<h:selectOneMenu id="readyToIssue"
value="#{suba na.requiredInd}">
<f:selectItem itemValue="Y" itemLabel="Yes" />
<f:selectItem itemValue="N" itemLabel="No" />

There are three status of a field in database. If the database table has "P" state yes and no should be disabled and if "the status is "yes or no" "P" should be disabled.

You can write a method in the backing bean as below

public boolean isItemProcessed()
{
if("Processed".equals(data))
return true;
else
return false;
}

Then in the page,

<f:selectItem itemValue="Y" itemLabel="Yes" itemDisabled="#{!bean.isItemProcessed}"/>
<f:selectItem itemValue="N" itemLabel="No" itemDisabled="#{!bean.isItemProcessed}"/>
<f:selectItem itemValue="P" itemLabel="Processed" itemDisabled="#{bean.isItemProcessed}"/>

If you do not want to write a separate method, you can directly compare the data with itemDisabled="#{bean.data == "P"}" and itemDisabled="#{bean.data != "P"}

Somebody asked this question about 2-3 months ago. Search this forum and you'll find a detailed discussion about it.

Also, you can make your code and XML more readable if you use the "Code" button on our message editor.
