In the WLP 8.1.x version of the netui-data taglib, there were <netui-data:d=
eclareControl> and <netui-data:callControl> tags for making a control metho=
d call from a JSP.  The Beehive 1.0.x netui-data taglib has neither tag; ho=
wever, the documentation seems to hint that it is possible to call a contro=
l using the <netui-data:callMethod> tag.  The API doc actually refers to a =
"controlId" attribute that does not actually seem to be a part of the tag i=
nterface.  See:

http://beehive.apache.org/docs/1.0.2/netui/apidocs/taglib/beehive.apache.or=
g/netui/tags-databinding-1.0/callMethod.html=20
=20
Is it possible to make a call to a custom control (which in turn calls an E=
JB control and the Portal Caching framework) from a JSP in a Beehive pagefl=
ow?  Will the control be executed in a control container so that the EJB co=
ntrol actually works?=20=20
=20
If so, could someone provide some sample code for my use case?  From the JS=
P, I would like to call the getOrganizations() method on a custom control c=
alled com.mycustomer.control.ListCacheControl, returning the java.util.List=
 result in a pageContext variable called "orgs".  The result would then be =
used as the optionsDataSource for a <netui:select> tag.

My incorrect attempts:
<netui-data:callMethod object=3D"${pageFlow.listCacheControl}" resultId=3D"=
orgs" method=3D"getOrganizations"></netui-data:callMethod> // ListCacheCont=
rol exposed as a public pageFlow attribute - I don't like this

<netui-data:callMethod object=3D"com.mycustomer.control.ListCacheControl" r=
esultId=3D"orgs" method=3D"getOrganizations"></netui-data:callMethod>

Thanks,
Scott
