Re: [FlexJS] Data-binding fails when following multiple references

[sankar]

Hi Piotr,

Sure, if we need to move early (than you fix) we'll probably need to move
with the basic proven way of binding (to tab type of components). But I'm
afraid some of the application here based on rendering dynamic data. Thus
tabs and some other items shall be drawn after data available to the
application. I shall check if BasicBinding can address this requirement than
ConstantBinding.

Thank you, Priotr.

Hi Priotr,

I'm okay with adding only one model class in  tag. I also tested
if I declare an external class having data for Table component in
 tag and then bind to Table component, that does work. 

But Tabs and TabBar component still breaking my application when I tried by
bracketed binding. I tried following codes:




   






































Can you please take a look, Priotr (?)

Thanks!

Re: [FlexJS] Data-binding fails when following multiple references

[piotrz]

Hi Sankar,

I did look into that. Here where the problem is. We have tag  - which
looks like can contains only one model. Once you declare:






After compilation only the last one was picked up and put into the strand.
Since you were used the first one Binding was not seen it cause only the
second model exists. 

Put into model only one model and it should work.





I'm not sure whether this is bug, but in my opinion it is good that you can
put there only one model. It at some point forces you to build small views
with small pice of data source.

Let me know whether this is working and I will resolve jira.

Thanks,
Piotr

Hi Piotr,

I've created a JIRA issue pointing bracketed binding problems to MDL
components. You can find it at here:

https://issues.apache.org/jira/browse/FLEX-35256

Please, take a look.

Re: [FlexJS] Data-binding fails when following multiple references

[Carlos Rovira]

Hi Sankar,

IMHO, you should not introduce FlexJS components from HTML but the ones
that introduce simple tags like Span, H1, A, and so on...
Layouts in MDL are performed with layout components:

https://getmdl.io/components/index.html#layout-section

So the ones that we created in MDL library

The way js:Container works in FlexJS is setting some CSS styles (like
position relative) that are not used in MDL to position things.

The examples I'm seeing in MDL use normal MDL components for 80-90% of the
work while depend on some CSS rules for the rest 10 to 20%.

In my opinion, one thing we could do with MDL is to remove any HTML swc
dependency. And/Or separate basic html basic tags like span, a, p, h1
from the rest of FlexJS components like Container, Button or CheckBox

Re: [FlexJS] Data-binding fails when following multiple references

[Carlos Rovira]

Hi Sankar,

as Piotr said, let us know what you find. Our way to work on MDL was:

1.- Get all components in place and with exact HTML structure
2.- Get Flex Events work mapping MDL ones
3.- ... try example when see what's missing --> I think we are here right
now

So Data binding could be one of the things not working. There's examples of
binding working on MDLExample: List, Table, Icons, and more...
but at this time its ok some comps binding could not work

Thanks!

OK.  I will take a look.

But if you workaround it by using getter/setter and not a [Bindable] var,
does that allow the chain to work?

Re: [FlexJS] Data-binding fails when following multiple references

[Alex Harui]

OK.  There should be an array of 3 properties in the data binding
structure.  It shouldn't give up and create a getter function.  Then,
ViewDataBinding may need to detect that and use a ChainBinding.  It could
borrow code from ContainerDataBinding.

Re: [FlexJS] Data-binding fails when following multiple references

[piotrz]

No problem - "patient" - will be my second name :)

I just did small clarification for code in ViewDataBinding. I will commit it
along with this first fix for this jira.

OK, sounds like the generated code for [Bindable] on getter and setters is
broken.

I will take a look.

Re: [FlexJS] Data-binding fails when following multiple references

[piotrz]

Alex,

I just wanted to write it that compiled class doesn't contains it [1].
Additionally what is funny - debugger do not stop when generate setter is

ClassA.prototype.set__fieldA = function(value) {
  this._fieldA = value;
};

but it's do work when I have following

ClassA.prototype.set__fieldA = function(value) {
if (this._fieldA != value) {
  this._fieldA = value;
}
};

Yes, or just remove the

It may no longer be needed.  I've been wondering if it is needed.  I don't
think ContainerDataBinding has such a check.

Thanks,

Re: [FlexJS] Data-binding fails when following multiple references

[Alex Harui]

Hi Piotr,

In the code you posted links to, fieldA has a getter marked with
[Bindable].  The compiler should output code that converts ClassA to
extend EventDispatcher and wrap the setter to dispatch a valueChange event
and then things should work.  If that isn't the case that would be where
the bug is.

Thanks,
-Alex

Re: [FlexJS] Data-binding fails when following multiple references

[piotrz]

Alex,

Answer for you second question - "fieldA" do not dispatch "valueChanged"
event. If I have to dispatch it manually from setter I will need also extend
my simple VO class by Dispatcher. 
I doubt that is the case.

Re: [FlexJS] Data-binding fails when following multiple references

Alex,

I was also thinking that it shouldn't necessary be in that case generic
binding, but again it is all about condition. 

In case of ViewBinding condition is 

if (binding.source is Array
&& binding.source[0] == "applicationModel"
&& binding.source.length == 2 && binding.destination.length == 2)

binding.source[0] is not "applicationModel" and later watcher map is being
created from that model. I'm not sure whether I can add another condition:

if (binding.source is Array && binding.source.length == 2 &&
binding.destination.length == 2) 
//and then create simple binding

I will try, but if this can be a fix ?

In a chain of bindings (a.b.c) the binding system is supposed to generate
watchers for a, for b, and for c, since you can change c without change a
or b, or change b without change a, or just change a.  The binding system
generally has to be careful and watch everything.  That's one reason
binding can be slow and heavy when you know you will only change a or c
but not both.  That's why in FlexJS binding is implemented as a bead.
Folks can swap in different binding implementations if they need to
optimize for only a changing or something like that.

If you use [Binding] the compiler will generate the code that dispatches
events, but if you use [Bindable("eventName")] then you have to choose the
right time to dispatch the appropriate change event.  In ItemRenderers,
for example the "data" property never changes once the renderer is set up
so there is no reason that an item renderer "must" dispatch a change event
in the "data" setter, although I think some renderers do it so folks can
hook it in MXML.

Really, binding is just an automated way of listening for change events.
Which events to "must" listen for depends on your actual scenario, but the
binding beads are going to "aggressively" listen for every possible change
even though sometimes they don't need to.

I didn't see this until I'd already replied.

So when you dispatch "valueChanged" and had [Bindable("valueChanged")] on
anyClass you were telling the binding system that anyClass changed when
really, the instance of anyClass did not change and only fieldA changed.
And the binding system worked.  It saw the change event and updated the
binding (although it occurred to me just now that it should have created a
SimpleBinding instead of a GenericBinding).

For this view, if you use just [Bindable] on anyClass, I'm not sure what
the compiler will generate, but it probably doesn't matter since the only
thing changing is fieldA.  When fieldA changes, a valueChange should be
dispatched and picked up by the PropertyWatcher and that should cause an
update of lbl.txt.  So the question is, did the code for fieldA dispatch
an event and did PropertyWatcher see it?

Thanks for digging into it.
-Alex

Re: [FlexJS] Data-binding fails when following multiple references

[Alex Harui]

Hi Piotr,

If I understand correctly, this example is working as expected.  When you
use just plain "[Bindable]" the compiler will generate getter/setters and
dispatch "valueChange" events for you.  When you use
"[Bindable("someEventName")]" you are responsible for dispatching that
event somewhere in your code.  The compiler will not change your code.

Understand, so it is probably the way we should go, but for sure you don't
need to extend your VO class by EventDispatcher.

This investigation helped me with your issue with multiple references. I
will be investigate it farther later today.

This is how field binding to UI component has demonstrated in the example(s)
that supplied within Apache FlexJS SDK. I followed that only; And I vaguely
remember, the way of implementation only worked for me. If I remove the
event dispatch on field's SET method, change do not reflect to the UI
component that the field bind to (at least with my present nightly build
0.8.0 code that I updated some days back).

Re: [FlexJS] Data-binding fails when following multiple references

Actually the above scenario was always working in my tests also, previously,
when you binding a field to an UI component in single reference way, i.e.,
{anyClass.fieldName}*"/>

But, this never works if you the field name comes after multiple references,
i.e.,
{anyClass.anotherClass.fieldName}*"/>

Piotr, your tests shown the binding in a single-referenced way, but it fails
in multi-referenced way.

Re: [FlexJS] Data-binding fails when following multiple references

[piotrz]

Alex, Sankar,

I did some investigation. Here is where I'm now. I did simplification of
Sankar's code. Some things is no needed in my opinion and binding should
works. 
Code:
VO -> https://paste.apache.org/UVh7
View -> https://paste.apache.org/GI5n

After compilation _bindings array look like that ->
https://paste.apache.org/m5oA

ViewDataBinding checking the condition and decide that will create generic
binding - execute -> makeGenericBinding. Inside it's create PropertyWatcher
object who is registering on "valueChanged" events.

VO for fieldA has some default value. ("Change Value..")

- When we have first initialization of this ViewDataBinding function
"makeGenericBinding" do his job - Register PropertyWatcher. Inside this
class call: parentChanged (registration for "valueChanged") and update
bindable property by "updateProperty". - Init is OK.

- I'm changing something in my TextInput and "onTextInputChangeA" has been
called. 

1) Binding is not working: getter "anyClass" is being fired, but no changes.
2) If I dispatch commented event "valueChanged" - PropertyWatcher class is
properly calling "changeHandler" function and Binding is working fine.

First questions:
- Should we have a BUG or maybe this is how it works in FlexJS ? 

I will go farther with this, but I'm trying to think loudly to get some help
on this one. I will attach to jira changed example with pom file.

Piotr

Unfortunately, that didn't worked for me. You probably put all the codes in
 file; My codes are all in a separate view and called into
 in main application file. I tried to put the
 tag in my View file (which I tried already in
past) but that didn't helped. Nor if I put the tag in main application file.

I'm not sure about the above point. Both of my demonstrated classes doing
set/get to it's field, which dispatching change event also - don't I need to
extend EventDispatcher? I haven't made any changes to my classes yet, but if
that is a gamechanger then please guide me.

@Sanker,

I checked the same scenario with minor changes. You need to use bit more
code to achieve the binding in FlexjS. use following code to achieve correct
binding behavior,

[Bindable] privatevar anyClass:ClassA = new ClassA(); 
protected function onTextInputChangeA(event:Event):void 
{ 
anyClass.fieldA = myTI1.text; 
} 

protected function onTextInputChangeB(event:Event):void 
{ 
anyClass.subClass.fieldB = myTI2.text; 
} 
...

How are the three elements defined?  IOW: what is anyClass, a variable, a

Where there any warnings in the compiler output?

[FlexJS] Data-binding fails when following multiple references

[sankar]

Hi,

I've reported this issue to JIRA at:
https://issues.apache.org/jira/browse/FLEX-35227.

Basically, binding to UI components do not works when following multiple
class references. i.e. following thing should work:

**

But this won't:

**

Even if both the fields (fieldA, fieldB) has it's binding prequisites, i.e.
/[Bindable("fieldAChanged")]/ etc. metadatas.

The JIRA issue has been supplied with a basic project/example to demonstrate
this problem. I was wondering if it's something that needs compiler level of

Thanks!
