bug? Creating default object from empty value

[ophian]

Smarty version 3.1.30-dev/72
(That was definitely working prior to some of the latest commits, Uwe.)

Fatal error: Uncaught exception 'ErrorException' with message 'Warning: Creating default object from empty value' in [... tpl files]\*_1.file.show_plugins.fnc.tpl.php:50 Stack trace: #0 [... tpl files]*_1.file.show_plugins.fnc.tpl.php(50): errorToExceptionHandler(2, 'Creating defaul...', '[... path]', 50, Array) #1 [... libs]\Smarty\libs\sysplugins\smarty_template_resource_base.php(128): content_5756722242d301_28010074(Object(Smarty_Internal_Template)) #2 [... libs]\Smarty\libs\sysplugins\smarty_template_compiled.php(162): Smarty_Template_Resource_Base->getRenderedTemplateCode(Object(Smarty_Internal_Template)) #3 [... libs]\Smarty\libs\sysplugins\smarty_internal_te in

Sadly (#3)-trace breaks here, while path strings were too long, I assume.

Edit: line 50 in the compiled file is $_smarty_tpl->tpl_vars['plugin_data']->index = -1;
Edit2: temporary disable this line `#$_smarty_tpl->tpl_vars['plugin_data']->index = -1; helps!

Thanks, @uwetews

@uwetews I just saw another bug report in issue #239.
I think that this might be related to what I have caught, but in difference I need to add here, that my (sub)array is not empty. It has named keys.

Edit: I recognized it is an empty array as well, looping in the first run, which we catch with {if !is_array($array)}.
