Hi all,
I am trying to generate a preserved region from an EGL template.
myTemplate.egl:
[%
@template
operation MyObject myOperation() {
%][%=out.startPreserve("//", "", "myRegion", true) %]
blah
[%= out.stopPreserve() %][%
}
%]
myFile.egl:
[%
import "myTemplate.egl"
This is my file
[%= myObject.myOperation() %]
More of my file
%]
But the above example returns a NullPointerException:
Error encountered whilst processing template. (generate-files.eol@21:14)
Cause: Internal error: Internal error: Internal error: Internal error: java.lang.NullPointerException

...and so on...
When looking around with the debugger it seems that OutputBuffer does have 'context' set, resulting in the NPE when an instance method of 'context' is called.
Am I doing something wrong? Or is it not possible to create a protected region from a EGL @template operation?
