[jira] Created: (VELOCITY-538) Cannot add objects as values in Map
creation unless last entry is quoted
Cannot add objects as values in Map creation unless last entry is quoted
------------------------------------------------------------------------
Key: VELOCITY-538
URL: https://issues.apache.org/jira/browse/VELOCITY-538
Project: Velocity
Issue Type: Bug
Components: Engine
Affects Versions: 1.5
Environment: Windows XP Service pack 2, Sun JVM 1.5.0.11
Reporter: Asmodean
Priority: Minor
When creating a Map using the velocity 1.5 syntax ({key:value,...}) it seems I can only add objects (except Strings) as map values if the last map entry is quoted. The following (where $object is put into context before, of course) will produce a parse exception:
#set ($map = {"key": $object})
Where the following will not:
#set ($map = {"key": $object, "anotherkey":"anothervalue"})
The "anotherkey": "anothervalue" entry does the trick in the form of "":"" as well, but something is up here. OR this is a map creation "flaw" not documented. Using the following will of course not get the desired result:
#set ($map = {"key": "$object"})
since velocity will evaluate the $object reference and use its .toString() (where what you wanted to do was probably to add the actual object).
Would appreciate comments that could indicate if my thinking here is flawed or if it actually is a bug.

[jira] Commented: (VELOCITY-538) Cannot add objects as values in
Map creation unless last entry is quoted

Will Glass-Husain commented on VELOCITY-538:
--------------------------------------------
More detail. The problem is the } character right after the $object.
This doesn't work (parse error)
#set ($map = {"key": $object})
and this does (note the spacing)
#set ($map = {"key": $object })
