Re: [flexcoders] domain problem in remoteobject application
You can configure in amfphp where your 'services' would be. Take a look at documentation, I think that your idea is to have just one amfphp directory for every project, if so, You can reference external directories in a way that amfphp would search for them.

[flexcoders] The Blueprint Eclipse plug-in is live on Adobe Labs
If you get a minute, please check out Blueprint, which we released on Adobe Labs a couple of weeks ago. Blueprint is an innovative code-centric search application, initially delivered as an Eclipse plug-in. It is a custom search tool that searches only for code (for now, it searches just for MXML and ActionScript). So, for example, if you search for DataGrid, it returns a set of code examples that use the Flex DataGrid control. But what's really cool is that you can easily highlight, copy, and paste chunks of code right into your application, all without leaving Flex/Flash Builder. For more information, see the Blueprint page (http://labs.adobe.com/technologies/blueprint/) on Adobe Labs (FYI, Blueprint now works for Flex Builder 3 and Flash Builder 4) Regards, Randy Nielsen Flex Doc Manager

Well I will use mx:UITextField if faster... but I have to use custom itemrenderer because of complex data to display. The scrolling I described occurs only on mousewheel, and there's no scrollbar.

Thanks Ian, that gets me closer, but it doesn't quite work because, I get the
error, Can't find single subsection with title:Assumptions - because not
every subsection will have one with that title - that topic is only in certain
subtopics. The XML it needs to be inserted into looks like this:

subsections
subsection title=Technical Constraints/

module title=iDesign orderID=1.00
subsections
subsection title=Assumptions/
/subsections
/module
module title=iBuild orderID=2.00
subsections
subsection title=Assumptions/
...etc.
So there are some subsections that have one with a title of Assumtions, but
you'll see the first module's subsections doesn't have one. Trying to figure
out how to account for that withouth getting null property errors. Any ideas?
Thanks, you've given me some good stuff to work with so far!

Wait - I figured out I was not adding in the topics / node. So I am almost
there now, this is working, EXCEPT the code only inserts one topic per
subtopic, even though there are more row nodes that are tagged to the same
subtopic in the same module. If more than one topic belongs to a topics node,
it gets overwritten, so only the last one found is inserted. The code as I have
it now (thanks Ian) is:
for each (var contentRowItem2:XML in _contentXML..row)

var topicXML:XML = new XML(topic /);
topicx...@title = contentRowItem2.LinkTitle;
topicx...@author = stripSharepointPoundTag(contentRowItem2.Author);
topicXML.overview = new XML(overview /);
topicXML.overview = contentRowItem2.Overview;
var modulesList:XMLList = finalXML..module.(@title == moduleName);
modulesList[0]..subsection.(@title==contentRowItem2.Subsection).topics

Hi Alex, Thank you for your suggestion. I did use profiler to check, and yes, it was rendering of post that is taking most of the time. I did my best to make the render as light weight as possible by extending from UIComponent, but as you can see, the post render did not only include text and pictures, it also included a list of comments.(List within list, or list control inside another list's itemRenderer...I hope this is not too confusing.) You may be right that the post renderer is inefficient, but I think there is just too much going on in one post render.

Each post will have variable height due to different content and different number of comments Currently, I put 50 posts in a vbox, and the vbox height is set to 768. The vbox wil have a vertical scroll bar for user to scroll down to see the older posts. Since vbox will render everything before the component can be visually displayed, I can understand why it takes such a long time. I have tried to modify the code to use variable height List with custom itemRenderer instead, but the scroll on the list is NOT smooth at all due to itemRenderer recycle and re-render with new data. I am running out of ideas now. Many sites(facebook, blogger, or any other blog site) made this easy with PHP/.NET/HTML utilizing div+AJAX, but what is the best approach with Flex when constructing a blog engine application? Any suggestion/help will be greatly appreciated. Thanks!
[flexcoders] Re: Performance improvement recommendation
One thing the OP might want to try in addition to lightening the repeated components is to use a repeater and start out by just loading 5 (or however many are visible without scrolling), and then add to the collection after those are drawn. Amy, thank you for your suggestion. I have one question which is related to UI design based on your suggestion. Let's say I have 50 posts to display. I only display first 5 and add rest of the posts after the first 5 are drawn. By doing this, if a user want to see older post, let's assume post number 46~50, the user should scroll down by using the vertical scroll generated by repeater. Doesn't the user still have to wait for a while before the vertical scroll bar is seen since repeater will need to render rest of posts before the vertical scroll bar can be generated correctly? Currently, I am implementing paging as a temporarily solution(5 posts per page), but I really prefer to squeeze in as many posts as possible initially. --- In flexcoders@yahoogroups.com, Amy amyblankens...@... wrote: --- In flexcoders@yahoogroups.com, Alex Harui aharui@ wrote: Use the profiler to see where the time is being spent.

[flexcoders] Re: Set the height of a custom itemRenderer to its children
Thanks for the response, droponrcll.
Actually, if I just had the VBox only that would have been fine, but my VBox is
actually an itemRenderer for a List control. The List control is automatically
scaling the width and height of the VBox to 100% of the List controls' row.
Any idea how to get around this? Thanks.

[flexcoders] Re: htmlText truncation when changing from embedded to device font
I'll let the engineers let you know why this is happening. But, you can
get it to work with the following steps (hack):
1) Remove height=200 from the test Text control.
2) Add this function:
private function updateTextSize():void
{
test.invalidateSize();
}
3) On the ComboBox change event, execute callLater(updateTextSize);
Note: If you use embedded fonts, a boldface font must be available for
b/b to work.

Hi all,
I've seeing some strange behaviour with a mx:Text component using
htmlText.
It seems that when the fontFamily of the text component is changed at
runtime from an embedded font to a device font (or vice versa), the
content is truncated, and the HTML formatting lost. However, when
changing from one device font to another (or one embedded font to
another), it works just fine.
Take this example (view source enabled but without the actual font
files included - any OTF should work fine):
http://dev.nx.sg/lab/fontchange/FontChange.html
This app initializes the text component with some htmlText using a
device font (_sans in this case). Once loaded, try changing the font
to another device font (e.g. Courier New or Myriad) with the dropdown.
Everything's fine. Now change to an embedded font, and note the
truncation and loss of formatting.
The reverse happens if I initalize the field with an embedded font -
changing to another embedded font works fine but changing to a device
font ends up truncating again.
Anyone got any ideas how to make this work?
Thanks,
Toby.

RE: [flexcoders] Need help tranforming some XML
... break that long line of E4X into separate components...
I am with you here. Do it one step at a time and check each step with a
trace(xml.toXMLString()). If you really like concise, hard to read code,
you can squash it back together once you get it working.

Hi Jason,
Stepping through it, it works when you break that long line of E4X
into separate components.
(For some reason people seem to want to write really long E4X
statements - I'm not quite sure why...)
Like this, your loop works.
for each (var contentRowItem:XML in _contentXML..row)
{
var moduleName:String = contentRowItem.Module;
var topicXML:XML = new XML(topic /);
topicx...@title = contentRowItem.LinkTitle;
// This e4x creates an XMLList, so pull off the first entry
var module:XML=finalXML.module.(@title == moduleName)[0];
// Likewise
var
topics:XML=module..subsection.(@title==contentRowItem.Subsection).topics[0];
topics.appendChild(topicXML);
}
However - I'd include a bit of error checking for those XMLLists...
for each (var contentRowItem:XML in _contentXML..row)
{
var moduleName:String = contentRowItem.Module;
var topicXML:XML = new XML(topic /);
topicx...@title = contentRowItem.LinkTitle;
var modulesList:XMLList=finalXML.module.(@title == moduleName);
if (modulesList.length()!=1)
throw new Error(Can't find single module with title:+moduleName);
var topicsList:XMLList=
modulesList[0]..subsection.(@title==contentRowItem.Subsection).topics;
if (topicsList.length()!=1)
throw new Error(Can't find single subsection with
title:+contentRowItem.Subsection);
topicsList[0].appendChild(topicXML);
}
My general approach to this type of stuff is: break it down. Store and
trace out each part of your e4x statement in a separate variable, bit
by bit. That'll show you where it's going wrong.
HTH,
Ian

SubsectionTechnical Constraints/Subsection

What I need to do, is take it from that flat form, and based on the
values
of some of the nodes (Module,Subsection, and Topic values), make new
more hierarchical XML that is based on the Module, Subsection, and Topic
values in the XML, so that it looks like this:
xml
modules
module title=iPlan orderID=5
subsections
subsection title=Assumptions
topics
topic title=Starting
iRequire
overview

iRequire, you will first need to do a
/overview
authorSanders, Larry/author
/topics
subsection title=Project Information/
/subsections
/module
module title=iDeliver orderID=6
subsections
subsection title=Assumptions/
..etc.
I have it assembled this far, where the module nodes are created just
fine,
and the subsections are appearing under the right module with the right
title attribute:
