Troubleshooting
===============

Controller Issues
-----------------

Getting errors such as Cannot redeclare drawmenu (previously declared...)
The problem is most likely that you called a printError() function, or something which started
the theme output, and did not return. Then another part of the program called the theme output again.

Theme output already started
----------------------------

This gets printed when the theme->render() function is being called a second time. Typically this will be related
to a print_error() call and where the controller does not immediately return, but rather continues on and subsequently
calls theme->render(). Look for Form->init() statements that do not return on error.

Calendar popup issues
---------------------

When a date input field is at the bottom of a page, the calendar tends to pop-up at the top of the page. Here is some code which
should correct the problem::

	$('#date').click(function() {
		var top = parseInt($(this).position().top);
		$('.DynarchCalendar-topCont').css({'top': top + 20});
		window.scrollTo(0, document.body.scrollHeight);
	});

Logging Errors
--------------

Use the CodeIgniter function log_message() to write to the daily error log. Here's an example:

``log_message('error', "Could not open '$cssfile' for writing.");``
