extension/jacextension/design/jacextension/templates/jacextension/plan.tpl and i put the same fecth but still fail. i add jacextension in my design.ini.append.php and I have a module called jacextension with a view called plan.
/jacextension/setting/design.ini.append.php
<?php /* #?ini charset="utf-8"? # transmit to eZ, to search for designs in jacextension
The template string you're looking for is plan/plan.tpl. You might wanna consider moving your extension templates to a subfolder so that they can't conflict, like /extension/jacextension/design/standard/templates/jacextension/plan/plan.tpl.
Note that the string above uses the standard design as opposed to your custom jacextension one. This is on purpose, as it will make the extension portable to any eZ Publish.
Thanks for reply, but this call don't work too with the structure /extension/jacextension/design/standard/templates/jacextension/plan/plan.tpl . I don't know why it doesn't work i desperate for this.
The last try looks correct, is the extension activated, is it configured to be an DesignExtension, did you clear cache (specifically template override cache)?
