ADF action binding with Generics

ADF binding does not support Generics See below,

https://community.oracle.com/message/4304798

For example, in AM you have List<Long> getListCount() {}, you will get following exception.

Go to binding source, change following

<NamedData NDName="testList" NDType="java.util.List&lt;java.lang.Long>"/>

to

<NamedData NDName="testList" NDType="java.util.List"/>

Exception

ADF Install tag lib

Add following to jsff
xmlns:c="http://java.sun.com/jsp/jstl/core"

But got complaint error:
Tag library referenced Tag library referenced but not installed

Go to
Project --> Select Project Property --> Select JSP Tag libraries 

There you can add library needed.

ADF Table with context menus

We can add ADF Table context menus so user right clicks on a row, the context menu will be displayed.


add a facet to table

<af:table>
        <f:facet name="contextMenu">
           <af:popup id="cmpop" contentDelivery="lazyUncached">
               <af:menu id="cmm1" text="My Context Menu">
                  <af:commandMenuItem text="Do something"
                          id="cmi1"
                          actionListener="#{backingBeanScope.myBean.myActionListener}"/>
               </af:menu>
          </af:popup>
        </f:facet>
</af:table>

 Table has another property:
          contextMenuSelect="true" so this ensures the right click on a row will make the row selected and context menu shows up.

Note:

• add <af:showPopupBehavior triggerType="contextMenu" popupId="cmpop"/> if you like for table columns for context menu display
• add partial triggers so UI refreshes after context menu execution.

Refresh adf region without contextual event

The trick is region will refresh whenever its input parameter changes.

• Go the page with the region which will be refreshed.
• Go to binding tab and select the region from Executables
• add an input parameter id=refreshInd value=#{pageFlowScope.dummyParam}
• set Refresh=ifNeeded

So any point, you want the region to refresh, 

ADFUtils.getPageFlowScope().put("dummyParam", Long.toString(System.currentTimeMillis()));

Another trick is using current mill second as input value - that's guaranteed to have a new value for the input.

Missing IN or OUT parameter error in ADF binding variable

See blog psot below:

The infamous Missing IN or OUT parameter error

In short:

make sure the bind variables are set to required. Bind variables that are marked as optional are only good to be used in View Criterias.
