I am trying to create a datagrid in FLEX. The trouble is that I want it to be 100% dynamic - i.e. columns & data.
Basically I need to populate the datagrid via a result set from a database query, this data will be gathered via a standard java spring jdbc dao layer. The query is as generic as 'select * from tablename', so the result set can change from query to query.
My plan is to convert this result set into some form of java object, my initial thought is a Map of some kind that will contain the column name and values for a row.
The bit Im struggling with is that I need to convert this result set into a ActionScript object (via graniteds) that I can then use to populate a datatable.
I have seen lots of examples on how to dynamically add columns to the datagrid, and tie in the data via the datafield object - but Im stuck as to how I do this if I dont know how many columns I will have or what the column names will be.
I have a datagrid which displays details for a product. For a particular product i need to display its Id current status(Available/ Not) and which category it belongs to. The category part is a bit different from what it seems to be like. Product A can belong to Category A, B and C while product B belongs A ,c and D and so on. Structure of this table would be something like The category columns are retrieved from database and passed as parameter to construct the columns dynamically in Datagrid. I have defined the following Datastructure on UI to handle this.
Product{ var productId:String; var productName:String; var status:String; var categoryList:ArrayCollection; }
I am not sure if this will be able to solve my problem. I think I will need to have a Map containing category Names and if it is applicable for that product.
I'm trying to create a dynamic datagrid in Flex. The data is coming back fine and I can add the column headings. I need to do it this way as the column names are dynamic and coming from a mysql database.he values from re.result.resultSet.results[j].notes into the data fields?
I am newer with flex technology.I am creating a chart using ant file & .mxml in eclipse my 'ant' file executes properly but it gives following error when i opens a .swf file which is created auomatically:
Flex Error #1002: Flash Player 9.0.115 and above is required to support signed RSLs. Problem occurred when trying to load the RSL
with the platform j2ee,data of datagrid is from java dao(from the database),so which way is better,to export the data of datagrid to Excel with java dao or flex?
i used array collection sort method like below . but still sorting wrongly . Any other solution for sort date using flex3
public function SortingDate(ArrColl : ArrayCollection, field : String) : void{ var sortA:Sort = new Sort(); sortA.fields=[new SortField(field,false,true,null)];[code]...........
how to structure the comms of a blazeds/flex game. What I'm trying to achieve is to have x no. of games occuring on the server each of which will contain 2 to 6 players. i think this will involve segmenting a feed, by creating a subtopic. eg game A gets filled with Player A + Player B, a dynamic destination gets created on the server side, and the new destination id gets returned to the clients. Not sure if I have that correct - to give some further background - the main server side code for a 2 player setup is here
Connecting multiple flex clients to a single java class
I created a screen(calculator) with bunch of buttons,i can handle button event with one handler.But i want to know that can we do a one handler for all buttons......likein java we can perform the task of perticular button by like this
I receive from the httpservice with a certain frequency a string like this:1#3#234525234whererow#column#valueI want to display into datagrid the above string at real time; at the moment my code displays the whole string, composed by many strings like the one above.How can i solve the problem?I have the following code
There are several ArrayCollections and DataGrid in my application. Number of ArrayCollections determined by the input data. How to create own dataprovider for each DataGrid column?
Back again with another Flex question. I have an XML structure like...
[Code]...
Now I got his displaying on my grid by saying dataProvider=XMLListCollection... What I want to do is on selection of a row, check if it has "Address" tag, if it has display the other grid, else hide the grid.
I have a question about the Spark DataGrid and how it works in terms of garbage collection. What I'm finding is that if I dynamically add and remove columns from the DataGrid at runtime, the GridColumns and ItemRenderers never get freed from memory.
For instance, if I have a list with 10 items and I create 10 columns, there will be 100 ItemRenderers and 10 GridColumns. If I remove all of the columns, they are still there.
I'm using FlashBuilder 4 and trying to create a dropdownlist that populates a datagrid. The functionality is fine but my data is being chopped up too much. Currently every since "nepName" tag in my XML file is showing up in my dropdownlist (which makes for many duplicates of the same names) and only shows the data associated with that nepName tag. I want each nepName (by name ex. Barnegat Bay National Estuary Program) to display only once in my dropdownlist and populate my datadgrid with ALL the data in the XML file that is associated with that name
I tried with flex and java in the backend. In this, I am able to upload files till 100 MB using remote object (blazeDs) where we will read the file as byte array and send it to the java method. If the file size exceeds after that, then I get the run time error in IE.
I could play MIDI file where "filename" is a String type with "asd.mid" value. However, I tried to sent AIR's nativeprocess command to Java, it shown "could not read" error.
I am using Flex 3 and make a call through a RemoteObject to a Java 1.6 method and exposed with BlazeDS and Spring 2.5.5 Integration over a SecureAMFChannel. The ActionScript is as follows (this code is an example of the real thing which is on a separate dev network);
I'm building a Facebook multiplayer game where the client side is in FLEX and the server side is in Java and I wanted to know if there is a guide on how to build the server clients managing system. When I say server clients managing system, I mean a server which many clients will connect to and will be able to choose between tables to join and play or to create their own table, same way as in texas holdem poker.
i am working on a flex+java combined project.My IDE and computer configuration is as follows:
[Code]...
When i make a small change in Flex code (eg, reposition of a button...anything), and run the project on server, it does make any change on output. Actually it depends on my luck... because it makes change in output randomly.what is is happening? tried rebuild, republish, clean , restart server, restarting the IDE, restarting the computer all available feature i could think. Also, i created a simple flex project on IDE and compiled it..... everything is compiled and displayed on output.
Right away i just try to explain my problem: Using BlazeDS i got the following Javaclasses:
[Code]...
Then i got a Flex service class calling BlazeDS and executing the getCategories java method. Since Flash dosn't seem to understand typed arrays, the result from that method which i get back in flex is a simple array of untyped objects (the mapping dosn't seem to work here, even tought the class category exists in flex and has the same properties). thats the first thing. but however, i'm converting the untyped objects manually into objects of the category.as class. the second thing is that categories have child-categories within the java object, which are also ArrayLists of the type category.java. the problem about that: my result event object only contains the first level of categories, looking into them the children are allways null. i dunno why they are empty, since they ARE part of the java object category.
and the third thing (the strangest by fast), you maybe noticed i named the properties of the category.java class strange, like idCat and nameTest instead of simply id and name. why that? because the property names of my flex result objects dont seem to change when i change the java objects properties names (result object properties are named "id" and "name" but the java class object properties are named "idCAT" and "nameTEST"). that it REALLY strange, since if i set the properties, like you see at nameTEST = "TESTNAME" it IS recogniced by flex, only the proertyNAMES dont seem to be recognized at all.
I'm coding a web app in flex blazeds and Java. I installed the Eclipse plugins for using WTP mixed project. I'm using flex's server that uses an emulate of tomcat when i ran my flex service the web app got the datas, everythings is ok. the problem is when i copy the project with all files generated by flex in my tomcat or the blazeds's tomcat, it doesn't work, this is becasue i want to implement my app on a server the error is:[code] i don't know why tomcat doesn't find the class of flex.messaging.endpoints.AMFEndpoint that is used for my-amf 'URL...'. all works well in the emulated server that flex has.
Assume I have the following java class public class Square {
[Code]...
Inside an actionscript class, using RemoteObject, I invoke the java method SquareDAO.findById(Long id) an I get an Object with the following: But I don't get the area. How can I invoke the method getArea() ?
I've knocked together a Java/BlazeDS server which creates a generic GridBean object. This GridBean contains:[code]I then created a Flex app that uses a RemoteObjectServiceWrapper to call my java server, grab the GridBean, create some DataGrid columns from the columnDefs and then set the dataProvider as the list of objects. Ok so far, everything renders.Now, what I'd really like to do is: set up some kind of event handler on the flex side so that if my item/object is edited in the datagrid, I fire a message off to java saying 'edited this field on this item'. The end goal is to have a nice generic way to render any list of objects from Java in a flex datagrid.
