Shared Posts Not Appearing on Profile Page Timeline
Design and Skin Customization
Yeah, it looks like the item_list.tpl file for the jrAciton module is setup for some different scenarios
The {foreach} loop on $_items is catering for 3 scenarios,
* if the variable $item.action_original_profile_url is set
* if the variable $item.action_text is set
* if the variable $item.action_data is set
So to understand why each section is used, you'd need to understand what each of those variables are and why they may or may not be set. The notes help:
* {* Shared Action *}
* {* Activity Updates *}
* {* Registered Module Action templates *}
So from those explanations I would assume, the first block fires if the action is one that has been on someone elses timeline, then shared to the current location. The second block fires if the action is one that was created when some module item was updated and the third fires when 'registered module action templates', not sure, would need some investigating.
