How to in Jdeveloper ADF – increase the inputcomboboxlistofvalues dialog width


To increase the width of the af:inputcomboboxlistofvalues dialog box.


Recently I have been challenged to increase the width of the af:inputcomboboxlistofvalues dialog box. using contentStyle or inlinestyle will increase the width of the component and the dialog box will remain the same. So i thought of playing with the CSS file and could possibly achieve the width with the following hack.

<af:resource type=”css”>
   min-width: 500px;

How to in Jdeveloper ADF–Single row table selection


How to enable single row table selection?


This seems an obvious question but newbie’s miss to understand this and will find difficulties in fixing this.

So what exactly we do to make the selection happen and confirm that it points to the current row of the af:table.

first, make sure that you have the following entries added to the af:table component of your page


Note: Customers is the tree binding for the table in the page definition file.

So what these entries do?

selectedRowKeys – the state of the selection is stored in this property. This property identifies the current selected row in the collectionModel of the table.

selectionListener – this is a listener that corresponds to the selection of the row. we bind it to the makeCurrent method of the table bindings collectionModel

rowSelection – we make it single row selection.

binder.putLocal("dDocName", "UCM_CLUSTER1001204");
binder.putLocal("RevisionSelectionMethod", "Latest");

try {
ServiceResponse response = idcClient.sendRequest (user, binder);

// get the response as a string
