Designer exited with an error null, lost all the work done
When I am working with Sencha designer with trail mode, I lost all the work done by me, when an error caught by the designer. Pasting scree shot for ready reference
Please update to the latest build of Designer (311).
This will allow you to ignore errors that occur and is also far more stable.
From where I can download this build, it is always downloading version 1.2.2, is it new build automatically added to the same version?
You can download the beta of Sencha Designer 2.x from here:
