Currently, I made a tool to rename view numbers (“Detail Number”) on a sheet based on their location on the sheet. Where this is breaking is the transactions. Im trying to do two transactions sequentially in Revit Python Shell. I also did this originally in dynamo, and that had a similar fail , so I know its something to do with transactions.
Transaction #1: Add a suffix (“-x”) to each detail number to ensure the new numbers won’t conflict (1 will be 1-x, 4 will be 4-x, etc)
Transaction #2: Change detail numbers with calculated new number based on viewport location (1-x will be 3, 4-x will be 2, etc)

Attached is the python file, but essentially what im trying to do is:
# <---- Make unique numbers
t = Transaction(doc, 'Rename Detail Numbers')
t.Start()
for i, viewport in enumerate(viewports):
setParam(viewport, "Detail Number",getParam(viewport,"Detail Number")+"x")
t.Commit()
# <---- Do the thang
t2 = Transaction(doc, 'Rename Detail Numbers')
t2.Start()
for i, viewport in enumerate(viewports):
setParam(viewport, "Detail Number",detailViewNumberData[i])
t2.Commit()
Attached is py file
So this issue actually had nothing to do with transactions or doc regeneration. I discovered (with some help :) ), that the problem lied in how I was setting/getting the parameter. "Detail Number", like a lot of parameters, has duplicate versions that share the same descriptive param Name in a viewport element.
Apparently the reason for this might be legacy issues, though im not sure. Thus, when I was trying to get/set detail number, it was somehow grabbing the incorrect read-only parameter occasionally, one that is called "VIEWER_DETAIL_NUMBER" as its builtIn Enumeration. The correct one is called "VIEWPORT_DETAIL_NUMBER". This was happening because I was trying to get the param just by passing the descriptive param name "Detail Number".Revising how i get/set parameters via builtIn enum resolved this issue.
