criteria -> sql translation problem with SqlDataSource

[csillag]

I have a DS with a boolean field (among other things.)
When I create a ResultSet with this DS, and run a query with this criteria:

    criteria:{
        FLAG_CLOSED:true
    },

The allowing SQL query is generated:

SELECT ... WHERE ... (FLAG_CLOSED='true')

Please note, that the FLAG_CLOSED field, which is a boolean field, gets a "true" string literal. However, the database contains "True" values (uppercase), so this does not find anything.

--------------------------------

Is this intended?

(This is with SmartGWT 2.1 Power.)

The same thing happens when I send this query from a ListGrid (instead of a ResultSet), using the filter row to set the boolean true value (ie. using the checkbox).

As you can see, the boolean true filter criterion gets translated to "true", unstead of "True".

[csillag]

Turns out the problem was with the database: the collation of one field was set to utf8_bin instead of utf8_general_ci, so "true" did not match "True".

(No idea how this one field got messed up, though.)
