Flex :: Changes To Mxml Not Reflected In Browser

Oct 7, 2009

I have a Flex project and am using a trial version of Adobe Flex Builder 3 to build it.

I do the following:

1. Change an mxml file in the project (for simplicity, assume I changed the text in a label).

2. Right click on the project, Export, Release Build

3. Right click on the main mxml file, Run As -> Flex Application

A browser window opens, everything runs fine, but I cannot see the change I made in step 1.

I thought the browser (tried with IE, Chrome) might be caching stuff, so I tried after deleting all temporary internet files, but I see the same behavior.

Flex :: ItemRenderer Hieght (and Height Changes) Not Reflected In AdvancedDataGrid Row

Sep 14, 2011

I have an AdvancedDataGrid with variable row height set to true.I have written a cutsom item renderer based on the DataGroup spark component. Each row in the grid has multiple entities to display, the x position and width of the entites are based on the data of the entity itself.I have a custom layout written for the DataGroup that measures and posistions each entity based on its data. Each entity in each row can either truncate or not truncate its label. When the labels are not truncated, I calculate the actual width of the object and validate its size manualy (to force the label to have the correct width and layout all its text lines and remeasure itself) within the DataGroup's Layout's measure method to accurately measure the datagroup itself.The layouts, measuring, sizing, display, etc all work correctly. The entitys report the correct height they need when not truncating the labels, the datagroup reports the correct size it needs to draw all of its row's worth of entities (all from measure methods like they need to under the UIComponent lifecycle).When inside the AdvancedDataGrid itself, rows are not sized correctly. The majority of the rows do not require multiple lines and display just fine. Those that require multiple lines have larger row heights, but not large enough to accomodate the entire text in most cases. The DataGroup for that row (and its itemRenderers) are clipped. Furthermore, When scrolling the grid, every row scrolled onscreen is the default 1 text line height, irregardless of data.In any case, resizing the AdvancedDataGrid (not resizing its columns, but the grid itself) forces all rows to snap to the correct desired height.Scrolling again produces incorreclty sized rows.

Additionally, the layout of each entity in the row is determined by several external factors - most commonly being visible range (along the horizontal). Changing this visible range will trigger all item renderers to resize themselves (through the custom layout class) to their new sizes and remeasuring the new DataGroup layout. This actually triggers a custom hierarchy parser which rebuilds all the ArrayCollections used inside the AdvandedDataGrid data provider, so ArrayCollections are dispatching change events that each row's DataGroup reacts to, so the DataGroup itself is invalidating its size and layout.These resizes do not trigger the AdvancedDataGrid to remeasure its row heights, and I must rezise the ADG itself again to snap the rows to the correct height.Anyone have any experience with dynamically sized rows in an AdvancedDataGrid or ItemRenderers which must forcibly make the AdvandedDataGrid re-layout its rows?

Unfortunately, I cannot provide source code as there are a huge number of classes going into this, hierarchial data, rolling up closed nodes into multiple rows, custom hierarchy parsers, a multitude of item renderers - that and its a Government contract.I have run into a similar issue with a much simpler item renderer, basically a label that will respect a max height, resize itself upto that height as its wordwrapping data will require, and then create scrollbars for itself. Again, the data sizes almost correclty when the grid is created, then changing the column width within the grid does not resize the row height as the item renderer adjusts to its new width. Only in resizing the grid itself do the item renderers resize correctly, create scroll bars, and the grids row heights are correct.The source for that item renderer:[code]Very wide column, no scroll bars, the labels measured height is shown in the row height.Smaller width column, some renderers have hit max height and are creating scroll bars, the last renderer is still using the measured height of the label.Smaller still column, all max heights are hit and scrollers are present for all labels, scrollers will select the row when used but allow scrolling so all text is viewable.

Flash :: Flex :: AS3 Vs MXML - Compilation Speed Difference And How Does The Mxml Compiler Work

Sep 24, 2009

Does MXML get compiled down to as3 and then converted to flash bytecode? Also, is there a significant performance penalty to compiling mxml vs compiling as3?

Flex :: MXML Syntax To Assign Properties Of Subcomponents In Custom MXML Components?

Jun 4, 2011

I am working on a custom Flex 4 component which is an aggregation of two existing flex components. I would like to be able to specify my own custom properties for the component as well as access the existing public subcomponent properties via MXML. For instance I might want to adjust the font color or style for the label and text input. toy component which aggregates both a label and a text input:

<?xml version="1.0" encoding="utf-8"?>
<s:Group xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"

[code]....
