We found that our desktop GXT3 app actually works quite well on iPad and Android tablets except that buttons and clickables are too small and not touch friendly.

But instead of translating the...

In GXT 2, I used CheckBoxGroup to group many CheckBoxes in one field and had a custom validator to check that at least of the checkboxes is checked.

Where do I insert this code? I tried on Ext.application launch; it didn't work for me.

My understanding is: disableCaching is enabled (default) so the loader adds "_dc" param to dynamic loaded files. This causes Chrome to treat each load as new file thus losing the breakpoint.

I am...

I can't debug ST2 because breakpoints disappear when I reload the page.

Searched internet and found several mentions of ?breakpoint and Ext.Loader.setConfig({disableCaching: false});. But I...

How should I declare other dependencies that do not fall in one of the 5 categories (models, views, controllers, etc.)?

I think my problem is that I access index.html using file://, not http:// via a web server.

I can't find any API docs on com.extjs.gxt.charts on this page: http://www.sencha.com/gxtdocs/

markInvalid("message"); in validateValue() works

However tracing the source code I found out setSelection() performs validation before setting selections. To make matter worse, rawValue is always...

ListField has no setValidator method.

According to API, I override validateValue() and that works, but how do I set the error text?

I tried

beanModel.setData("label", wrappedBean.getLabel());
beanModel.setDisplayField("label");

Nevermind. I figured out.

How do I set the display field if I use BeanModel for my ListField store?

I tried field.setDisplayField("bean.label");, but got JavaScriptException: (TypeError): 'bean' is undefined.

The other differences I can tell between demo and my code are I am using a BeanModelReader, and that the grid is shown in a Window.
