Just wonder if there are any known issues when using dots in Maple code attachment names?

Only issue so far that I can see is that error messages are split a bit strange.

I know that this is not really a question regarding core Maple package, but I am running into problems during the installation process.

After having upgraded Maple networktools as mentioned, I am unable to run the activation program due to an error.

"Java Virtual Machine Launcher: Error: Could not create the Java Virtual Machine."

I've never had that problem before in previous versions. There was no Java installed on the (virtual) server, so I installed the latest OpenJDK to check if that solved the problem.

Unfortunately it didn't.

Any hints would be appreciated.

Windows Server 2012R2

Don't know if this is a bug or just another proof of my incompetence, but I am struggling in storing values between sessions using DataTable components.

The problem seems to me to be related to nested tables, somehow.

I've made a little example showing the problem.

Quickly explained, you should do 2 runs to see the problem. The first run creates a matrix and a table, and stores the values in a DataTable cell. You shouldn't see any problems there.

Save the document and close it.

Then open the file once again, but just run the 2 commands in chapter 4. You should then see an error message.

My goal is to be able to save a nested variables with its values in a Datatable between sessions. The main variable and many of them below are tables, the last in the branch often string values or numbers with units.

Why is a more direct approach of defining a table now working and giving an indexed type, while the indirect approach is giving a table?

atable := table()

table( [ ] )``

(1)

a := table()

table( [ ] )

(2)

atable["a"] := a

a

(3)

atable["b"] := table()

table( [ ] )

(4)

whattype(atable["a"])

table

(5)

whattype(atable["b"])

indexed

(6)

NULL

There are a couple of warnings in the Maple Code Editor that are unneccessary. Those are valid parameters of in Maple functions.

Would it be possible to have those removed in future editions?
