Error with extends Runbasebatch class .. a possible workaround …

Sometimes despite implementation of BOF Framework you could find to use the old Runbasebatch class (with implementation) and your implementation works fine during normal client but when you decide to run on batch obtain the following result

Microsoft.Dynamics.Ax.Xpp.ErrorException: Exception of type ‘Microsoft.Dynamics.Ax.Xpp.ErrorException’ was thrown.
at Microsoft.Dynamics.Ax.MSIL.Interop.throwException(Int32 ExceptionValue)

the best way it’s follow the suggestion of best developer and try to recompile / do incremental CIL and FULL CIL and so on

In some cases I solve change in the class declaration the parameter of version. This mean that you must change name of your internal variables but I see that sometimes works. See for information the example below

Original

class myclass extends RunBaseBatch
{

str htmlTitle;
str htmlBody;
str htmlTile;
QueryRun queryRun;
Email eMailTo;
DialogField df_eMailTo;

container ListNotified;
container ListTableField;

#define.CurrentVersion(1)
#define.Version1(1)
#localmacro.ContainerList
eMailTo
#endmacro
}

New

class myclass extends RunBaseBatch
{

str htmlTitle;
str htmlBody;
str htmlTile;
QueryRun queryRun;
Email eMailRecipientTo;
DialogField df_eMailTo;

container ListNotified;
container ListTableField;

#define.CurrentVersion(2)
#define.Version1(2)
#localmacro.Recipient
eMailRecipientTo
#endmacro
}

Obviuosly you must realign pack and unpack methods and where the variable is used after recompile anyway all (with final incremental CIL).

Bye.
