Java Component using validateStandard and SystemDatabase fails to incr cntr

Question

I based my filter on the Dynamic Prefix, and code I found in this forum. I have a vew in my System database that I want to validate a field against on checkin, instead of loading 50K values into a combobox. The problem is that when the routine runs and the emp_num is valid (routine succeeds), the counters table is not incremented and the next check-in fails? Any help appreciated. The code for the java component is below:
package mypackage.ucm;
import intradoc.common.ExecutionContext;
import intradoc.common.ServiceException;
import intradoc.common.SystemUtils;
import intradoc.data.DataBinder;
import intradoc.data.DataException;
import intradoc.data.DataResultSet;
import intradoc.data.ResultSet;
import intradoc.data.Workspace;
import intradoc.provider.Provider;
import intradoc.provider.Providers;
import intradoc.shared.FilterImplementor;
import intradoc.util.IdcMessage;
/* Setup in hda fild to use validateStandard
* validateStandard
* validateCheckinDate
* From Bex's book setReturnValue("true");  - Didn't help
public class EmployeeCheckinFilter implements FilterImplementor {
  public int doFilter(Workspace ws, DataBinder binder, ExecutionContext cxt)
      throws DataException, ServiceException {
    String value = "-1";
    String xEMP_NUM ="";
    String SQL = "";
    String ResultSetName = "XEMPNUMCOUNT";
    int ivalue=0;
    DataResultSet result = null;
    DataException error = null;
    ResultSet temp = null;
    SystemUtils.trace("system", "Starting doFilter for EmployeeCheckinValidation");
    // Display the binder
    // System.out.println(binder);
    xEMP_NUM = binder.getLocal("xEMP_NUM");
    SystemUtils.trace("system", "xEMP_NUM=" + xEMP_NUM);
    // Only run valiation is
    if (xEMP_NUM != null && xEMP_NUM.length() > 0) {
      SQL = "select count(*) counter from dcsdemployees where emp_num = "
        + xEMP_NUM.trim();
      SystemUtils.trace("system", "SQL=" + SQL);
      if (ws == null) {
        SystemUtils.trace("system", "ws is null, getting ws from call to getSystemWorkspace()");
        ws = getSystemWorkspace();
      SystemUtils.trace("system", "try-catch block to get ResultSet from SQL");
      try {
        temp = ws.createResultSetSQL(SQL);
        result = new DataResultSet();
        result.copy(temp);
        // Makes results avilable for other Java methods or IdocScript templates.
        // binder.addResultSet(ResultSetName,result);  // Don't want this available
      } catch (DataException de) {
        error = de;
      } finally {
        ws.releaseConnection();
      try {
        result.first();
        value = result.getStringValue(0);
        SystemUtils.trace("system", "value(getStringValue(0)) = " + value);
        ivalue = Integer.parseInt(value);
        SystemUtils.trace("system", "ivalue=" + ivalue);
      } catch (NumberFormatException nfe) {
        SystemUtils.trace("system", "nfe.getMessage()=" + nfe.getMessage());
      // Can't find a match, throw an exception
      if (ivalue == 0) {
        SystemUtils.trace("system", "Throw error since xEMP_NUM is not in the dcsdemployees table");
        throw new ServiceException("xEMP_NUM was not found in the database!");
      if (error != null) {
        SystemUtils.trace("system", "Throw error since error condition exists.");
        throw error;
    SystemUtils.trace("system", "Ending doFilter for EmployeeCheckinValidation");
    cxt.setReturnValue("true");
    return CONTINUE;
  public Workspace getSystemWorkspace() {
    Workspace workspace = null;
    Provider wsProvider = Providers.getProvider("SystemDatabase");
    if (wsProvider != null) {
      workspace = (Workspace)wsProvider.getProvider();
    return workspace;
}

Hey klee,
My guess at the cause of the issue is:
finally {
ws.releaseConnection();
You don't need to release the connection in a validate Standard filter since the checkin service will release the connection when it completes. Since the connection is being manually released the code that executes after the validateStandard does not have a connection to the DB and can't increment the counter. In fact I'm surprised you aren't getting an exception.
Hope that helps,
