Hi Scott,
Here's a pattern I've used in the past to instantiate a custom control
from within a JSP. The control will be executed in a Control
Container Context.
To instantiate:
<%
com.mycustomer.control.ListCacheControlBean bean =
Controls.instantiate(com.mycustomer.control.ListCacheControlBean.class,
null,
ControlThreadContext.getContext(), "mybean");
%>
Where 'mybean' is the control id, optionally this parameter may be
null, in which case the control id will be generated by the controls
framework.

In the WLP 8.1.x version of the netui-data taglib, there were <netui-data:declareControl> and
<netui-data:callControl> tags for making a control method call from a JSP. The Beehive 1.0.x
netui-data taglib has neither tag; however, the documentation seems to hint that it is possible to call a
control 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 interface. See:
http://beehive.apache.org/docs/1.0.2/netui/apidocs/taglib/beehive.apache.org/netui/tags-databinding-1.0/callMethod.html
Is it possible to make a call to a custom control (which in turn calls an EJB
control and the Portal Caching framework) from a JSP in a Beehive pageflow?
Will the control be executed in a control container so that the EJB control
actually works?
If so, could someone provide some sample code for my use case? From the JSP, I would like to
call the getOrganizations() method on a custom control called
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="${pageFlow.listCacheControl}" resultId="orgs"
method="getOrganizations"></netui-data:callMethod> // ListCacheControl exposed as a public pageFlow
attribute - I don't like this
<netui-data:callMethod object="com.mycustomer.control.ListCacheControl" resultId="orgs"
method="getOrganizations"></netui-data:callMethod>
Thanks,
Scott
