dataTable: value-action called 3 times

["Nahrwold, Helge" <He...@LP-GMBH.com>]

Hi all,

i've a little question again! :)

There is a dataTable in my mask:

<t:dataTable id="auftragTable" 
	border="0"
	bgcolor="#C0DAEA"
	styleClass="table"
	style="width: 100%;"
	cellspacing="1"
	headerClass="table_header"
	rowClasses="table_row_1, table_row_2"
	rowOnMouseOver="highlightTableRow(this);"
	rowOnMouseOut="unHighlightTableRow(this);"
	var="auftragKopf" 
	value="#{dispoAuftraege.auftragKoepfe}" 
	varDetailToggler="detailToggler">

Now I've seen in debug that the function #{dispoAuftraege.auftragKoepfe} in
value is called 3 times on load.
Why this?

Greets,
Helge

The JSF specification doesn't guarantee that the getters will be called only
once (different phases call same getter method..). So you should not put
high cost codes into the getter methods. Also you can look at here
