Hello

We are using LLBLGen 2.5 Final (5. December 2007).

We use a custom TypeConverter to convert a field from an integer to a System.TimeSpan in the LLBLGen designer. Everything works fine - fetching, saving etc - as long as we don’t serialize an entity containing a TimeSpan field. The xml after a call to entity.WriteXml(…) also looks just fine:

<WorkItemWithProductInfoEntity Assembly="Test.DBLayer, Version=1.0.3373.25196, Culture=neutral, PublicKeyToken=null" Type="Test.DBLayer.EntityClasses.TestEntity">
  <Fields>
    <LengthInDays>
      <CurrentValue Type="System.TimeSpan">4.00:00:00</CurrentValue>
      <DbValue Type="System.TimeSpan">4.00:00:00</DbValue>
      <IsChanged>False</IsChanged>
      <IsNull>False</IsNull>
    </LengthInDays>
.. more xml

But when we read the entity with a call to entity.ReadXml(…) we get “'entity.LengthInDays' threw an exception of type 'System.InvalidCastException'”. Any idea why this happens?

Hi Olav,

This coud be realted to this old fix: http://llblgen.com/tinyforum/Messages.aspx?ThreadID=13468&StartAtMessage=0&#75914

Please update to the latest runtime library version (downloadable from the customer's area) and if possible download the full version. Then try again.

Thank you,

We updated to 2.6 (was time anyway ) - and now it works just fine.
