Unhandled exception opening project

[gch...@gmail.com]

Hi,

I tried to open a ywriter project in ywSynch and got an unhandled exception: object reference not set to an instance of an object.

Can anyone help?

Details:

See the end of this message for details on invoking 

just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************

To enable just-in-time (JIT) debugging, the .config file for this

application or computer (machine.config) must have the

jitDebugging value set in the system.windows.forms section.

The application must also be compiled with debugging

enabled.

For example:

<configuration>

    <system.windows.forms jitDebugging="true" />

</configuration>

When JIT debugging is enabled, any unhandled exception

will be sent to the JIT debugger registered on the computer

rather than be handled by this dialog box.

I'll try and have a look at it later. I've been caught out a couple of times when Simon seems to have made items in the xml of the project file optional that used to always be there, so it might be something like that.

Could you send me a copy (to yws...@babbacom.com) of the .yw5 file that you are trying to open? It would make it a lot easier to track down the problem.

Actually, I think I have found the problem already. I think you have a chapter without any scenes in it. ywsynch isn't able to cope with that at the moment. I'll put in a fix for it, but for now (assuming that's what it is) just make sure that every chapter has at least one scene in it (an empty scene, even one marked unused, is fine).

Thanks for the quick response. I do have chapters without scenes. I'll try your suggestion and let you know if there are any problems.
