Tips on using af:media to display OrdImage

When you use af:media to display OrdImage type though ADF binding, you are expected to help the binding layer by mentioning the special treatment requirement for the source attribute. Failing to do may result in the following error ;)

javax.el.PropertyNotFoundException: The class 'oracle.ord.im.OrdImageDomain' does not have the property 'media'

Solution is simple, open the page definition and key in CustomInputHandler="OrdDomainValueHandler" for the attribute which is bound to OrdDomain type. The OrdDomainValueHandler class serves as the custom handler for intermedia objects. Note that af:media will use the OrdDomainValueHandler to extract values for specific attributes( source, innerHeight, innerWidth etc. ) which can't be read directly from the associated ViewObject.

Example:

 JSF tag:   
  <af:media source="#{bindings.Image.inputValue.source}"   
      contentType="#{bindings.Image.inputValue.media.mimeType}" id="ot1"/>  
 Page definition entry:  
 <attributeValues IterBinding="ImageView1Iterator"   
      id="Image" CustomInputHandler="OrdDomainValueHandler">  
  <AttrNames>  
      <Item Value="Image"/>  
  </AttrNames>  
 </attributeValues>

How to set Bind Variable Values at runtime ?

In this post I'm sharing a couple of approaches for programmatically setting bind variables values at run time. This post is an attempt to explain 'When to use what ?'[ In case if you are familiar with 'Bind Variables' in ADF BC, please refer Section 5.10, Working with Bind Variables in Fusion Developer's Guide ]

1. Set the Bind Variable value using RowSet::setNamedWhereClauseParam(...)

You can use use the setNamedWhereClauseParam(...) method on the ViewObject interface (which extends oracle.jbo.RowSet) to set the value for bind variables. Please note this sets the value on default RowSet. In other words, this doesn't have any effect on the secondary RowSets that you/system generates.
ViewObject vo = am.findViewObject("EmployeesView1"); vo.setNamedWhereClauseParam("bindVarDeptId", new Number(10)); vo.executeQuery();
2. Set the Bind Variable value using ViewObject's VariableValueManager::setVariableValue(...)
