Flex :: Forms - Bind (two-way) An Integer To A TextInput Field?

Is there a different input type, or do I have to bind a different way?
View 2 RepliesFlex :: Data Binding Re-bind When Data Model Not Change, Possible?
Nov 4, 2011If user change the value of the TextInput, then click refresh button to retrieve the data model from backend again, the GUI value will not change back. Re-binding not happen, Since the value of data model not changed, no propertyChanged event fired.In this case, I must Programmatically set the model value to the GUI after data refreshing done.I know bi-directional binding can solve this problem(when user change value on GUI, set the new value to data model immediately). But sometimes I cannot use bi-directional binding, for example, the data model is a int, but user input a non-int value, I cannot set the value to data model. So the value in data model do not change, when refresh data, rebinding still not happen.
This will make the data binding useless. How to resolve this?I put pseudo-code here for now, I will put real code later:1. retrieve a data model from server, via blazeds or something else.2. bind the model to a TextInput on GUI.3. user change the TextInput text.4. User click a refresh button, triger retrieve the model value again.5. Now since the model value do not change, no PropertyChanged event fired.6. GUI value still is the user's input, not the value from the model. can clear the model value before set the velue back, make re-binding happen.(but sometimes you do not know how to clean the model value, take int for example, you may do not know the original value and happen set the same value). Or I can manually set the model value to GUI. But both are not good looking.

Flex :: Flash Builder - Datagrid Within Repeater - Data Bind Warning?
Jul 8, 2010In my Flex app I am using a repeater to show a report on my database data. On this report the user can "drill-down" on the data to show more detail. In order to make this easier on the eye I have a header label and then a datagrid within the repeater.Whilst this works perfectly, because the dataprovider for the datagrid comes from an array in the repeaters dataprovider, it is causing the following warning:Data binding will not be able to detect assignments to "report"The warning is for this line:

Flex :: DataGrid Reads A Field From LastResult.node As Number?
Sep 7, 2009Why does Flex 3 DataGrid read a string from XML lastResult.node as number?A field is saved as var_char in mysql, php reads it as string and pass it OK.If there are more then 16 charaters it gets rounded....For example:
this in database cell:
12345678901234567
gets read in DataGrid as nubmer as 12345678901234568
this is in database cell:
5555544444222223333377777
php reads it same and puts it in XML flex reads XML into arrayCollection and DataGrid reads it as:
5.55554444422222e+24
So it reads it as number, why? And how to make it read as String? I tried with labelFunction, no help.

Flex :: ItemRenderer As A Field Of `data`?
May 27, 2009I would like to let the data provided to a DataGrid decide how best it should be rendered (that is, let the data carry with it an object which will do the rendering).For example, by creating a "Renderable" interface, which has a 'renderer:IFactory' property, then used as below:
<mx:DataGrid x="0" y="0" width="100%" dataProvider="{myDataProvider}">
<mx:columns>
<mx:DataGridColumn headerText="Task" width="100"[code]....
But to do this, Renderable has to extend IEventDispatcher, which seems like a little much...I've also tried using:
itemRenderer="{(data as Renderable).getRenderer()}"
Which does nothing (in fact, the getRenderer method never gets called).Is there a better way to do this? Am I doing something fundamentally wrong?

Flex :: Override Child Node Controls In A Flex Tree Control?
Aug 20, 2010I am currently developing a dynamic LineChart in FLEX 4.I am implementing a Tree control next to my LineChart, which will filter the LineChart dataprovider and lineseries. The tree control has several branches and ultimately 5 children (leaf nodes) at the bottom of the last branch.I need the leaf node/children to be displayed as checkboxes inside the tree control.As I understand,this will require overrides in the TreeItemRenderer class.This is where I am a little confused on how to implement that.Currently I can distinguish between leaf and branches using this code, in my main MXML component.I added this because it may be helpful to some beginning FLEXdevelopers, such as myself, who cannot easily find this functionality documented well:
private function treeClick(e:ListEvent):void {
_selectedItem = Tree(e.currentTarget).selectedItem;
if(mainTree.dataDescriptor.isBranch(_selectedItem)) {[code].....
I am looking at the TreeItemRenderer override class from the following example here: In the example, they override the "createChildden" super function to add checkboxes to the tree control.My question is, can I override the createChildren function directly in my MXML component, and not have to use an entire class file to override this functionality? Must I re-invent the wheel to do this?Also, how can I distinguish that my treeItem is a leaf node and not a parent, in the override function? I only want to add checkboxes to the leaf nodes, how can I differentiate? The following example adds checkboxes to all branches and leaf nodes, but I want to add checkboxes only to leaf node/children. How would you approach that?
override protected function createChildren( ): void
{
super.createChildren( );[code]............
Here is my tree tag:
<mx:Tree id="mainTree" dataProvider="{treeData}" itemRenderer="TreeCheckBoxItemRenderer" labelField="@label" showRoot="false" width="100%" height="100%" itemClick="treeClick(event)" />

Flex :: Bind To Global Variables Inside Component?
Aug 19, 2009I've developed a component which is a combination of a few items (canvas, labels, etc...) but when I try to bind it to a variable such as: {stationXML.getItemAt(1).AAA.@value}, it doesnt work. Before I combined all the items in a component, they were all in the main MXML file at which time they worked. Not sure if it matters, but the "stationXML" arraycollection variable is declared inside the file "Station.as".
