In MXML Flex, you can use {} to bind data. In AS3, how do you bind data? For example, I have a text input box and when I click the Submit button, it writes the text of the the input box into a child node in an XML file.
View 2 RepliesIf 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.
I have a form that consists of two data grids and a button. Datagrid 1, "myStaticDataGrid", has values I have added for the user to select from. I want the button's click event to send the current selection of myStaticDataGrid to the second datagrid, "myDataGrid". I have been able to accomplish this if I use a text box and a datagrid but I am having trouble finding the right syntax to grab the selection data from myStaticDataGrid.This is my attempt using the two datagrid approach:
<s:Form id="myForm">
//The values from this grid are determined once the button is clicked.
<s:FormItem id="myDataGrid">

View 1 RepliesI have successfully loaded and parsed the XML data that I need. I would now like to build a dynamic symbol that displays the data. It is a list of managers. I would like to display their names, organizations, etc... I assume a label would be best, binding the appropriate XML node to the text attribute of a label? I'm not sure, but that sounds the most reasonable. I can't seem to find and examples of doing this in AS3 however. Does anyone know how I would accomplish this task?

In 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:
<mx:DataGrid id="dgReport" dataProvider="{rptReport.currentItem.report}" rowCount="{rptReport.currentItem.report.length}">

I'm working on a major Flash project that is going to be the core content of a site. As most of you well know, almost any site can be entirely copied by copying the cached files and the hierarchy (files and folders structure), and it would run without problems on an Apache server with PHP enabled, if used. What I would like to know is: How to bind SWF files to run on a specific host?
The SWFs will be encrypted, so outsiders won't have access to the methods used to stop the SWF from running on a different host, question is: what method to use? I think the solution could be hardcoding the host IP inside the SWF, so if the SWF is looking for 123.123.123.123, only a host with that IP would allow the SWF to run further. The issue is that AS3 alone can't discover the host IP or could it if it's trying to load a resource file? Can you secure your swf so it checks if it is running on a recognized environment?

1. I've installed FMS on OpenSuse 11.4 64 bit, I know that according to the requirements it is not recommended distribution, but common opensuse is very modern and complete.
2. During the installation I had to make a link @libcap.so.1 into the directory where installFMS script was present (because installer says that there is no libcap library which is not true)
3. Completed the installation without installing apache (I have apache on this machine but disabled -> free 80 port)
4. I have left default configuration (regarding user, group, ports: 80 & 1935 + 1111, added the admin user)
5. I started the server with the command ./server start

For example i need to add onclick url, because there isn't built in url on click.

Parameters to be sent to the HTTPService are passed to the component. This is working fine.
