Java script is not working while coming back to the page.

Question

Hi Experts,
I am working in jdev 11.1.1.3.0 with ADF BC.
I am callling javascript in my jsff, while this javascrip is invoking file download method. this java script i am inovking from another button action, because in some case i need to invoke popup and some case i need to invoke file download for this i have taken one button in that button i am invoking these 2 based on some condition. everything is working fine except if i move another jsff and come back to this jsff then the file download is not happening.
can any one tell me what is the issue here.
java script:
function customHandler(event) {
var exportCmd = AdfPage.PAGE.findComponentByAbsoluteId("pt1:pt_region0:1:cb1")
var actionEvent = new AdfActionEvent(exportCmd);
actionEvent.noResponseExpected();
actionEvent.queue();
java bean:
if(downloadFile!=null){
System.out.println("invoking downloads...............................");
erks.addScript(context, "customHandler();");
} if (requestClause != null){
System.out.println("invoke popup");
executeSactionCheckVO(requestClause);
ADFUtils.invokePopup(this.getP2().getClientId(FacesContext.getCurrentInstance()));
Here my bean is in backing bean scope.
can any one help what may be the issue here. or if you can tell me how to call file download method from backing that can be great help full to me.

Answer 1

Hi:
So it's the "erks.addScript(context, "customHandler();");" may not work properly the next time coming back from another jsff.
And very likely the statement of: var exportCmd = AdfPage.PAGE.findComponentByAbsoluteId("pt1:pt_region0:1:cb1") in your javascript command gave you error. Are you sure that "pt1:pt_resion0:1:cb1" is valid all the time no matter how the page is rendered?
Please mark my answer as 'Helpful' if it helps.
Thanks,
