    Default Unanswered: Odd placeholder behaviour

    Unanswered: Odd placeholder behaviour


    Hey guys,

    I'm trying to dev an sencha app and have come across a problem which I can't seem to get around.

    I have two selectfields (dropdown menus). The second one is dependant on the first. What I want to do is : have a placeholder if there are several items in the store and have no placeholder (or placeholder = null) if the store only contains one item.

    Here is my listener :

    Code:
    listeners:{
                load : function(myStore){
                   var count = myStore.getCount();
                   if(count != 1){
                       Ext.getCmp('strClassReference')._placeHolder = rcChooseDocType;;
                   }else{
                       Ext.getCmp('strClassReference')._placeHolder = null;
                   }
                }
              }
    My problem is that the rendering doesn't seem to function properly. I always have the placeholder of the previous choice even though the value of the placeholder is correct (checked with a console.debug)

    Does anyone have an idea how to refresh the component ? I've tried the show and hide function, but I haven't had any luck

    Thanks guys

    Default


    You can't just set the property, you need to use the method: http://docs.sencha.com/touch/2-2/#!/...setPlaceHolder

    Thank you for answering but I have also tried with setPlaceHolder() and get the same result.

    It seem that what is rendered is the placeHolder value of the previous choice.
    Any more ideas ?
