[jira] Created: (VELTOOLS-128) LoopTool doesn't sync correctly
LoopTool doesn't sync correctly
-------------------------------
Key: VELTOOLS-128
URL: https://issues.apache.org/jira/browse/VELTOOLS-128
Project: Velocity Tools
Issue Type: Bug
Components: GenericTools
Affects Versions: 2.0
Environment: Velocity Tools 2.0, Velocity Engine 1.6.4
Reporter: Iain Miller
When using LoopTool, it doesn't appear to sync correctly, starting "one in" on the second list, and also missing the last value from the second list.
Running the example from the documentation, without the stop():
#set( $list = [1..7] )
#set( $others = [3..10] )
#foreach( $item in $loop.watch($list).sync($others, 'other') )
$item -> $loop.other
#end
produces:
1 -> 4
2 -> 5
3 -> 6
4 -> 7
5 -> 8
6 -> 9
7 -> $loop.other

[jira] Resolved: (VELTOOLS-128) LoopTool doesn't sync correctly
Posted by "Nathan Bubna (JIRA)" <de...@velocity.apache.org>.
[ https://issues.apache.org/jira/browse/VELTOOLS-128?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Nathan Bubna resolved VELTOOLS-128.
-----------------------------------
Fix Version/s: 2.0.x
2.x
Resolution: Fixed
Ok, i've mostly fixed these problems. I believe there are still some issues with last synced items in outer watched and synced loops when an inner loop has finished rendering, but i don't know that there's any reasonable way to fix those, at least not without undesirable side-effects. The reality is that LoopTool is attempting some fairly audacious stuff for a tool and can only support a certain level of complexity.
So all reading this who wish to do complex nesting, watching and syncing with LoopTool had best push their insanity out of their templates. Or ask me and i'll tell you some even... uh... "loopier" in-template solutions that just occured to me. :)
