Re: [Gwt-openlayers-users] Google Maps Issue

[Edwin C. <com...@gm...>]

Hi Abdelhadi,

With respect to issue 1. Do you see that in a plain GWT application? And is
it across browsers?

We have a problem like you are describing when using Ext-GWT, where WMS
layers only load in a small corner of the map, until resize. This happens
only in Firefox for us. In Firefox 3.5 the map is completely gone. We do not
experience this problems in a plain GWT app and it seems to have something
to do with the lifecycle of Ext-GWT components (they only get a size when
rendered if I am correct).

Greetings,
Edwin
