Declaring objects of enum types within EOL scripts [message #531925]

Hi,
I have a metamodel containing a class:
class Table extends BlockElement {
attr ColourType backgroundColourName = "WHITE";
val TableCaption caption;
val TableSection[?] head;
val TableSection[?] body;
val TableSection[?] foot;
}
Where:
enum ColourType {
WHITE = 0;
RED = 1;
BLUE = 2;
YELLOW = 3;
ORANGE = 4;
GREEN = 5;
LIMEGREEN = 6;
LIGHTBLUE = 7;
LIGHTSLATEGRAY = 8;
}

I call an operation in an EOL script from ETL (which is run from an Ant
workflow) and want to declare a colour value, e.g.
var ok : Report!ColourType := Report!ColourType#LIMEGREEN;

However, this returns an error 'Report!ColourType not found'. Although I
can do this within the body of an operation:
<snip>
if (match.isMatching()) {
for (row in table.body.row) {
row.paintContents(Report!ColourType#LIMEGREEN);
}
} else {
for (row in table.body.row) {
row.paintContents(Report!ColourType#RED);
}
}
</snip>

So, clearly, the type is being resolved. Is this a problem with my
syntax? How can I declare the variable 'ok' (above) correctly?

Regards
Chris

Hi,
I intended to show the following code fragment (which runs successfully):
<snip>
if (match.isMatching()) {
for (row in table.body.row) {
row.backgroundColourName := Report!ColourType#LIMEGREEN;
}
} else {
for (row in table.body.row) {
row.backgroundColourName := Report!ColourType#RED;
}
}
</snip>

Chris

Hi Chris,

You've hit https://bugs.eclipse.org/bugs/show_bug.cgi?id=286412 I'm
afraid. Enumerations are not valid EOL types so I'm afraid you'll have
to use the Any workaround (or omit the type altogether) until we get
this fixed.

Cheers,
Dimitris

Hi Dimitris,
At least it wasn't me ... this time ;)

Thanks for your help.
Best Wishes
