LinkTool.addRequestParams methods are difficult to use from VTL due to their
String[] parameter type
----------------------------------------------------------------------------------------------------
Key: VELTOOLS-149
URL: https://issues.apache.org/jira/browse/VELTOOLS-149
Project: Velocity Tools
Issue Type: Bug
Affects Versions: 2.0
Environment: Velocity 1.7, Velocity-Tools 2.0
Reporter: Christopher Schultz
Priority: Minor
If I call addRequestParams() with no argument, things work as expect. On the
other hand, this does not work:
#set($ignoreList = ['foo'])
$link.relative('/bar').addRequestParamsExcept($ignoreList)
I get an invalid reference log message and the above "$link..." text is
rendered as written instead of evaluating successfully.
The problem is that the ignoreList is a List and it needs to be String[].
Velocity will auto-convert Lists into Object[] if appropriate, but the
resulting object type is Object[] and not String[].
There does not appear to be a way to create a String[] from a Velocity
template, so using addRequestParams and the other, similar methods will be very
difficult to use with an argument.
LinkTool.addRequestParams and friends should be modified to accept Object[]
arguments.
