The following SQL snippet shows a neat way to do queries when implementing paged results.
I have tested the snippet on MySQL 5 only.
SELECT SQL_COUNT ROWS *, tableName.id, tableName.someCol FROM tableName LIMIT 0,25;

PHP Boolean Rules
When converting to boolean, the following values are considered FALSE:
- the boolean FALSE itself
- the integer 0 (zero)
- the float 0.0 (zero)
- the empty string, and the string “0″
- an array with zero elements
- an object with zero member variables (PHP 4 only)
- the special type NULL (including unset variables)
- SimpleXML objects created from empty tags
Every other value is considered TRUE (including any resource).

'select':function(selected){ alert(selected.value); }
}
...
});
Node cannot be inserted at the specified point in the hierarchy
If you get the following error when developing with Ext JS 4:
“Node cannot be inserted at the specified point in the hierarchy”
Make sure your Panel IDs are unique.
In my case, I had 2 form panels both with the same ID that I was trying to render.
