Dynamic datasource query in Content Presenter

Question

I have a Documents region with a custom Content Presenter template.
I would like to use a dynamic datasource query with this, which makes use of the currently logged in user and the user's role.
The task flow parameters look like this now:
<parameters>
<parameter id="taskFlowInstId"
value="${'afd37bc3-bd2e-4e97-b838-74c975529633'}"/>
<parameter id="datasourceType" value="${'dsTypeQueryExpression'}"/>
<parameter id="datasource"
value="${'SELECT * FROM ora:t:IDC:GlobalProfile WHERE ora:p:dDocType = \'Dagbericht\''}"/>
<parameter id="templateCategory" value="${''}"/>
<parameter id="templateView" value="${'dagberichten.list.template'}"/>
<parameter id="maxResults" value="${'3'}"/>
</parameters>
What are my options to achieve this?

Jaap,
You can use expression language in that query to make it dynamic.
You could either build the full query from a managed bean or just some parameters.
here's how you can do it when building the query from a MB:
This should be the method in your bean:
public String getQuery(){
  String user = ADFContext.getCurrent().getSecurityContext().getUserName();
  String query = "SELECT * FROM ora:t:IDC:GlobalProfile WHERE ora:p:dDocType = 'Dagbericht' and ora:p:dCreatedBy = '" + user + "'";
  return query;
}Your datasource parameter should be something like this:
<parameter id="datasource" value="#{yourBean.query}"/>note: the "and ora:p:dCreatedBy..." might not be correct but it shows how you can dynamicly build the query.
Hope this helps.
