I have a problem with sorting my ExtJS grid. I'm using Ext JS version 5.1.1.451.
The grid loads well but when I try to sort the columns I get the "Uncaught TypeError: Cannot read property 'isSynchronized' of undefined" error.
The method addCls
is triggered on mouse movement and when the error occures, me.getData()
returns undefined
, where me
is
constructor
$observableInitialized: true
component: constructor
config: Object
destroy: () {}
dom: null
el: null
events: Object
hasListeners: statics.prepareClass.HasListeners
id: "ext-quicktips-tip"
initConfig: () {}
initialConfig: Object
isDestroyed: true
lastBox: null
managedListeners: Array[0]
shadow: null
This is the addCls
method where the error occurs:
addCls: function(names, prefix, suffix) {
var me = this,
elementData = me.getData(),
hasNewCls, dom, map, classList, i, ln, name;
if (!names) {
return me;
}
if (!elementData.isSynchronized) {
me.synchronize();
}
Has anyone encounter this problem before? Is it a known issue or am I doing something wrong?
Thank you
I've overriden the handleMouseDown method and commented out the quick tips part.
Ext.override(Ext.dd.DragDropManager, {
handleMouseDown: function (e, oDD) {
var me = this,
xy, el;
me.isMouseDown = true;
//if (Ext.quickTipsActive) {
// Ext.tip.QuickTipManager.ddDisable();
//}
me.currentPoint = e.getPoint();
if (me.dragCurrent) {
me.handleMouseUp(e);
}
me.mousedownEvent = e;
me.currentTarget = e.getTarget();
me.dragCurrent = oDD;
el = oDD.getEl();
Ext.fly(el).setCapture();
xy = e.getXY();
me.startX = xy[0];
me.startY = xy[1];
me.offsetX = me.offsetY = 0;
me.deltaX = me.startX - el.offsetLeft;
me.deltaY = me.startY - el.offsetTop;
me.dragThreshMet = false;
}
});
If anyone has a better answer, post it and I will mark it if it's good.
I was having this issue because I was rendering a different value based on some mappings I needed to load separately. If the mappings weren't loaded into the viewmodel then the renderer seemed to fail with that error.
I solved it with some checks for existence of what it needed:
// on the renderer for the column where I have a combobox editor field
renderer: function(value) {
var mappings = vm.get('ruleMapping')
if(!!mappings) {
var rule = _.find(mappings, ['id', value]
if(!!rule) {
return `<a href="${rule.link}>${rule.name}</a>"`
}
}
return 'Setting value'
}
