so if we buy your product now (Developer edition, Site License), will we get an upgrade when you release the complete product ?

right now we are starting new project that requires an Oracle provider for EF4.

if possible, can you provide your release (or fix) schedule for this issue (generate DB from model)?

If you purchase dotConnect, you get a year subscription on the new builds.
As for the timeframe, we plan to release a new build this month.

Can you confirm that this issue will be solved in the next release this month?
Because I have a plan to start implement within 1-2 weeks.

Yes, we have already fixed the problem.
Anyway, there is a workaround.
You can manually set the MaxLength facet for the conceptual String properties in the model. This should be enough to overcome the probelm.

Thank you for the solution. I've try the workaround. It works well without any error but the script generated is for SQL not Oracle Database.

Have i did something wrong? Does the product support this feature?

Please make sure that you have chosen the Devart SSDLToOracle.tt (VS) DDL Generation Template in the model properties.
