View 1 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:

View 1 RepliesFlex - Degrafa States Memory Management?
Nov 10, 2009I was recently profiling my application that uses Degrafa States in the skins and noticed that doing so uses more memory than I expected. Between the SetProperty and State, they were using about 10% of the total used application memory.
Would it be better to use css for the state changes and a new skin for each state? or Are there some simple tips to reducing the memory footprint of degrafa?

Flex :: Spline For Non Differentiable Function?
Jun 16, 2009I have a function that sometimes is non-differentiable at a point. When I now use a spline (Bezierspline in degrafa) for interpolation the interpolation at this point does not work as expected (at this point my function has a kink). Now when interpolating with a spline it draws some kind of loop around this point. I think this happens because the spline needs the derivatives of the functions which is not unique at this point.

View 6 RepliesFlex :: DataGridColumn Display Multiline String Data?
Aug 18, 2009Is it possible to display a multiline string in a Flex DataGridColumn?i.e. Display:
Text line one.
Text line two.
I've tried putting "
","
"," " when storing the string but nothing seems to work.Currently only "Text line one." is displayed and the rest is hidden in the cell. I would prefer not to use "wordWrap=true" to emulate this behaviour in the cell, but instead be able to manually put in newline breaks (although I could turn on wordWrap to avoid long text from hiding due to cell dimensions).
Flex :: Compare Data From DataGrid DataField With String Value?
Feb 16, 2012The question seems to be simple, however it create problems for me. I have a dataGrid with two dataFields: peerID, name. The information in a grid updated dynamically when new user joined the group (I'm creating a chat). I need that information about user deleted from a grid after it's disconnect. So, on "NetGroup.Neighbor.Disconnect": event i want to compare "event.info.peerID" value with all peerID values in a grid and delete info about disconnected user.
I'm trying to use next construction:
for (var i:uint, len:uint = txtDataArray.length; i < len; i++)
{
if (txtDataArray.source[i] == event.info.peerID)
{
[code]....
But it doesn't work at all!
I'v noticed that construction txtDataArray.source[i] (or txtDataArray.getItemAt(i) ) returned [object GridColumn] insead of value. So, I have two questions:
1) How to get the value of exact cell?
2) How to organized info delete after user disconnect?
