[flexcoders] show data tips not working for datagrid
I'm trying to get a certain field to show up because it is clipped by the cell
in my datagrid.
I've set showDataTips = 'true' in the datagrid column that I want to show. I've
also set a dataTipFunction = showDetails on the datagrid itself and for the
column.
The function looks like this:
private function showDetails( item:Object ) : String {
var xmlItem:XML = item as XML;
return [EMAIL PROTECTED];
}
Nothing is happening though, no pop-up box, nothing. I am using an
XMLListCollection as the dataprovider for the datagrid.

[flexcoders] help with httpservice result as dataprovider for datagrid
I have a datagrid whose dataprovider is this:
mx:XMLListCollection id = experiments filterFunction=filter2
source={display_experiments.lastResult.experiment}/
I want to be able to double click on a row in the dg, which opens a pop-up
window where I can edit information and then update it.
The problem is, when I use change or collectionChange, I can't even click on a
row because it refreshes as soon as I try.
Not only that, but my results are not updated right away, it usually takes a few
updates to see the changes.
I have set makeObjectsBindable to true in my httpservice calls.
Thanks for any input on this

[flexcoders] convert e4x xml results to arraycollection or xmllistcollection
I want to filter the results (which are in e4x format) of an HTTPService call
(display_samples) and push certain ones into a new arrayCollection.
This code populates a Tree just fine:
mx:XMLListCollection id = all_samples
source={display_samples.lastResult.sample}/
But when I do this: Alert.show(all_samples.length.toString());
It's showing the size as 0. I can't seem to interact with the data at all. I
also tried an arraycollection and I'm making sure I set it after I send() the
HTTPService request.
These also don't work:
new ArrayCollection(display_samples.lastResult.sample)
display_samples.lastResult.sample as ArrayCollection
Any ideas?

RE: [flexcoders] convert e4x xml results to arraycollection or xmllistcollection
I ended up using a filterfunction on the XMLListCollection and it works like a

Here's the code if anyone's interested:

public function myFilter(item:Object):Boolean

[flexcoders] HTTPService updating database too frequently??
I have datagrids whose dataproviders are the lastResult of httpservice calls. The HTTPService calls are calling PHP scripts that update, remove, and create rows. I have a function that lets me double click an item in a datagrid and pop up a window which then lets me edit the info. The only problem is, the data doesn't always update right away even though I am explicitly calling a refresh method after every change. It sometimes works right away, then other times it lags and the change doesn't show up until I edit something else. Should I be doing this in a different manner?

[flexcoders] Problem populating datagrid after state change, need a Repeater maybe?
I have a form collecting data about an experiment. There's a numeric stepper that specifies number of repeated experiments there will be. Once the user enters all the data and presses submit, there's a state change triggered if the numeric stepper value is 1. I'd like the data from the form to be repeated the number of times specified and the only item that would change is the name of the experiment. These could also be text boxes that are editable so that the user can change certain aspects of each experiment. At this point, I can't even populate a datagrid manually.I also tried using a Repeater with no luck, I could only get the currentItem, it didn't generate multiple textboxes based on an ArrayCollection.

[flexcoders] Can editable row in datagrid depend on what node clicked in tree?
Now that I can determine what type of node was clicked in a tree (thank you Tracy!), I'd like to be able to edit that entity as well.. but in a separate datagrid. Right now, I have the viewStack selectedChild updating depending on what node was clicked. Is it possible to now initiate an itemEditing on the new datagrid that appears? (which contains certain nodes in the tree). Basically, as soon as I double click the node in the tree, I want the editable option enabled on that row in the datagrid that shows up. If that's not possible, can I at least set the selectedItem to the one I clicked in the tree? Of course the selectedIndex is going to vary between the tree and datagrid on the same item. Thank you.

[flexcoders] Custom components and handling variables
I'm still learning how I should be designing custom components and encapsulating methods/variables appropriately. I have a custom component that pops up and just adds/removes items from two arraycollections. After this is done, I'd like to close it and reflect the changes on the main application page. I'm just wondering how to access variables from custom components. Is this good practice or should these variables be initialized in the main application first?

RE: [flexcoders] Binding HTTPService xml to ArrayCollection for Datagrid
Ok after a lot of painful debugging.. I've found something strange.
Instead of an ArrayCollection, I declared myExperiments as an Object.
The XML format is like this:
experiments
experiment
title/title
machine/machine
username/username
/experiment
experiment
title/title
machine/machine
username/username
/experiment
/experiments
private function resultHandler(event:ResultEvent):void
{
myExperiments = event.result.experiments.experiment;
}
Then I set my dataprovider in my datagrid = myExperiments and for some reason
this works to display the experiments.
Why doesn't an ArrayCollection work?
Sorry for all the emails but this has been a problem for too long and seems like
it should be simple.

Datagrid
Still no luck.. I'm trying to check the length of the array and an Alert.show()
won't even display anything. Could it be order in which I'm executing
everything?
For instance, I can't call the display_experiments.php script until after a user
has logged in so it can query the database for his experiments.
I have a checkLogin function that sends the display_experiments HTTPService call
after the user has logged in.
What could I be doing wrong?

on return use
myExperiments = new ArrayCollection(event.result.experiments.experiment);
if expirement is the repeating element, then you need to use
(event.result.expirements)

The problem is related to the format of the XML I think. Here's a portion of my
php script (SQL statement not included).
$output = experiments;
while (OCIFetchInto($result, $row, OCI_ASSOC))
{
$output .=
experimenttitle.$row['TITLE']./titlemachine.$row['MACHINE']./machi
neusername.$row['USERNAME']./usernamedetails.$row['DETAILS']./detail
smonth.$row['EMONTH']./monthday.$row['EDAY']./dayyear.$row['EYEA
R']./year/experiment;
}
$output .= /experiments;
This works fine when using
display_experiments.lastResult.experiments.experiment.. but it does not work
when binding using a resultHandler as
[Bindable]
private var myExperiments:ArrayCollection;
private function resultHandler(event:ResultEvent):void
{
myExperiments=event.result.experiments.experiment;
}
And here's my HTTPService call:
mx:HTTPService id=display_experiments result = resultHandler(event)
url=http://localhost:8080/displayExperiments.php; useProxy=false
method=POST
mx:request xmlns=
username{username.text}/username
/mx:request
/mx:HTTPService
Trying to populate the datagrid with {myExperiments} doesn't work.
Do I need to output the XML in some other way?
Thanks,
Tanya

The datagrid doesn't even get populated and I'm making sure I actually send the
httpservice request on creationComplete of the datagrid itself.
I can drag ok when I use pseudo data that is not populated from the HTTPService.
I need the HTTPService to execute the php script which pulls the data off the
backend.

[flexcoders] Binding HTTPService xml to ArrayCollection for Datagrid
I have followed the example exactly as Adobe's book shows in Lesson 12 (Dragging and Dropping Between Two Datagrids) with no luck. I need to be able to bind the results of an HTTPService call (which executes a php script and returns rows in XML format), to an ArrayCollection or whatever datatype can populate a datagrid. Everytime I drag and drop between two datagrids I need to change this ArrayCollection. Any help willl be gretly appreciated please!!! Also, is it better practice to keep updating the database with every drag and drop, or to manipulate the ArrayCollection clientside, and when all's said and done finally update the database with one call?

Can you populate the source datagrid ok? Can you drag from the soruce to the target ok? Do you need the HTTPService for updating the back-end, of for getting data into flex?

[flexcoders] multiple click actions
I have a view stack which changes views based on whatever button is clicked on an application control bar... mx:Button id = myProjects label=My Projects click=myViewStack.selectedChild=projects; / As soon as you click 'myProjects' the view changes to a datagrid. But I also want to populate this datagrid by default as soon as it is loaded, I normally would have sent an HTTPrequest through that click action. Any suggestions?? I'm still very new to Flex and am getting used to basic architecture, whether to use state transitions or view stacks.. dynamically load components,etc... Is it necessary to make an HTTPrequest everytime I want to access/modify the database, and to have separate PHP scripts for every command?

RE: [flexcoders] multiple file upload and php problems
Yes, I fixed the problem.. I just had to find where in the flex the name of the uploaded file was. Now I'm trying to upload files to a remote server, but I think I will need to pass login credentials to it as well. Any tips on this?

I've tried very basic upload scripts as well as this one: http://codycodingcowboy.cahlan.com/files/php_fileuploads.html When I compile, I'm able to browse files, get the file size, but when I click upload or cancel I get [SecurityErrorEvent type = securityError bubbles = false cancelable = false eventPhase = 2 text = Error #2049] I guess I'm still unclear as to how the PHP is supposed to communicate with Flex if the script is not returning XML.
