[F/OS] - Dynamic Components Extension (for every component) 2.3.0

@David

is it possible that the extension first checks if the component has been created and set only when done?

So you basically want SetProperty block to wait the app until extension is created?

It was just my thought. im not sure how things will work on async method. im fine with any method you bring for us

@David

im not sure how things will work on async method

This table may help you a bit

	Asynchronous	Synchronous (current)
Execution Speed	Same	Same
Execution Time	Same	Same
Execution Method	Doesn’t hang the main thread, other blocks will be executed before previous has task completed.	Hangs the main thread, other blocks will be executed after previous task has completed.
What happens when executing Create block	It is unknown if the component is created or not because Create block won’t wait until the component is created.	It is known that component is created because Create block will wait until the component is created.
What happens when executing SetProperty block	It may give an error if the component is still not created yet.	It never gives an error because Create block will hang app until the component has created.
How to learn if the component is created without an event?	Use a Clock to check if the component is created continuously. Otherwise, you can’t know without using an event.	When the next block executes.
How to learn if the component is created with an event?	Use the related event.	When the next block executes, or use the related event.

Doesn’t hang the main thread,
other blocks will be executed before previous has task completed.

this is why i need async

Let’s suppose I made this extension work asynchronous and added a when ComponentCreated event, so; [image] Also, I don’t see any reason to make this extension asynchronously, because components are already created in milliseconds. (Well, a lot of components, means a lot of time) It doesn’t take a lot of time unlike how Web component takes time while sending and receiving data.

Another example with TaifunFile extension

That will need lots of logic if you creating components in an arrangement - Because you have to wait until the component is finally created.

@yusufcihan

I’m thinking of publishing the new versions with two releases, as asynchronous and as synchronous. So people can use any release that they want. And both can be updated together, maybe?

So what’s your decision?

So what’s your decision?

I will wait for more feedbacks, let me see what others will think about it.

[David (‎ David Ningthoujam)]

that’s so kind. i hope some people will involve.

This a good idea, If users will know the difference between them, then it will be helpful.
And also think about my request about the
Component Created Event.

Hey guys, I’ve been using this extension for my app to build out my forms dynamically based on lists so that I can easily update what needs to be in there and push out updates. This has worked great for previous forms, like the daily truck check lists for our field technicians (this app is for a small lawn company). I am trying to build another one and everything seems to work fine in the companion until I build the app. Then I get a series of errors referring to trying to get an item of index 0 from a list.

I get four of these each showing the list with a different number of items, I am trying to build four sections of radio buttons out

I have tried to locate what is causing this and am coming up empty-handed. My employer is looking to impliment this ASAP and I’m hoping I can get someone to help me track this down? I think it’s related to this extension, which is why I’m posting this here. When I disabel the procedure that uses this extension to build out the sections the error stops (but the form doesn’t build dynamically).

I have the sections listed out in a Dictionary like this.

Then I grab the keys and put them in a list that I use to create each section in initialize

Then I create the section.

Each individual component has a procedure as well, like this

and this

And I have a procedure to build out each question with the radio buttons needed.

I know this is long, I’m just really stumped. Any help would be appreciated.

Not this extension’s fault… Apparently trying to update the Checked property of a toggle switch with the block is what is messing it all up. Who knew?

Can anyone say me what’s the code to create horizontal arrangements?

I guess you can find the name by dragging the component block for instance List_View1 and do a do it on it. It is always the latest block in the menu. You get a text like Do It Result: com.google.appinventor.components.runtime.ListView@c1e81ee You can see that you will need to use the part that contains ListView when using this extension. or Do It Result: com.google.appinventor.components.runtime.WebViewer@5d27bdd you need to use WebViewer with this extension.

Hi, i just used this extension and on Ball & ImageSprite Speed porperty doesn’t work!
To explain further i set the ball property for speed to 5 i got no errors but the ball doesn’t move!
any suggestions?

[sonumohammad333 (Sonu Mohammad)]

If I delete the main layout, do the components inside get deleted?
Can I use the ids again?

[yusufcihan]

@sonumohammad333

do the components inside get deleted?

No. You need to delete them too.
