I'm trying to use protected regions with ETL. So, I put the following code in the template:
[%=out.preserve("/*", "*/", name+"-Prop", true," //TODO")%]
This generates the following code:
/* protected region Local-Prop on begin */
//TODO
/* protected region Local-Prop end */
which I think is correct.
Then I changed the previous code to this:
/* protected region Local-Prop on begin */
test();
/* protected region Local-Prop end */
I was hopping that after generating the code again I was going to keep the 'test();', but that content is lost, and it is replaced with '//TODO'.
Am I doing anything wrong? Is there anything else I need to do, besides using the "preserve" method?

Hi Rui Carlos,
Rui Carlos Gonçalves wrote on Sun, 27 May 2012 13:55I've already tried many different ways (preserve/startPreserve, different ids, different comments ), and it's not working :\
I'm not using any special character in the id.
I'm sorry to hear that you're having problems with protected regions. I think this might be related to the bug that Martin mentions. Can you try again without the hyphen in the identifier? So, for example:
[%=out.preserve("/*", "*/", name+"Prop", true," //TODO")%]
I believe that, in the latest stable release of Epsilon, identifiers could only contain word characters (i.e. [a-zA-Z_0-9]). Alternatively, you can try updating to the latest interim release of Epsilon, which contains the fix for this bug and should work with your existing code.
Hope this helps,
Louis.

I think I've solved the problem...
I was calling the template directly in a Run Configuration and it was not working.
Now I'm using "TemplateFactory.load"/"generate" methods instead of calling the template directly, and it seems to be working 
Not sure if this is the expected behavior, but it solved the problem.
PS: Louis, if this is still a bug (i.e., if protected regions are supposed to work even without using the "TemplateFactory.load"/"generate"), let me know, and I'll create the bug report. (I haven't done it yet, as creating a minimal example, with metamodels and editor, takes some time :\ )

Sorry, it's working. It was my fault.
I had forgotten adding [% out.setContentType("Java"); %]
Best,
Víctor

is this issue solved?
I'm using latest interim version of Epsilon in Oxygen.
I use the sample code from the book:
// protected region anId on begin
System.out.println(foo);
// protected region anId end
If I use that code directly it doesn't work.
If I create a EGL file and called it with generate works on the new target specified in the generate method.
If I use process it doesn't work.
Are there any requirements for preserved regions to work?
Best,
Víctor
