Please ensure the existing component has been destroyed (`Ext.Component#destroy()`. I can go back to the previous screen but the cannot go forward again without getting the above error.

问题 While test automating a web application, I get dynamically generated ext-gen IDs. I tried using xpath but the test cases are failing. I went through different websites but did not find any luck. Can somebody help me? Thank you, Srinivas Marthi 回答1: For automated testing, the auto-generated ID-s of ExtJS are best avoided altogether.

问题 We have a requirement in which we need to hide the header of the window and for this we are using header:false But if we use header:false, then window can not be dragged at all.

问题 I've a dataview, written with extjs 7.1 modern tookit, with a template with an anchor tag and a select event: https://fiddle.sencha.com/#view/editor&fiddle/34bd Ext.create({ renderTo: document.body, xtype: 'list', itemTpl: '<div class="contact"><a onclick="event.preventDefault();console.log(\'link\');" href="{firstName}">{firstName}</a> <b>{lastName}</b></div>', store: { data: [{ firstName: 'Peter', lastName: 'Venkman' }, { firstName: 'Raymond', lastName: 'Stantz' }, { firstName: 'Egon',

问题 Actually I'm going to implement a tree view, where the user should have the option to reorder the structure with drag and drop. Actually I can't figure out how to enable drag and drop. I found a lot of examples using the 'treeviewdragdrop' plugin, which is just working with the classic toolkit.

问题 I want to display a message from my server in the UI after synchronizing an ExtJS grid. Here's an excerpt of how that goes: this.store.sync({ callback: function (records, operation, success) { // messageProperty accessing code }, success: function (batch, options) { // messageProperty accessing code }, failure: function (batch, options) { } }); Here's a piece of the store definition: proxy: { headers: { 'Accept': 'application/json' }, limitParam: undefined, pageParam: undefined, startParam:
