IMPORTANT ANNOUNCEMENT

Due to the uncertain status of the Flyspray project, lack of new releases and moving the code repository to Github, we decided to shutdown this issue tracker by the end of January 2011. From that date, the bugs should be reported directly in Github project repositories.

List of repositories:

Open Power Template 2.x family

PLEASE PROVIDE THE TEMPLATES AND/OR PHP CODE IN THE TASK DESCRIPTION (Not URL-s to them). THAT ALLOWS US TO REPRODUCE THE PROBLEM! OTHERWISE WE ARE NOT ABLE TO HELP YOU!

Remember to hide all the security-related pieces of code from the task description, like passwords, server paths etc. for your own safety. Once we close the task, we cannot edit it anymore!

I haven't managed to reproduce the bug. My test script gives a valid exception:

~~~~
Unexpected token: OP_CURLY_BRACKET ({) in expression {$entry::link

Opt_Expression_Exception
~~~~

Opt_CompilerLocked_Exception is thrown in only one place in the script - at the attept to compile two templates at the same time with the same compiler instance.

~~~~
// We cannot compile two templates at the same time
if(!is_null($this->_template))
{
throw new Opt_CompilerLocked_Exception($filename, $this->_template);
}
~~~~

The problem may lie in the fact that an exception was generated earlier by the compiler and did not reset the compiler state properly. As I noticed, this was possible, because the very variable `$this->_template` was not unset during the compiler exception handling. So, your problem was not caused directly by the invalid syntax in the template, but rather by this or the next template compilation.
