Re: Copied text stays in clipboard when it shouldn't

A very odd error! I've tried copying and pasting within Rel -- which works as expected -- and then copying and pasting within Visual Studio, Notepad, and Notepad++ whilst Rel runs in the background, which also all work as expected. What application are you pasting to? Perhaps there's some odd intera...

Re: Column heads for RVAs not treated right when names only selected

This appears to be correct, or at least how it's intended to display. The type of the RVA is shown graphically, rather than being written out as RELATION {...}

Re: TYPE inheritance implications

I know what Rel will do with the definitions of A and B, but how they should be considered within the TTM model I'm not sure I can answer. Hopefully, Hugh will see this and can answer. Alternatively, as this is more of a TTM question than a Rel question, perhaps it's worth asking on the email-based ...

Re: Unable to find most specific common supertype

That's helpful, and I'll try to provide a better solution. It's actually a limitation in how I've implemented the type inference, but it should be a semantic error rather than the fatal error it is now. At a minimum, I'll update it to be a semantic error in the next release. The solution/workaround ...

Re: Unable to find most specific common supertype

Could you post the expression or statement that causes the error?

I tried inserting the problem tuple into the Province relvar and it works.

Thanks!

Re: Incorrect display of a tuple with RVAs

Can you post a relation literal that exhibits this problem? E.g., turn "Display enhanced output" off and paste the result into a post.

Thanks!

Re: Column heads for RVAs not treated right when names only selected

Can you post a paste of a relation literal that exhibits this problem, such as the relation below with "Display enhanced output" turned off?

That will help me see exactly what's going on.

So far, I've not been able to duplicate this.

Re: Input nonappearance in output pane

Try checking "Preferences | Command line | Use an alternative output display to try to fix output problems." The standard output is actually hooking into the default Web browser. Depending on the version and type of default Web browser, it sometimes breaks, and the alternative output display will ge...

Re: edit functions greyed out mysteriously

Version 3.010 introduced menu equivalents for toolbar items, so it's likely that some interaction between the two causes this. Note that the Edit menu options only appear when the command-line -- with its toolbar edit options -- is active. Currently, only the command-line panel activates the Edit me...

Re: Can't return to Name+Type in rel.exe

I still haven't been able to replicate this.

However, it's a feature I use frequently, so I'll inevitably see it at some point and can hopefully trace back the steps to consistently repeat it, and thereby fix it.

Re: Rev query problems

Forgot to mention using Rel v.3.010. While working on the above problem query I received the following error in the log. I have no idea if it's related to the "null" errors I'm also getting.
