| ETL: protected regions not working [message #877041] |

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?

That seems fine according to the book. In our case we use
[%=out.startPreserve("--", "--",entity.identifier + " Additional Descriptions", true)%]
[%=out.stopPreserve()%]
But I now recall I have a report of preserved regions being overwritten as in our case. Any one has any other ideas?

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.

Hi Louis. Thanks for your reply.

No, I have already tried that...
Is there any debug mode that can me help finding the problem?
BTW, do I have to set any option in the run configuration to be able to use protected regions?

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 :\ )
