I tried to add a condition to QWEB template "ControlPanel" to show a field which is project_id.description.
<t t-extend="ControlPanel">
<t t-jquery="div.container-fluid" t-operation="after">
<t t-if="widget.field_manager.dataset._model.name == 'project.task'">
<div><field name="project_id.description"/></div>
</t>
</t>
</t>
This doesn't work
