Invokes a Template, as either a pagelet or an element, for the purpose of rendering an asset.

tname
refers to a typeless template, prefix the template name with '/'.pagelet
. Setting this attribute value to element
will result in the template being called as an element. This is useful if a nested pagelet is not necessary or desireable (i.e. would be overkill) for the target Template. When the style is element
, the scope of the called element is local: only variables specified as arguments and attributes will be accessible to the called element, and variable values in the caller will not be affected. When the style is set to embedded
, the nested template is invoked as a pagelet without using Satellite Server. This causes the pagelet to be independently rendered (and possibly cached) by Sites but the result of the pagelet is embedded in the caller, just as if it had been called as an element. Satellite Server does not see embedded pagelets as separate from their caller; they are simply part of the output of the caller. Note that if this is set to element or embedded
, then the invoked Template will be embedded in the caller, and this can have performance, dependency, and caching implications, which can be good or bad depending on your code). pagelet

variable)Template
or a CSElement
asset. The default value is Template
. This value must be set to CSElement
if the code is a CSElement asset. See also: tid
. ttype
should be set to CSElement
. The proper value is automatically retrieved by Sites from the ICS scope if it is not explicitly specified: if ttype
is set to CSElement
, tid
is given by the Sites variable eid
. It is given by the Sites variables tid
in all other cases.insite:calltemplate
tag. See insite:calltemplate for more information.This tag causes a specific asset, identified by the tag attributes c
and cid
, to be rendered by a specific template, specified by the tname
tag attribute.
Since several Templates with the same name can coexist (as long as they are applicable to distinct asset types), the following convention applies for tname
:
tname
starts with "/
" then the typeless template corresponding to tname
will be called. For example: <render:calltemplate tname="/Foo" c="Article" .../>
will result in the typeless Template with name "Foo" to be called.tname
and asset type (designated by the tag attribute "c
") will be called. For example: <render:calltemplate tname="Foo" c="Article" .../>
will invoke the Template with name "Foo", applicable to the asset type "Article".From a caching point of view, the template can be rendered either as an inline element or as a nested pagelet (see the style
attribute above).
Instances of this tag must contain information about who the caller is in order to operate correctly. The caller must be either another Template or a CSElement. This tag will not operate correctly without valid information about the caller (see tid
& ttype
above). Note that Sites only requires ttype
to be set in the case of a CSElement (ttype="CSElement"
). The value of tid
and ttype
are implicitly determined by Sites in all other cases.
This tag is the preferred method for invoking a template. Here are some general guidelines in order to render something other than a Template:
render:callelement
is generally used to render a CSElement or standalone ElementCatalog entry rendering markupics:callelement
is generally used to render a CSElement or standalone ElementCatalog entry processing arbitrary logic, but not necessarily rendering markuprender:satellitepage
is used to render a SiteEntry or standalone SiteCatalog entry as a nested pagelet (i.e. equivalent to using render:calltemplate
with style="pagelet"
)render:contentserver
is used to render a SiteEntry or standalone SiteCatalog entry as an embedded pagelet (i.e. equivalent to using render:calltemplate with style="embedded"
)The possible values of errno
include:

The following example calls the Detail
template of the incoming asset, i.e. the asset which type and id are determined by the value of the c
and cid
Sites variables.
<render:calltemplate tname="Detail" args="c,cid" />
This syntax is strictly equivalent to the following:
<render:calltemplate tname="Detail" c='<%=ics.GetVar("c")%>' cid='<%=ics.GetVar("cid")%>' />
Extra template arguments can be passed as follows:
<render:calltemplate tname="Detail" args="c,cid,foo" > <render:argument name="variable1" value="value1" /> <render:argument name="variable2" value="value2" /> </render:calltemplate>which results in:
foo
being passed with the corresponding Sites variable value, i.e. the value returned by: ics.GetVar("foo")
.c
being passed with the corresponding Sites variable value, i.e. the value returned by: ics.GetVar("c")
.cid
being passed with the corresponding Sites variable value, i.e. the value returned by: ics.GetVar("cid")
.variable1
being passed with value value1
variable1
being passed with value value1
Note that this example assumes that foo, variable1, variable2 are defined as cache criteria for the corresponding Detail template.
