Juan,
Yes, more information would be helpful. Does your grid have where parameters defined? If yes, what are they? Did you add some custom code? Please provide us with full stack trace of the exception.
Regards,
Ignat.

Hello Ignat,
The sample project is at www.htmlspider.com.br/downloads/sample.zip
No I didn't define where parameters, and I did not add any custom code.
The code is as the generated by the builder. I have just deleted some
unwanted colums from the grid, that should be the cause of the problem.
Thanks for your help.

If you have an EditableGrid and use CheckBox then there is a known problem with the MVC data model. A patch from CCS was sent to me and this fixed the problem.

Juan,
Your usuario_list page worked for me without any NullPointerExcpetion. But I had to replace your SQL:
SELECT NOME, EMAIL, LOGIN, SENHA, NIVEL_ADMINISTRATIVO, NIVEL_CADASTROS, NIVEL_CONTABILIDADE, NIVEL_CONTAS_PAGAR, NIVEL_CONTAS_RECEBER, NIVEL_CONTAS_CORRENTES, NIVEL_ORDEM_TRABALHO, NIVEL_ATIVO_FIXO, NIVEL_FATURAMENTO, NIVEL_PRODUCAO, NIVEL_CONTRATOS, NIVEL_COMPRAS FROM usuario
wiht the new one:
SELECT * FROM usuario
Because NIVEL_ADMINISTRATIVO column doesn't exist in usuario table definition.
Regards,
Ignat.

Hello Anton,
It isn't an editable grid. Thanks for the information.

Hello Ignat,
The field NIVEL_ADMINISTRATIVO was added later to the table.
Unfortunately it isn't the problem. It is istill not working here.
May be it?s a Tomcat configuration ...
Thanks.

Hi Juan!

Of course 404. Why do you publish to "C:\jtech\Tomcat 4.1\webapps\erp\adm" upacked and then expect it appear at http://localhost:8080/erp/adm? usuario_list.jsp is at doc root. So if you configured Tomcat context for that URL should be "http://localhost:8080/your_context/usuario_list.jsp".
To start with, make it simple first. Publish to "C:\jtech\Tomcat 4.1\webapps" as war file and "Server URL" set to "http://localhost:8080/administrador".
Regards,
Ignat.

Build as a non-war distribution and if your error goes back to the line 37 of the AbstractProcessor.java:
param.setValue(((Control)row.get(param.getSourceName())).getValue());
then the problem is with null being returned from param.getSourceName())
This routes back to the CCS IDE version of 'cut and paste of a CCS control' where you cut and paste BETWEEN grids!
It may come as a 'surprise' when, for example, THE SORT COLUMNS have the wrong data field settings. This can be caused by a CCS IDE control 'cut and paste' between two different grids. The NullPointerException may NOT be in the row of data but in the column sort settings!
I find it extremely useful to build as a non-war distribution so that I can trace back through the code in a CCSBuild source sub-directory.
Be careful though as the source file generator pattern used by CCS does NOT produce 100% true and accurate CCS source .java files which marry to .class files found in a war-distribution. This is a known problem. It is however extremely useful to have reference to the .java files - if only to improve one's knowledge of the CCS MVC design pattern.

wiht the new one:
SELECT * FROM usuario
Because NIVEL_ADMINISTRATIVO column doesn't exist in usuario table definition.
And also, where is the column for the link's href source parameter USUARIO_ID ?
With no column USUARIO_ID data being pulled from the data file then the link can not function. This is why the 'Select *' works - assuming USUARIO_ID is actually the PK column for the table.

What kind of ODBC data source do you use ?
System,User или File DSN?
Make sure that there are no data sources with the same name but
of different type.
