Adding JS graph to Flex project
Hi, We have Flex + Java Web App. Needed to add Graphs to it, kind of a network of nodes, built from data coming from DB. Tried Birdeye Ravis, were not happy with it. So now we want to try using one of JS visual libs like VisJS or D3, possibly try to add AngularJS if it becomes necessary, which I doubt. Can I add such graph to Flex TabNavigator, inside NavigatorContent? Also where should I put JS code inside FlashBuilder project? Any pointers? Any good Eclipse 3.8 JS plugins? TIA, Oleg

Re: Profiling Flex/Java Web App
Alex, That profiler problem happens much before I reach my heavy duty popup with many children, on initial screen. We are making calls to about 30 Stored Procs to get proper permissions and load static data. (can probably turn off some of them and only use data relevant to screen with popup we need,although it might take time to investigate). As I said, Debugger is running fine, no timeouts whatsoever. Is Profiler more demanding than Debugger?

Profiling Flex/Java Web App
Hi, I have a large Flex+Java app (Flex 4.5.1). Created a new complicated screen (with 3 ADGs) and WindowTitle popup to edit a row with 2 sets of children (each is a DataGroup with Renderer, one is a few TextInputs (with 2 way binding), another is 2 dropdownlists (2nd gets a list based on 1st one selection, so there is a call to stored proc), checkbox and a button. It seems that if there are 100s of these children, it takes >35secs for that popup to come up in Edit mode. I tried to profile it using FlashBuilder 4.5.1 on Tomcat 6.0, but when I bring up profiler, it shows me popup "No activity happened in the past 60 seconds after connection was established with the application" and only after that app comes up. Debugger works fine, and I can run that app without any problems. Is there way to fix it? I have seen lots of posts showing similar error, but no solution so far. Please help! -- Thank you, Oleg.
DataGroup with TextArea
Hi, I used to have a DataGroup with a Renderer which had a bunch of TextFields, CheckBoxes, Dropdowns,... Worked fine, was using it with VerticalLayout with requestMaxRowCount =4. It had a button below to add an item or Delete button inside Renderer. All that worked fine on TitleWindow popup. I added a TextArea with heightInLines=2. Now it became a total disaster: I can not allow enough space to have 3-4 items. Tried maxHeight in DataGroup or Scroller or its parent FormItem. Tried to change requestedMaxRowCount in DataGroup VerticalLayout,... Nothing works. Any idea how to manage TextArea in DataGroup with Renderers? TIA, Oleg

Tooltip on GroupingCollection2
Hi,
Is there an easy way of showing tooltip on "folder" level
when you use ADG with GroupingCollection2.
if I use tooltip="{myGC.field1}" in ADG,
getting error 1119: access to possibly undefined property field1 through
reference with static
type GroupingCollection2.

Hi, We currently have a legacy Flex3 app with Cairngorm which we would like to bring into the Flex4 app with Parsley 2.4. Is it possible to put that Flex3 code as module into Flex4 project in FB 4.5.1? Is it possible to incorporate that Flex3 module as an item in Flex4 menu (using 3rd party component) ? Is it possible to get interaction between this Flex3 module and Flex4 items, like user selects a row of data on one side, and shows it in another view via XML data? Please advise. TIA, Oleg

Re: HostComponent is NULL?
All I get in error stack trace is 1 line (or 2 if it called not directly from MXML Spark Button definition, but from some method in that skin class): MySkinClass::Btn1_click: line xxx I am using Parsley 2.4 (if that is relevant). It is really strange: I wrote a lot of such view/viewSkin pairs and never seen that problem before. In that case I copied existing pair of them and copied into it some code from another pair with minor changes. Probably missed something all compiles and looks normal. have proper constructor in view... On Thu, Sep 11, 2014 at 3:54 PM, Alex Harui wrote: > Did you try to attach something?

Re: HostComponent is NULL?
I am calling it by clicking a button on fully drawn screen, so I would expect that hostComponent to be initialized by then. Are there any conditions to check or configuration I need to know about? Seems to work fine on many similar screens. Using Flex 4.5.1. And F3 does bring me to correct method.

HostComponent is NULL?
Hi, I am creating a View/ViewSkin pair, with view extending SkinnableContainer. As usual, often have to call hostComponent.method1(), but getting Error # 1009 Cannot access a property or method. I do define HostComponent properly in the skin. When I call that method1, hostComponent is NULL. Why? What I might be missing? TIA, Oleg

Expanding ADG to particular level
Hi, I have AdvancedDataGrid with multi level GroupingCollection2 which shows 1000s of rows. I am using displayItemsExpanded="true". Is there a way not to expand it not all the way up, but to the particular level of grouping, lets say to level 1 programmatically ? So in that case user will see 100s of 1st level groups (each having 5-10 rows inside). That makes a lot of sense and convenient to users. How can I do that? Using Flex 4.5.1 with Flex3 ADG. TIA, Oleg.

CreationComplete of ViewStack components
Hi, I have a popup (TitleWindow) which has ViewStack with a few NavigatorContent's which contain Form's with a bunch of components (TextInputs, DropDownLists, etc). User is editing some data, so when he selects ADG row and clicks Edit, that row data is displayed in that popup. I could easily populate data on the first NavigatorContent via onCreationComplete, but subsequent ones are showing me all DropDownList's as NULL. I tried to do myNavigationContent1.initialize() and myViewStack.initialize(), that didn't help. Any help is very appreciated. TIA, Oleg.

Filtering Hierarchical data in ADG
Hi, I have a true hierarchical data presented via HierarchicalData with input in XML in MX AdvancedDataGrid. Need to filter columns in ADG. None of existing filters (standard or some proprietary filters in my company) work. Any suggestions how to make it work? (haven't touched filters yet). Any help is very appreciated. TIA, Oleg.

ViewStack, states and validator
Hi, I have a popup where user enters data, currently implemented as TitleWindow with a ViewStack and several NavigationContent containers, having Forms with a bunch of components. When user clicks submit, it does validation and saves entered data to the database. I could have implemented it as a bunch of submits, but they have more or less same components and data (and process for example Add and Enter of same form). So should I create Add and Enter state? And a state for each NavigationComponent? Also there is still some difference between input components on different NavigationContent containers. That's why what is validated on one, is not accurate on the other. How should I handle that ? Please advise. Any code samples on that? TIA, Oleg. P.S. Using Flex 4.5.1

FormLayout not aligning
Hi, I have a Spark TitleWindow popup which has a Spark Form and a lot of FormItems, say 15 (mostly Label and DropDownList's). Labels range from 2-5cm. I do have FormLayout specified inside that Form (and VerticalLayout outside it, because there is a few Buttons at the bottom of the window, but outside the Form). All those Dropdown are set to the same width. However, on that popup these FormItems are not aligned, I mean those DropDownnLists are spread all over the form, not start on one level. Any idea how to fix it? -- Thank you in advance, Oleg. P.S. using Flex 4.5.1
DataGroup elements window adjustments
Hi, I have a Spark TitleWindow popup with Form, which among other widgets includes DataGroup (one of FormItem's) with custom ItemRenderer (where I put rows of data as per dataProvider contents - custom component). So user should Add or Remove a row of data on button click. Adding/Removing row works, but the popup size remains the same, so after adding more than 1 row it starting covering buttons underneath, then row goes out of popup. Is there a way to adjust popup size (make popup listen to number of rows) or at least put these DataGroup rows into some vertical scroller? (so far neither option worked for me). Using Flex 4.5.1 -- Thank you in advance, Oleg.
Working with '>', '<' in Web Service
Hi, I am using a Web service between Flex client and Java based server, some proprietary Web Service (which included REST/SOAP bridge). We have noticed when client puts '>' or '<' in their data [lets say in Description field he notes "if myValue is >0"], it creates exceptions in that Web Service. Is there a way to get around it? (still would like to see correct characters when data is retrieved from DB2) Less important: if user communicates using some foreign characters, they are not getting stored in DB2 database correctly. So when retrieved, they are usually getting converted in some 3 other characters. Not sure whether that happens because of Flex or something else. -- Thank you, Oleg.
Fwd: Rendering Spark Datagroup
Hi,
I am trying to create Spark custom component which represents a table row
which includes TextInputs, DropDownList and CheckBox,
that is to Add/Edit/Delete data (rows) to DB.
I am pretty new to component development,
looking at somebody else's code who did something similar (kind of repeater
where you can add/delete a row),
trying to at least bring their similar component on my form,
and so far failing to show it, even one row.
Granted, I don't have all data they have, so trying to fake it. Their have
structures within structures, within structures (for example, to show list
of values in DropDownList's).
And theire itemRenderer has 6 levels before it gets to standard Spark
component (I guess, trying to make code reusable, so break it in layers).
I would like to at least make it show up on my form and work simplest
possible way for now.
Have a lot of questions.
Some exerpts from their code:
[Bindable]
public var fieldColumnMaps:Array = new Array; // how is it passed to the
item renderer?
and why "new Array", not "new Array()". Is it legitimate?
[Bindable]
public var fieldColumnMapDS:Array = new Array; // includes fieldColumnMaps
among many other structures (e.g. dbFields array). passes to DataGroup
dataProvider.
// from that ColumnMapRenderer:
override public function set data(value:Object):void {
// Not called explicitly by anything. HOW does it work?
if (value is dbFields) {
dbFields = value as dbFields;
} else {
dbFields = null;
}
super.data = value;
}
Can anyone answer my questions throughout that code?
Any code samples?
So far I managed only to show that "Add Row" button on my form, and ONLY
if I do:
[Bindable]
public var fieldColumnMapDS:Array = [ {name:"anObject"} ]; // have to
initialize that array.
So does DataGroup require to have non-empty dataProvider to show anything?
Please advise!
TIA,
Oleg.
P.S.: this is alternative for me to doing similar development in FX
DataGrid (see another thread here about a week ago)

Re: Rendering components in MX DataGrid
Hi, Now I am able to render CheckBox and Button in MX DataGrid, but still can't use Spark DropDownList (or MX ComboBox) inside DataGrid, and it’s not working – DDL doesn’t show up and cannot populate it. Here is my scenario: User Selects a Version from another DropDownList outside DataGrid on the same form, we capture that Version, and call Stored Proc with that version via Web Service, It returns us data which we need to populate inside these DropDown’s. So far I cannot make these components to show inside DataGrid. In fact, as soon as I try to put them in the DataGrid (as itemRenderer with Component), It freezes that Version DropDownList, so no more Selection of Version is possible. I found a few examples on the net where all that is done with DropDownList in Spark DataGrid, but it doesn’t seem to work in Flex3 ComboBox (and I can’t give ID to that component inside DataGridColumn, so I can’t manipulate it from outside. Any idea how to do that with Flex3 DataGrid? (we use Flex3 MX and datagrids/ADGs throughout that app, so switching to Flex4 DGs/ADGs is not an option). Please help!

Adjusting layout on Button made invisible
Hi, I am using ApplicationControlBar with a bunch of buttons. Depending on some external conditions (app state), it should make some buttons invisible, change their labels, etc. When these buttons become invisible look like someone with missing teeth. :-( Is there a way to adjust other buttons positions so that it looks like one flow without any gaps ?

XMLListCollection as ADG DataProvider
Hi, I am trying to implement Object Model Explorer (something like Windows Explorer which would allow users to view & modify data in ORM kind of system consisting of 1000s of classes, so I need to dig into Classes which are 10s of levels deep (Class can contain other Classes or Attributes/primitives). In that case Path is not like a package, but true containment. Currently I am trying to implement a POC of such system with data in static XML. I tried to use Flex3 AdvancedDataGrid (with 1st column as a "Path", i.e. Hierarchical data - Tree kind of view). Tried to put data in XML, make XMLListCollection a dataProvider for ADG, was able to do it for simple cases, but when I do even simple thing like put a node as a data container: attrA attrB ... . that data is not showing up in ADG. Can you recommend a working code sample of XMLListCollection as dataProvider for ADG? (preferable with Hierarchical Data, not Grouping. although for starters regular data is OK too) -- Thank you, Oleg.
Building Class Explorer in Flex
Hi,
I am trying to build Class (Object Model) Explorer in Flex,
so it would show user Classes within Classes and allow View/Add/Edit/Delete
them.
This is not Flex classes, but kind of ORM system for user data.
So I receive user data as from DB with a row like:
Path (class4.class3.class2) - not like package, but true hierachical data.
Class (Class1 which consists of Attributes (primitives), say Strings, Ints,
etc)
Need to build a Tree from that and put it in the 1st ADG column.
I have 1000s of Classes, and it can go 10+ levels deep.
So any idea how to build a tree (HierarchicalData) out of that (true
hierarchical data, not grouping)?
Any code samples?

public var acClasses:Object = {
category:"root", children: [
new PathVO("class4", [
new PathVO("class3", [
new PathVO("class2", [
new ClassVO("Class1", { "Attr1", "Attr2", "Attr3"} )

Re: Search in ADG
Maurice, I did try adg.horizontalScrollPolicy="on" and adg.horizontalScrollPosition= - did not do a trick. And that adg.horizontalScrollPolicy="on" or "auto" only allowed me to scroll about 1/3 of columns, the rest is not visible.

Search in ADG
Hi, I have a Flex App where on several tabs (TabNavigator) I have MX AdvanceDataGrid's (wrapped in Spark Scroller's), which are dynamically populated (so I don't know in advance about 1/2 of Columns). Since the number of columns can be 200+, I am trying to implement a Search within Column Headers and data, one by one kind, so that when match is found, it highlights that cell or at least highlights that row and displays that column, brings it in user view. So far it shows that row, but I never was able to scroll to that column, so user can see it. I tried to use ADG's horizontalScrollPosition, verticalScrollPosition, validateNow with scrollToIndex,... When I try to set selectionMode="singleCell", that sometimes seem to freeze the app. Any advice or code snippet how to scroll to that matching Column? How to highlight the header and/or cell ? Can the problem be in that Scroller? Any help is very appreciated. -- Thank you in advance, Oleg.

Re: Dynamic validation in AS
OK, I tried the following:
private function validateRequiredField(field:TextInput):void {
var validator:StringValidator = new StringValidator();
validator.source = "{field}"; <<< Error: source attribute "{field}" can
not be of Type String [from mx.validators::Validator/set]
validator.property = "text";
validator.requiredFieldError = "This field is required";
validators.push(validator);
}
Any idea why I am getting that error above?
I am passing Spark's TextInput control there, not a String.
Calling it in "for" loop going through Dictionary of TextInput object,
where Key is column name.
How can I fix it?
TIA,
Oleg.

Building Spark DataGrid dynamically
Hi, I am building a screen with one Static DataGrid and one Dynamic (data comes through SOAP and I do not know the number of columns or their names in advance). I also get a list of column names in order from another SOAP call. That Dynamic DataGrid works (converting data from Vector of Objects to ArrayList of Columns). I still have a few problems: 1) I need to implement "Clear" of that Dynamic table. No matter what I tried: arrayColl=null; arrayColl.removeAll(); arrayColl = new ArrayCollection(); myDG.dataProvider=null; myDG.dataProvider=new ArrayCollection(); I am getting NULL reference exception coming from some system code:if (cell.visible)... where cell is null. How can I clear that dynamic DG ? full exception stack: TypeError: Error #1009: Cannot access a property or method of a null object reference. at spark.components.gridClasses::GridLayout/updateTypicalCellSizes() at spark.components.gridClasses::GridLayout/measure() at spark.components.supportClasses::GroupBase/measure() at mx.core::UIComponent/measureSizes() at mx.core::UIComponent/validateSize() at spark.components::Group/validateSize() at mx.managers::LayoutManager/validateSize() at mx.managers::LayoutManager/doPhasedInstantiation() at mx.managers::LayoutManager/doPhasedInstantiationCallback() 2) It seems that by default that Dynamic DG puts columns in alphabetical order, which is of course not what I need. Any way to disable that or fix somehow? 3) I need to show 2 DGs on the screen, and the second of them is Dynamic, and allow user to resize them vertically to be able to see more in static or dynamic DG. I put them in VDividedBox (and set height of both DG and container to 100%). It split the screen vertically 50:50, but still there is no draggable in between, so can't resize. Any help is very appreciated. TIA, Oleg.

Building Spark Datagrid dynamically
Hi,
I am getting data from the database via XML (SOAP Web Service),
and in that case I don't know number of columns or their names.
Need to display them in Spark DataGrid (and allow user to add, edit, delete
rows).
The complication I see here is that in that project there is Parsley +
proprietary corporate
Flex/Java soap framework, so I normally know a Value Object and get a
Vector of rows, converting it into a ResultSet to process.
in Parsley Command:
public function result(event:ResultEvent) {
var rs:Vector. = ServiceUtils.extractResultSet(event.result,
ValueObject);
...
}
But in that case there is no static Value Object.
Is there a way to create dynamic Value Objects?
Can you tell me how can I retrieve Columns (metadata) from XML (length and
Column Names) ?
Please help!
TIA,
--
Thank you,
Oleg.

Hi, I need to add the following to my Flex4 (4.6) Web App: 1) being able to select some cells from AdvancedDataGrid and copy it to Clipboard (to be able to paste to any file like Word, Excel, CSV or text file 2) being able to export the whole ADG context to Excel. Could you please suggest how to do it? (read lots of posts, but honestly none useful) Thank you in advance , Oleg.
Re: Dynamic DataGrid
It sounds interesting.
Not only we should not display columns without data by default,
but also user has an option to override that behavior ("force" some columns
from the list to appear even if they have no data).
so there is event for users to select/unselect some checkbox from list on
the screen.
