Arg_InvalidCastException

[Vic]

Hi,

I cannot reproduce this exception though a few of our users had came across this error, could someone please shed some light on this.

We are using Q3 2010 - v2010.3.1110.1040 and if it helps we are using the HTML format provider.

Thanks,
Vic

Hello Vic,

Unfortunately we are not sure about the exact reason for this problem. The exception is thrown from a Silvelirght routine that we are not able to debug or see what might have caused the problem. The good news is that we changed the problematic code a bit at our side and in the new version this problem might be resolved, however we are not able to confirm this 100%.
Please, try the new version if you can and see if it this problem reappears. If the problem persists, to further review this issue, we would more information about the scenario. For instance, you can send us a sample document that produses the problems and any steps to help us try to replicate this at our side.

Kind regards,
Mike

Hi Mike,

It has been determined that it happens when a user selects a section and then types over it w/o clicking delete/backspace first.

We can't upgrade to the new version w/o a lot of testing, we use about 60% of your Silverlight controls. Was hoping for a quick fix.

Thanks,
Vic

Hi Vic,

We could try giving you more details about the problem and probably a solution for it. However as Mike said we will need a sample document that produces the problems and the steps to help us try to replicate this at our side. 

Provided the above we will be able to try assist you resolving your problem.
