Extra JSF lifecycle after a4j:support
I have a rather complex JSP that includes an inner JSP with a tabbedPane. The tabbedPane has a tab with a table containing
a link displaying a price which, upon clicking, changes the link to an HtmlInput. The HtmlInput has an a4j:support with an
action that accepts the changed price (recalculating other amounts surrounding the price) and then reRenders the table upon
the 'onChange' event.
Everything works fine - after the event fires the prices/amounts are changed and the table is reRendered with the HtmlInput
reverting back to a link. However, if I then click a button on the parent JSP (to go to the next page, for instance), the
JSP lifecycle steps through each phase but doesn't fire the action tied to the button. Click the button again, and now it
works as expected.
Why the extra lifecycle? Is A4J not finishing something on the a4j:support event that finishes when the button is clicked?
The button on the parent JSP and the included JSP with it's table/links/a4j:support etc., are all under one h:form. Here are
some code snippets:
Rich Column for price on table:
<rich:column>
<f:facet name="header">
<h:outputText value="Price"/>
</f:facet>
<h:commandLink id="linkPropListPrice"
value="#{item.proposedDiscountPrice}"
rendered="#{!SpreadsheetTabBean.renderProposedPriceInput && !SpreadsheetTabBean.spreadsheet.uploaded}"
action="#{SpreadsheetTabBean.showProposedPriceInput}"
immediate="true"/>
<h:inputText id="inPropListPrice"
value="#{item.proposedDiscountPrice}"
rendered="#{SpreadsheetTabBean.renderProposedPriceInput}"
immediate="true"
valueChangeListener="#{SpreadsheetTabBean.listenProposed}" >
<a4j:support immediate="true"
action="#{SpreadsheetTabBean.changeProposedPrice}"
event="onchange"
reRender="proposedTable"/>
</h:inputText>
</rich:column>
Bean methods:
public String changeProposedPrice()
{
this.setRenderProposedPriceInput(false);
spreadsheet.setProposedPriceAt(this.getNewValue(), this.getDiscountLevelChanged());
ssSvc.saveSpreadsheet(spreadsheet);
FacesContext context = FacesContext.getCurrentInstance();
context.renderResponse();
return null;
}
public void listenProposed(ValueChangeEvent e)
{
BigDecimal bd = (BigDecimal)e.getNewValue();
UIComponent component = e.getComponent();
String id = component.getId();
if (id != null && id.equals("inPropListPrice"))
{
if (bd.scale() < 2)
{
bd = bd.setScale(2, RoundingMode.HALF_UP);
}
}
this.setNewValue(bd);
PricingModel pm = (PricingModel)proposedModel.getRowData();
this.setDiscountLevelChanged(pm.getDiscountPercent());
}
And here's an a4j:log - Nothing added to the log when the button was clicked -
