I have <a4j:outputPanel /> & <a4j:region /> in my code and it works fine
first time i.e. if user has not entered anything into the textfield then
onblur event functions as desirable i.e. clears off other fields on the form
with the help of backing bean method . The problem is when i go back to the
textfield and key in the value it still holds the null value
Here is the snippet
<h:inputText id="propertyTag" value="#{updateDeviceBean.tagNumber}"
disabled="#{!updateDeviceBean.disableMode}">
<a4j:support
action="#{updateDeviceBean.loadAssetDetails}"
event="onblur" reRender="mypanel" />
</h:inputText>
<a4j:outputPanel id="mypanel">
....
</a4j:outputPanel >
Backing Bean method
public String loadAssetDetails() {
if (!StringUtils.isEmpty(tagNumber) && !StringUtils.isEmpty(selectedAsset)){
System.out.println("In not null");
}
else if(StringUtils.isEmpty(tagNumber)){
System.out.println("In tagNo null");
disableMode = false;
return null;
}
else{
System.out.println("In else");
disableMode = false;
return null;
}
}
