Error in autoSuggestBehavior with using train.

Perevertkin M A

I have:

1. Train in Bounded task flow.
2. 2 ore more jsff pages.

In first jsff page i have af:inputText with af:autoSuggestBehavior ( minChars="2", suggestedItems=<value added in pageFlowScope bean>

When i open train, af:inputText with af:autoSuggestBehavior worked correctly, but when i go to second page and returned to page with af:inputText then af:autoSuggestBehavior don't displayed suggested values. In pageFlowScope bean all values returns, but on client displayed load ring. Weblogic has no error, but the browser has the following error:

suggest-92s23k.js:7 Uncaught TypeError: e._cacheSuggestedItems is not a function

Please, help

How do you go back?

The error is a javascript error pointing to a wrong initialisation. Does your stop have any init method?

I'm use

<af:train var="trainNode" value="#{controllerContext.currentViewPort.taskFlowContext.trainModel}" id="pt_t1">
    <f:facet name="nodeStamp">
         <af:commandNavigationItem text="#{trainNode.textAndAccessKey}" id="cni1"
                                  visited="#{trainNode.visited}"
                                  action="#{trainNode.action}"
                                  selected="#{pageFlowScope.popupMasterBean.currentTab}"/>
    </f:facet>
</af:train>

I have custom init method for train. This method used for start train from selected step. In this case initStep = null

private void initTrain(Integer initialStep) {
    ControllerContext controllerContext = ControllerContext.getInstance();
    ViewPortContext currentViewPortCtx = controllerContext.getCurrentViewPort();
    TaskFlowContext taskFlowCtx = currentViewPortCtx.getTaskFlowContext();
    TaskFlowTrainModel taskFlowTrainModel = taskFlowCtx.getTaskFlowTrainModel();

    oracle.adfinternal.controller.train.TrainModel trainModel =
        (oracle.adfinternal.controller.train.TrainModel) taskFlowTrainModel;

    if (initialStep == null || initialStep < 0) {
        logger.info("Information: No stop set -> Nothing to do");
        return;
    }

    Map<ActivityId, oracle.adfinternal.controller.train.TrainStopModel> mapTrainStops = trainModel.getTrainStops();
    Set<ActivityId> keySet = mapTrainStops.keySet();
    Object[] array = keySet.toArray();
    if (initialStep > array.length) {
        logger.info("Information: no stop with number " + initialStep);
        return;
    }

    TaskFlowTrainStopModel currentStop = mapTrainStops.get(array[initialStep - 1]);
    logger.info("Information:" + currentStop);

    TaskFlowTrainStopModel prevStop = taskFlowTrainModel.getPreviousStop(currentStop);
    while (prevStop != null) {
        oracle.adfinternal.controller.train.TrainStopModel ts =
            (oracle.adfinternal.controller.train.TrainStopModel) prevStop;
        ts.setVisited(true);
        prevStop = taskFlowTrainModel.getPreviousStop(prevStop);
    }
}

And when i remove custom init, error reproduced.

Well, the code looks OK. Can you provide a reproducible est case build on the HR DB schema?
