ValueChangeListener is not invoked

[Amit Jain]

Hi,

I have an inputText and I have provided a method binding for 
ValueChangeListener to it. When I change its value to some text and 
submits the page my listener method is invoked and working fine. But 
when I change its value to empty("") the value change listener is not 
invoked. I am not sure that if it a feature or a bug in myfaces. Is 
there any workaround to handle such situation?


Thanks
Amit

Re: Sub columns in datatable

[Amit Jain]

You can do it by using datatable inside a datatable. So basically inside 
second column there will be datatable and you have to change value to 
the datatable accordingly.

HtmlPanelgrid to support value

[Amit Jain]

HI 
 
I am creating a custom component which in short is 
something like panelgrid with value. I extended my Component class with 
HtmlPanelGrid and implement it with EditableValueHolder. Now the problem I 
am facing is setter and getter method of my component class are never invoked. 
So my new value is not saved and my older value is displayed on screen. Can 
someone suggest me what else do I need to make my panelgrid support value.

Re: How to make complex layout using datatable?

[Amit Jain]

As far as i know dataTable dont support colspan and 
rowspan. If you need such thing, you have to make your own renderer for 
dataTable(extend HtmlTableRenderer) to support colspan and rowspan.

Components disappearing!

[Amit Jain]

HI !

I am trying to make a custom component, a sortable column which is a column
with an output text and 2 command buttons at its header.

I extends the UIcolumn component and put a htmlPanelGrid in it header.
HtmlPanelGrid contains an output text and 2 command buttons.

I am trying to a assign id to these component using View as

FacesContext.getCurrentInstance().getViewRoot().createUniqueId();

Now it displays everything fine for the first time. But when I click any of
these buttons, cells of the column disappears and I left with empty column.

Does any one have any idea why this is happening.

With regards
Amit
ps: When I don't assign ids everything works fine except that I got a
warning saying automatic id is assigned to these components.
