Updating bean properties on submission of a button from different form

[lenyas66]

Could somebody explain to me the behavior I have noticed in processing of XHTML page, which consists of two separate h:forms?

I have a command button on one form, which is used to add rows to the table and update the values on the server.

<a4j:commandButton id="addPortButtonInp" value="Add"

action="#{qtBeanParam.addProduct}" immediate="false" reRender="selectedProducts,sectorSel,periodicity,grossnet,retTypeLbl,retTypeSel"

styleClass="command-button">

</a4j:commandButton>

It also supposed to refresh some components located on other form. I noticed that when these components are refreshed,

they change the values to the ones from the bean9server), even if I changed them before clicking on the button.

If I click another button located on the form that contains components, the values that were changed on the screen are saved to the server properly.

<a4j:commandButton id="runButton" value="Run Report"

action="#{qtBeanParam.processCommonInput}" immediate="false"

styleClass="command-button"

oncomplete="doPopup('qtBeanParam', #{qtBeanParam.curIndex})">

</a4j:commandButton>

action="#{qtBeanParam.processCommonInput}" immediate="false"

styleClass="command-button"

oncomplete="doPopup('qtBeanParam', #{qtBeanParam.curIndex})">

</a4j:commandButton>

Would appreciate advice how I could work around this issue.

Please see XHTML page attached.

Thanks,

Leonid

Hi Leonid,

Only inputs that reside in the current form are submitted to the server, thus you are loosing values. s a workaround you can submit arbitrary form (still only one) by placing a4j:jsFunction in it.

I see. Makes sense.

Hi Nick,

I noticed another problem: when I try to re-render objects located on 2 forms only objects located on one form are re-rendered.

Please see attached XHTML file. This button points to components located on 2 forms.

<

a4j:commandButton id="loadTemplate" value="Load"

action="#{qtBeanParam.loadTemplate}" immediate="true"

reRender="selectedProducts,grossnet,sectorSel,periodicity,periodType,timePanel,selectStatistics,sortingPanel"

styleClass="blue-button">

</a4j:commandButton>

Only first component ("selectedProducts") is re-rendered. I verified that all bean values are changed correctly on the server.

Is there a way around it?

Thanks,

Leonid

do you using region's? renderRegionOnly=true could cause this.

sorry.. looked for attached sources and seems things looks fine... What do you see in a4j:log related to re-rendering? Because in similar case but for poll reRendering between forms - works http://livedemo.exadel.com/richfaces-demo/richfaces/poll.jsf

Ilya,

It doesn't seem that the issue was with 2 different forms, but still I was unable to figure out what was causing it.

Since I needed pretty much whole page, which consists of two forms, to be re-rendered, I used workaround and did it from the bean as follows (see function below).

Not sure, if it is the best solution, but it worked for me. I attached XHTML file as well.

private

String cleanReRender() {

final ExternalContext ectx = FacesContext.getCurrentInstance().getExternalContext();

// final HttpSession session = (HttpSession)ectx.getSession(false);

// session.invalidate();

String sPageLink;

if ( reportType == "P")

{

sPageLink =

"/piQTPerformanceReturns.faces";

}

else

{

sPageLink =

"/piQueryTool.faces";

}

final HttpServletResponse response = (HttpServletResponse)ectx.getResponse();

try {

response.sendRedirect(sPageLink);

}

catch (IOException e) {

logger.error("Problem redirect to original page. Please contact IT support.");

}

return sPageLink;

}
