    Default [CLOSED] ComboBox list element style with height: 0

    [CLOSED] ComboBox list element style with height: 0


    Hi Guys,

    we have a little problem with our combobox which does not displays any list items. We have found out that the height of the x-combo-list is just 0...The ComboBox it self is on a Ext.Panel which is at the startup not visible/collapsed.

    <div class="x-layer x-combo-list " id="ext-gen297" style="position: absolute; z-index: 11000; visibility: visible; left: 132px; top: 577px; width: 183px; height: 0px; font-size: 12px;"><div class="x-combo-list-inner" id="ext-gen298" style="width: 183px;"><div class="search-item x-combo-selected"></div><div class="search-item"></div><div class="search-item"></div><div

    Any idea what problem it could be? We using extjs with geoext and other js libs.

    Did you configure the combobox with lazyInit:true (which is the default)?

    Hi,
    no - but it does not solved our problem after I add it. Tested with Opera and Firefox(newest Version)


    Our combobox:

    test.Box = new Ext.form.ComboBox({
    columnWidth: 0.50,
    store: store,
    valueField: 'id',
    displayField: 'text',
    lazyRender: true,
    mode: 'local',
    value: 0,
    lazyInit:true ,
    typeAhead: true,
    triggerAction: 'all',
    editable: false
    });

    Hi,

    EDIT: Ok you can close it. We did have found our problem. We have overwritten the JS self object.

    ok the failure happen here - i got for hb NaN.

    Ext.lib.Dom.getViewHeight(): undefined
    Even Ext.lib.Dom.getDocumentHeight() is NaN

    restrictHeight : function(){

    this.getSize().height: 22
    ha: 91
    Ext.lib.Dom.getViewHeight(): undefined

    hb = Ext.lib.Dom.getViewHeight()-ha-this.getSize().height,


    ha: 91
    hb: NaN
    minHeight: 90
    pad: 2

    space = Math.max(ha, hb, this.minHeight || 0)-this.list.shadowOffset-pad-5;

    maxHeight: 300
    space: NaN
    h: 80



    ...

    h = Math.min(h, space, this.maxHeight);

    ...
    }
