[flexcoders] Re: better option than repeater?
OK, thanks to the below example, I have made some progress on setting up
my first custom itemRenderer. Code can be viewed here:
http://www.ubeek.com/Flex/testrend.mxml
As I mentioned before, my goal is to display a list of Staff. One of
the fields (moduleAccess) in the Staff record is a list of integers
(i.e. 1,3,17,25). I have a table that contains a list of modules
(SEQ, MODULENAME). For each Staff displayed by the List's itemRenderer,
I need to loop through all the modules and output a checkbox...and if
the module's SEQ is in the Staff's moduleAccess list then the box should
be checked.
I tried setting up a remoteObject inside the custom renderer, but no
matter where I put it it gave me a parse error. I guess it doesn't like
mx:RemoteObject inside a component. So I put it outside the component,
but then the script function inside the component didn't seem able to
access the RemoteObject's data. Although it was what I initially tried
to do (with the RO inside the component) I don't really want to do that
as it seems highly inefficient to query the database for every Staff
record. It seems I should be able to execute the RO just once and then
pass the resulting list of modules to the component so I can loop
through it to output all the checkboxes (and for each record check the
SEQ against the Staff's moduleAccess, which I know how to do).
So the question is - how do call the RO just once and pass the result
into the component (as an ArrayCollection or something) so I can loop
over it repeatedly instead of actually calling it and hitting the
database repeatedly?

[flexcoders] better option than repeater?
I don't like repeaters. They are too clumsy. The biggest drawback is an
inability to access values after the repeater has finish executing. It's not
the same as, for example, looping over values and generating static HTML using
ColdFusion. I seem to always end up having to navigate up and down through the
parents/children of the objects and storing values I need in properties like
name, automationName, etc. This is clumsy and messy.
As an example, I have a section of my application where I want to list the
names of people from a table, and for each person generate a set of checkboxes
that designate access to certain areas of the application. For example:
http://www.ubeek.com/images/staffrepeater.jpg
That is one main repeater that loops through the staff (records returned from
remoteObject) and inside that repeater two other repeaters (also from
remoteObjects) that generate the checkboxes.
I can't simply pass the primary key of the staff for which the Save button was
clicked, by putting click=saveClick({staffRepeater.currentItem.SEQ}) into the
button object. When I do that and click it I get an error about repeater is
not currently executing or something like that.
I don't want to resort to a datagrid and then click to edit then bring up a
form kind of process. I want it as few clicks as possible.
Is there a better way to display data in a custom way like this, without using
repeaters, so that I can more easily access the child objects and their
properties?
Thanks,
Paul

Thanks for the example. I know that I could make certain things a lot easier

Hopefully this will get me started and I'll get it figured out. I know it
would simplify my code - there are many places where I repeat the same kind of
display, with different data, and so far just write functions that are result
handlers from remoteobjects and the functions spit out the objects I need and
addChild them. At the moment I am a bit mired in the repeat over a recordset
and spit out code mode of thinking, thanks to years ColdFusion, Perl, asp,

[flexcoders] ColdFusion service restart not picking up new LCDS destinations
I added a couple destinations to the data-management-config.xml file and restarted ColdFusion. My Flex app gave an error that the destination was not found. I restarted and tried again, same thing. Did this a few times and nothing. Then I went in and add a single space to the xml file, restarted the service, and it picked up the changes. Any idea why this would happen? Also, is there any way to make it so I don't have to restart the CF service in order for it to pick up changes to my CFCs? Thanks, Paul

[flexcoders] bind one arraycollection to another
I have an arraycollection that has two columns. the second column actually stores an object that has properties on it. I want to put those values into a second datagrid. Can I do this using binding? I was able to use a loop to fill the second arraycollection, to which a datagrid is bound, by triggering the loop function from the first arraycollection's collectionChange event. However, I don't like this approach because it'll probably cause issues with selectedItem on the datagrid (removeAll then repopulate would throw it off), as well as a noticeable flicker when dealing with a large dataset. If there's another format for the second column in the first arraycollection that would work better than an object, I'm open to that too.
[flexcoders] Re: bind one arraycollection to another
The object is being passed to the first arraycollection through LCDS, and in
the CFC I am creating a struct. I have no problem with the idea of converting
it to another data type such as an XML string. The problem is I can't bind it
to one ROW and column, I need to bind it to the second column of all rows -
basically the first grid is the primary key in column one, and the property
with all other columns and values in the object.
If I have a row selected in the second grid, or it's sorted or filtered in some
way, and I do a removeall and then repopulate it...what will happen? I suppose
I can store the sort, filter, and selectedIndex, and then reapply them after
the refill - but I want to avoid any kind of flicker that the user would see.

[flexcoders] Re: create class on the fly
I cannot predict at compile-time what the name (or properties) of the class will be. I need to CREATE the class at runtime, AND add the properties to it. It seems, so far, that this is not possible. However, what I'm doing sounds very similar to your project. It's not so much the sheer number of tables (although a few dozen) but the fact that the application allows the creation of new tables (so I need a new class) and columns (so the properties might change). I can easily have my app write new destinations to the config file for any new table created. I can even write the necessary CFCs to disk based upon schema changes within the app. But I cannot find a way to get the classes I need. All tables share the same foreign key column name, which is helpful. My idea is this...set up one class that has two properties - the foreign key and a second column. I would have one destination for each table, but all destinations will point to the same class. When my CFCs pull data, I will have them return the primary key along with all other data encoded (XML or something) into the second property. Then on the client side I can manage it by filling an ArrayCollection, then having a function that parses the actual columns and rows (from the second property) into a second ArrayCollection that my datagrid is actually bound to. Creates/updates would go in the reverse direction - placed into the second ArrayCollection and then processed up to the two-property format for the first one, at which point LCDS will take over.

[flexcoders] Re: create class on the fly
Thanks for pointing me in the right direction. I had no idea how well passing Flex Objects and CF Structures back-and-forth works. It's so simple, and CF Structures are fast. At the moment it displays object [Object] in the grid :-) but I'm able to bind a form to the properties of the object in that grid column, which is pretty cool. I'm a couple small steps away from having the complete solution I have been looking for: using LCDS with multiple tables but only ONE generic class. Here's a bonus question. Within a data service can you have subtopics like you can have for messaging services? If so, then I'd be able to get away with having only one destination. Otherwise, I'll need a destination for every table, but that's not such a big deal. --- In flexcoders@yahoogroups.com, jer_ela g...@... wrote: Just have your cfc return the results as a query, or as an array of structs. The first will be converted into an ArrayCollection of generic objects in Flex, and the second into an Array of objects. Each of these objects will have a property for each column in the record. Flex will be quite happy with these object and will let you do pretty much anything you want to do with them. You can use for (var key:String in recordObject) to get the property names. Since your queries are going to be dynamic you are going to have to process them dynamically and this is how you do it. You could also have your cfc return metadata about the result set, to tell you which properties are the primary keys, and anything else you need to know about the result to process it correctly. Having the server return objects that automatically get converted to typed flex objects is great when you know what type of objects are going to be returned. But if you don't Flex can handle untyped dynamic objects just fine, and you should use them when the results of a service can't be known at compile time. --- In flexcoders@yahoogroups.com, postwick paul@ wrote: I cannot predict at compile-time what the name (or properties) of the class will be.

[flexcoders] Re: create class on the fly
Yeah, I saw your post in my hours of Googling last night. Seems very promising. The idea is to have a database table that stores a list of classes and their properties, and instantiate them at runtime without having to recompile the app - so that if a new class is added to the db my app can use it on the fly. Would your method of using Modules solve this? It appears so, but I haven't had a chance to try it out.

[flexcoders] LCDS without a class for every table?
OK, so I was the one looking for a way to do classes at runtime. The bottom line is I want to use LCDS because it's, well, fantastic. However, in my app I cannot know at compile time all the tables (and columns in them) that will need to be accessed. Is there a way to use one single class which has a property on which I attach an object that contains the properties I need (probably in XML format) based on the table that should be updated, then modify the CFCs so that they extract the data, create/update/delete the correct table, and then pass the necessary information back to LCDS so that it pushes the update out to the clients? On the datagrid side, instead of binding the grid to an ArrayCollection, I could bind it to a function that parses the XML property on the returned ArrayCollection and returns a new ArrayCollection (or populates a second one) with the correct data for the grid. Does this sound reasonable and doable? Is there any other way to use LCDS without having a class for every single table? Thanks, Paul

if you just did dataGrid.selectedItem then that would be the selected row. add
[columnname] to get to the column, so:
dataGrid.selectedItem[columnname]
it's not the label, it's the data column name.

You can't use selectedItem because there is no selectedItem. You haven't
clicked a row. Try looping through the grid.
In the end, I really don't understand why you don't do this in the
dataCollection, or even in the source data.
for (var i:Number = 0; i mygrid.numChildren; i++) {
if (mygrid.getChildAt(i)[Kind] ==

mygrid.getChildAt(i)[Profit]

[flexcoders] Re: This is not as easy as it seems ... apparently...
That'll update the value of the cell.
You can't do what you're trying to do. You can't have a column with a
different dataField per row. The dataField for the column is the same for
every row.
Is this data coming from a database, through a view? You really should do this
there. You can set up a view column with an if/then that returns the column's
value you want.
