Hello there
Next step in my xWiki experience: macros …
I tried to create a macro that uses the tree macro inside … rather strange behavior with the empty lines required … however, this is not the question …
The macro has one parameter that I defined as type “java.lang.Integer”.
First challenge:
The parameter is not available after calling
{{tree links=“true”}}
So I had to write
{{velocity}}
#set( $paramLevels = $xcontext.macro.params.levels )
{{/velocity}}
to get it to the global variable scope before using the tree macro … took me some time to figure that out …
Now, using an IF clause did not work with “>”… strange … until I determined that the variable read from the parameter $xcontext.macro.params.levels was of type string.
At the end of the day,
#set( $paramLevels = $xcontext.macro.params.levels )
#set( $levels = 0)
$levels.parseInt( $paramLevels )
did the trick … lot of time spent and a lot learned about Velocity and xWiki
Back to the question: wouldn’t it be great if the parameter type would be inherited by the variable exposed to Velocity?
Thanks
