Are inline macros cached somewhere?
Hello!
I have the following problem:
I have two pages userRequests.vm and vendorRequests.vm.
The first one has userRequests.vm:
#macro( requestItemActions $requestId )
<user specific actions>
#end
#parse("includes/requestView.vm")
-----------------
And the second one vendorRequests.vm:
#macro( requestItemActions $requestId )
<vendor specific actions>
#end
#parse("includes/requestView.vm")
------------------
The file that is included (includes/requestView.vm) contains an
interation over some items and calls the macro requestItemActions for
each item.
The problem is that the inline defined macro is somewhat cached
because after the first parse of the temlate it is remambered and in
both pages (vendorRequest.vm and userRequest.vm) is used the same
template.
Do you have any idea why it is not working?
I tried with the
velocimacro.permissions.allowInlineToOverride=true
but it still isn't working.
Thanks in advance.

Limiting yourself to just one velocimacro for both situations isn't a
bad idea. :)
You might also try these settings:
velocimacro.permissions.allow.inline = true
velocimacro.permissions.allow.inline.to.replace.global = false
velocimacro.permissions.allow.inline.local.scope = true
I believe that will keep your #requestItemActions macro local to their
defining templates, but i think (not 100% sure at the moment) the
mechanics of #parse means the macro will also be available to
templates parsed by the template that defines #requestItemActions. If
not, then try this:
velocimacro.permissions.allow.inline = true
velocimacro.permissions.allow.inline.to.replace.global = true
velocimacro.permissions.allow.inline.local.scope = false
This is inefficient and not really recommended, since it keeps
replacing the global #requestItemActions every time, but i think it
should also work.

Hello,
I think that in velocity all macros have a global scope.
So whenever you define a macro it will by put in this global area. And I
would expect that velocity doesn't parse an "already known" macro twice
for performance reasons.
What can you do?
Define one macro with a second parameter to determine the scope
(user/vendor).
Before the parse you set a global variable which helds the actual scope.
In your RequestView you call the macro with this global variable.
Define a macro like:
#macro( requestAction $id $scope )
#if ("user".equals($scope)
<user actions>
#else
<vendor actions>
#end
#end
In your user view:
#set ($GlobalActualScope = "user")
#parse("includes/requestView.vm")
In your requestView call the macro like:
requestAction $actualId $GlobalActualScope
Waiting for an expert what he says. ;-)
