How to in Jdeveloper ADF – increase the inputcomboboxlistofvalues dialog width


Problem:

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

Solution:

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”>
.adf_dialog_main{
   min-width: 500px;
}
</af:resource>

How To in Jdeveloper ADF – To have hour and Time format restriction for inputText


Scenario:

How to have a Time format restriction for the adf inputText component?

Solution:

To have the time format restriction to restrict the time for upto 23:59 we will have a regex pattern for the af:inputText

<af:inputText label="" id="time" simple="true" value="" contentStyle="width:30px;" maximumLength="5">
<af:validateRegExp pattern"([01][0-9]|2[0-3]):[0-5][0-9]" messageDetailNoMatch="Time Format must match HH:MM" hint="Time Format: HH:MM"/>
</af:inputText>

How to in Jdeveloper ADF–Single row table selection


Scenario:

How to enable single row table selection?

Solution:

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

selectedRowKeys="{bindings.Customers.collectionModel.selectedRow}"
selectionListener="#{bindings.Customers.collectionModel.makeCurrent}"
rowSelection="single"

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.

How To in Jdeveloper ADF Tutorials – Add Date based on another Date


Scenario:

How to calculate the datefield by considering another datefield that’s entered in by the user.
If you have entered a datefield “Today” as 12/04/2012
Now the requirement is to calculate another datefield’s date as 12/04/2012 + 30 days?

Solution:

  • Have two fields in the page. inputDate1 and inputDate2 bounded to the value in the bean as date1 and date2.
  • set inputDate1 autosubmit=true, and inputDate2 partialTrigger is set to the id of the inputDate1

<af:inputDate label="Date 1" id="id1" value="#{bean.date1}" autoSubmit="true"/>
<af:inputDate label="Date 2" id="id2" value="#{bean.date2}" partialTriggers="id1"/>

in the bean for the date fields. have getter and setter

in the getter of the date2 field have the following code


private Date date1;
private Date date2;

public void setDate1(Date date1) {
this.date1 = date1;
}

public Date getDate1() {
return date1;
}

public void setDate2(Date date2) {
this.date2 = date2;
}

public Date getDate2() {
if(date1 != null){
Calendar cal =Calendar.getInstance();
cal.setTime(date1);
cal.add(Calendar.DATE, 30);
date2 = cal.getTime();
}
return date2;
}
