I created a extjs4.1.1 application with sencha architect. Autocreate viewport (layout border), inside 2 panels.

I copied, the app.html to index html, placed the needed tags into index.html.

Using the:

PHP Code:
# sencha compile -classpath=ext-4.1.1a/src,app page --input-file index.html --output-page index-production.html 
command, I created a deployed version. When I point the index-production.html in chrome, I got the following error:
PHP Code:
Uncaught Error: [Ext.createByAliasCannot create an instance of unrecognized aliaslayout.border 
When I'm changing the viewport layout from border to fit, hbox, etc. then everything is good.
