Check if the VO Row is updated! ADF

• Add a Transient Attribute to the View Object (e.g Row Status(Integer / BigDecimal), make sure this attribute is made Updatable - Always)
• Define the Row Impl for the VO
• Getter method the row-

 
    /**
     * Gets the attribute value for the calculated attribute RowStatus.
     * @return the RowStatus
     */
    public Integer getRowStatus() {
        //return (Integer) getAttributeInternal(ROWSTATUS);
        byte entityState = this.getEntity(0).getEntityState();
        return new Integer(entityState);
    }

   

Integer values:

2 - Modified

0 - New

1 - Unmodified

-1 - Initialized 

// In the backingBean, We can update this row (e.g Last Updated by) only if the RowStatus is 2

// Example
byte entityState= eo.getEntityState();
if(entityState==EntityImpl.STATUS_MODIFIED)

Oracle Fusion Middleware Tag Reference for Oracle ADF Faces Skin Selectors 

Update (web.xml) this context-param to true (make sure you change it back to false...before deploying the app to production environment); this reflects the changes made in 'css' without being to redeploy the ear again

 <context-param>
        <description>If this parameter is true, there will be an automatic check of the modification date of your JSPs,
                     and saved state will be discarded when JSP's change. It will also automatically check if your
                     skinning css files have changed without you having to restart the server. This makes development
                     easier, but adds overhead. For this reason this parameter should be set to false when your
                     application is deployed.</description>
        <param-name>org.apache.myfaces.trinidad.CHECK_FILE_MODIFICATION</param-name>

        <param-value>true</param-value> <!--by default it's false-->

    </context-param>

DynamicVO with Dynamic Table ADF

File Upload/Download example ADF (dont' want pdf to open by default in browser?)

I used File upload/download example by Ashish Awasti  blog posting to demonstrate this.

Filename attribute on File Download listener is the trick. We had to use this popup approach as Workaround for IE back button issue (browser back button exits the taskflow and takes to ParentTF)

Cheers!
