Adding an element to a diagram hangs EA and breaks the diagram

[Uffe]

Hi all,


Got a bit of a problem.

I've got a SQL Server project with a modelling team working away. Certain elements, however, appear to be broken.

If a broken element is added to a diagram, EA hangs and has to be killed.

On restart, I can verify in the database that the element has been added to the diagram; however, if I try to open said diagram, EA hangs and has to be killed.

This occurs even in a fresh empty diagram.

The only thing I can see that's odd in t_diagramobjects is that Sequence = 999999, and ObjectStyle only contains the DUID -- no colour or font properties, or anything else.

This is consistent for certain elements. I haven't investigated the elements themselves just yet, but does anyone recognize this? We're on 15.0.1512.

Nailed it.

The element name ends with a non-breaking space, which causes EA to hang.

EA hangs if you create an element with such a name in a diagram, or if you drag an element with such a name onto a diagram.
In either case, the element is created / added to the diagram, but if you open the diagram again (after a restart) EA will hang again.
So it's the diagram rendering that's at issue, not element or diagram object creation.

Non-breaking space at the beginning of, or in the middle of, an element name do not cause this behaviour.

EA displays non-break spaces as whitespace, but you can check whether a string contains a non-breaking space by pasting it into Word and switching on formatting symbols; it is shown as a degree symbol.

Reported.

No, but it feels like something that might get solved by the project integrity check.

Tried with the non-breaking space. Worked with no issue.

Welp, not in 1512 on SQL Server. It was definitely that, removing the offending character resolved the issue.

I once had a similar issue that happened after pasting text from a pdf into the notes field.

The text had a curly backtick (something looking similar to this: `) and that made EA crash hard upon saving the notes.

I used 15.1.1526 with EAP. Sorry, don't have a SQL server installed right now.
