I am debugging an activity made about a year ago and there is a line inside of a loop that calls "FlushDeclarativePage". As parameter, it expects the page's name. So the current parameter is "D_MyFiles". 

My objective is to flush D_MyFiles[ Filename: "MyFileName"]

problem is that on the second iteration of the loop, the instance of D_MyFiles is loaded from cache. Which is not what I want. 

It began to work when I used 'Page-Remove: D_MyFiles'. 

Although, I am confused as to why FlushDeclarativePage did not work. My understanding is that all data pages are also declarative pages. 

Anybody know why this is the case? 

Extra information: 

The D_MyFiles data page is set on Thread level and "Reload once per interaction" (in case this matters).
