NHibernate.NonUniqueObjectException inserting a unique class , but it says it's already in the session

Okay,

So I'm inserting new records, Retreived by ADO and inserting with Nhibernate, cause that's how it done here at JCDC. I'm getting NHibernate.NonUniqueObjectException for no discernible reason.





Well, there is a reason. Nhibernate has lots of weird rules about the map it uses to keep track of changes to the state before .commit is called. When you're updating with objects not retrieved by NHibernate, sometimes it gets squirrely. Wish I had better details but there it is, look at the link above and follow the link there to Aiendes explanation for more details (not better really just more).

But here is how I fixed it, I got ahold of the NH session object and merged the object i'm inserting before I inserted it, and voilia, it stopped throwing an exception.





public void InsertDedHist( DedHistCV userInput )
{

 if( IdList.Contains( userInput ) )
 {

     throw new Exception("BUG FOUND!!!!");
 }

 else 
 { 
     IdList.Add( userInput ); 
  }
　

 try 
 { 
     Trace.WriteLine("");
     DedHistEO temp = new DedHistEO();
     temp.InjectFrom( userInput );
     DedHistEO mergedEo = (DedHistEO)JcdcDb.GetSession().Merge( temp );
     DedHistEO userInput2 = JcdcDb.Insert<DedHistEO>( mergedEo );
 }

 catch ( Exception ex )
 {

  throw;
 }
}

Memory leak in creating RLDC Reports in .Net 4.0

There is a huge memory leak in Microsofts LocalReport implementation in .Net 4.0

The work around to make it a small memory leak is here,
and in the comments is how to make it go away...


Though I'll warn you it's a pain.



http://stackoverflow.com/questions/6220915/very-high-memory-usage-in-net-4-0

Are you having a memory leak because of Strucutre map?

So here's the situation....


(My parents went away for a weeks vacation...(Soory, can't help myself, child of the 80s...))



Running a winforms app using a Library that has structure map all through it, and it uses ObjectFactory directly instead of IContainer....


So we get memory leaks that we can't get rid of as Structure map is hanging on to instances of the objects so they can't be garbage collected...



Here's the quick hack to fix in,



Since what I'm doing is in a loop, at the bottom of the loop construct I just type:



// strucutre map memory leak hack, works okay i guess, it's slower as expected - EWB
ObjectFactory.ResetDefaults();



and it flushes all the objects out of Structure map...

Of course it's slower because all the objects get re init-ed in each loop, but the memory
got tons better...

Also note that in an upcoming release,



ObjectFactory.ResetDefaults();



will get changed to



ObjectFactory.Reset();

The parameter of type 61 did not have a valid value

The parameter of type 61 did not have a valid value

This is an error from the Sybade Database.

It means that a variable of type 61 (Date) does not have a valid value.

This is ususally caused by your Date time not being Nullable in your EO or you CV and because
Microsoft and Sybase have different Epochs, or Minimum Dates values.

Microsofts EPOCH for a DateTime is: 00:00:00.0000000, January 1, 0001
and Sybases depends on the exat type in your DB see the chart here:
http://infocenter.sybase.com/help/index.jsp?topic=/com.sybase.infocenter.dc35400.1550/html/osref/osref281.htm

But in essence here is what happens.

In the DB the Date is null,
In your EO the dateTime is not nullable
Net converts the null to DateTime.Min (01/01/01)
during an update this value is smaller than the allowed (for us ususally 01/01/1900)

Best fix, it to change the Datetimes in your EO & CV toall  be nullable, OR to use a CV that does not contain any of the date fields for updating, and let JCDCHelper deal with it..

See here for the codes of all Sybase datatypes : http://infocenter.sybase.com/help/index.jsp?topic=/com.sybase.help.ase_15.0.tables/html/tables/tables69.htm

An error occurred during local report processing. ->An error occurred during local report processing. ->ClassName

So I was Moving an RDLC Report from one applicaiton to another,

I was getting this excpetion..

(summary of the messages of the exception and it's inner exceptions:
An error occurred during local report processing. --->
 An error has occurred during report processing. --->
  StudTarReportCV

Where StudTarReportCV is the name of the class I'm passign in a list of with the reprot Data.

Not alot to go on, basically it says "Something Bad Happned with the CV class"

The Actual Problem was that the DataSet Name I was Passing it didnt' match the one defined in the RDLC.

RDLC-> StudTarReportCV
PassedToReportViewer->EFolderReportGenerator3G_CV_StudTarReportCV


So how I fixed it was to modify the XML in thie RDLC file so that the dataSet Definition matched the value i was passing in:

<DataSetName>EFolderReportGenerator3G_CV_StudTarReportCV</DataSetName>

and then modified the use of the data set in the Tablix to match there:

<DataSet Name="EFolderReportGenerator3G_CV_StudTarReportCV">
Voilia, it's all working now...Full Text of Exception, incase anyone else runs into it:

Exception in StudentTar Ex = Microsoft.Reporting.WinForms.LocalProcessingException: An error occurred during local report processing. ---> Microsoft.ReportingServices.ReportProcessing.ProcessingAbortedException: An error has occurred during report processing. ---> Microsoft.ReportingServices.ReportProcessing.ReportProcessingException: StudTarReportCV

JCDCHelper code to return one column of one row cleanly

lots of us when returning one column, return an object and then have to cast that to a <T>

This fixes that to work more cleanly.

public T JcdcAdoGetOneColumn<T>(string mainSql){

 object answer;
 using (IAdoHelper ado = ObjectFactory.GetNamedInstance<IAdoHelper>("JCDC")) {

  answer = ado.GetOneColumn<T>(mainSql, null); }


 return ConvertObjectToT<T>( answer );}

  private T ConvertObjectToT<T>( object answer )
{

 // handle the cast for both primitive and non primitive types - EWB if ( answer is T ) {

  return ( T ) answer; }

 else {
 try {
  return ( T ) Convert.ChangeType( answer, typeof ( T ) ); }

 catch ( InvalidCastException ) {

  return default( T ); }
}
