I am using this.$router.push('/route/path') to change routes in nuxt.
However, when I get to the new route, the page gives an error:
Nuxt Cannot read property propertyname of undefined
However, the property it is referring to is on the previous page on a component which is not loaded in the current page !
I am using nuxt in SPA mode.
when I use location.replace('/route/path'), I dont get the issue, but obviously we dont want that because then a new page is refreshed.

I am getting this error when trying to open Elementor with my custom theme meaning that Elementor page builder won't open. Has anyone come across this before?

This is a jquery issue. I had the same error, it was because jquery was loaded twice, two versions. The one that was puzzling me was getting loaded by GTM, so I couldn't find it in the code.
Michael is right I had the same issue. But the jQuery was hidden in a .js file within the theme.
So just double check jQuery isn't being loaded twice within your themes .js files.
When I found the second copy and removed it, I was receiving an error regarding the "$ is not a function".
jQuery(function($) {
/* Rest of code in file goes here
});
If you are getting the element from a jquery function, you need to extract the raw DOM element first
var e = $("#item1");
var d = e[0];
d.dispatchEvent(new Event('change',{ 'bubbles': true }));
I use project hybridWebView standart. Xamarin.Forms - HybridWebView Custom Renderer
If i use the html file that is in the Android project - Content / index.html - Everything works.
If I use html file which is hosted by mysite.com - The first time the hybridWebViewPage.axml page is loaded, I get the data in a variable var data. If I go to another page, and then go back to the hybridWebViewPage.axml page, I do not get data in the variable var data.
hybridWebView.RegisterAction(data => DisplayAlert("Alert", "Hello " + data, "OK"));
Why is this happening?
Because the hybridWebView.RegisterAction method is called in the construction method of the contentpage which will be called when you navigate to it first time. In addition, when you come back from another page, the construction method will not be called because the instance of it is still in the storge. There is the link about the navigation stack.link
I seem to be struggling with this. I am working on a project management app in Google App Maker. I am using SQL data models. The portion of the app I am having trouble with is several project detail pages linked with a project list page. I have no trouble going from the project list page to the first project detail page.
I have a table widget in the project list page, and the onClick code for a table row is:
app.datasources.Projects.selectKey(widget.datasource.item._key);
app.showPage(app.pages.ProjectPage);
This filters the first detail page with the primary key of the record in focus. No problem here. When I want to navigate the next detail page that has a different datasource (but I still need to filter using the same primary key) I am struggling.
If someone can guide me in making a button in the first detail page that when clicked gets the _key of the project loaded in that current page and filters another detail page for the same project in focus, (using another data model, let's call it ProjectBudgetPage for example) I would really appreciate the help.
This was one my latest attempts at navigation to other detail pages within a project, this was for an onClick event:
var widgets = widget.parent.descendants;
var projectID = widgets.HiddenProjectID.text;
var projectDataSource = app.datasources.ProjectBudgetView.item;
projectDataSource = projectID;
app.showPage(app.pages.ProjectInfoPage);
which results in: (TypeError) : Cannot read property '__gwt_instance' of undefined

I am not sure if I understood properly but I suggest that you start by checking this official App Maker template available here https://developers.google.com/appmaker/templates/partner-management/ which provides a ready-to-run app you can use to manage an internal list of partners, but you can also customize it with your own needs. I recently used most of the UI and logic of this template and I was able to integrate it with SQL data models and it works really great.
I noticed that for this template they are saving the (widget.datasource.item._key) to a Page custom property which you can access afterwards. Custom properties are page-level properties that store data for a single user session. Custom properties are useful when you need to bind properties of multiple widgets to a single value. More info available here https://developers.google.com/appmaker/ui/binding#custom_properties
In your scenario, you can create a new custom property (string) inside your ProjectInfoPage and then you can add a script to the button onClick event in your ProjectPage to save the _key or any other item to a page property. For example:
app.pages.ProjectInfoPage.properties.ProjectKey = widget.datasource.item._key;
app.showDialog(app.pages.ProjectInfoPage);
Then you can get the “ProjectKey” property by adding this to the onAttach event in your ProjectInfoPage:
var key = app.pages.ProjectInfoPage.properties.ProjectKey;
…
In the onAttach event you can filter the new model or pass the property values to a server script. I believe there are other approaches but I hope this helps!
I am new to Flex and trying to modify some existing code. I am trying to It uses and AdvancedDataGrid. In the click event, the ListEvent is passed in, and the code is able to access properties such as event.itemRenderer.data.feature.
I would like to check whether the user has clicked on a parent (group) record or the child record; at runtime, I can see that the property I want to access is event.itemRenderer.listData.hasChildren. However, the listData property of itemRenderer does not show up in intellisense, and when I try to access that at design time, the project will not build because of the error "Access of possibly undefined property listData". But the property .data.feature doesn't show up in intellisense at design time either, and that builds and runs just fine.
What do I need to do to access event.itemRenderer.listData without throwing errors when I build the project? Do I need to capture a different event, or cast the event object or one of its properties into another object that will have the properties I need at runtime (I've investigated these options but cannot find info on how to do that).
Many thanks for any insight.
You probably have to perform a cast using IDropInListItemRenderer and AdvancedDataGridListData. Something like this:
((event.itemRenderer as IDropInListItemRenderer).listData as AdvancedDataGridListData).hasChildren
I'm programming in Flex Builder Burrito for an mobile application.
I'm trying to get a variable from navigator.PopView()
and i found the following site: adobe View and ViewNavigator
On that page is written that you can get to an returnedObject:
The ViewNavigator will save this object internally, and the new view can access it from with the navigator.returnedObject property.
The problem is when I want to acces the returnedObject flash builder doesn't seem to find that even the package isn't found.
I've found my problem on an other site.
There it's plain simple explained.
Do the override public function createReturnObject():Object.
On the page where it needs to be send back.
Then on the popped view, you can acces it by returnedObject.
On same page next lines are
The property is a ViewReturnObject
which contains the object that was
returned
and the context in which the removed view was pushed (See Setting
the View Context).
ViewNavigator.poppedViewReturnedObject
is guaranteed to be set by the time
the new view
receives the add event and will be destroyed after the view receives its
viewActivate
event.
and also a NOTE
Note, the return object is only stored when a view is popped of
the navigation stack
or replaced through the use of the pop and replace navigation
operations (e.g.,
replaceView, popView, etc...). It will be cleared after the new view
receives its
ViewNavigatorEvent.VIEW_ACTIVATE event.
I think should try function to get popuped view poppedViewReturnedObject of ViewNavigator
Its description is also on same page
public function get poppedViewReturnedObject():ViewReturnObject
Hopes that help
