterday Gary On Mar 25, 3:52 pm, nmadzharov nmadzha...@gmail.com wrote: i dont understand how it does cimpile the project successgully, i.e. it finds that module and validates it and then it says it can't load it.
