Good morning!
I'm trying to move a simple script from XWiki 1.0 Syntax to 2.0 one. It includes this
lines with which I can easily use SQL to retrieve pages and present a list of URLs to
reach those pages:
db2 = Sql.newInstance("jdbc:mysql://hostname/schema", "ROuser",
"readonly", "com.mysql.jdbc.Driver")
List areas = db2.rows('select...
println areas.collect{"<a
href='../XWiki/${it.XWD_NAME}'>${it.XWD_TITLE}</a>"}.join("<br>")

For instance, these alternatives failed giving a Failed to execute the [groovy] macro
error message; all of them pointed to the first character of the nested html macro as
the>>> reason for the failure:

href='../XWiki/${it.XWD_NAME}'>${it.XWD_TITLE}</a>"}.join("<br>"){{/html}}

More on this issue: this is, for sure, a clear error message for anybody mastering
Groovy...
Caused by: javax.script.ScriptException: startup failed:
Script167.groovy: 4: Ambiguous expression could be either a parameterless closure
expression or an isolated open code block;
solution: Add an explicit closure parameter list, e.g. {it -> ...}, or force it
to be treated as an open block by giving it a label, e.g. L:{...} @ line 4, column 2.
{{html}}
^
Please, how this must be applied to the way Vicent is proposing to nest the XWiki html
macro?
println "{{html}}<your html here>{{/html}}" >>>> The problem is with nested quotes
IMHO.

Done! Thank you very much!
Could it be useful to make some note about this behavior in XWiki Platform > XWiki
Syntaxes page?
http://platform.xwiki.org/xwiki/bin/view/Main/XWikiSyntax#HMacros
Thanks!
Thanks!!!

I'm trying to move it to 2.0. But using the same lines results in that exact text
being displayed in the page, but not the URL showed in 1.0 syntax.
