This thread is related to the other one but I give it a separate thread to make the question more apparent.

I have a data source with multiple operationBinding's. It has been working well until I add one more operationBinding with skipRowCount set to true.
The first operationBinding (with Id="RsUseQueryNonProgressive") worked perfectly, but the second operationBinding (with Id="RsUseQuerySkipRowCount") did not work.
First of all, I noticed that even I had specified skipRowCount="true", I still saw that SmartGWT issued a counting query.
And then the query also ignored the tableClause -- it should have say "from nara_db.rs358223955 as env" but it didn't -- it just said "from env", which is wrong and caused an SQL error of "com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'dw_db.env' doesn't exist"
Below is the debug log I obtained.
To show why the above was wrong, I am also showing the debug log for the other operationBinding that worked well. For this one, the equivalent debug log was:
