Is there any open-source project which implements EPUB reader in Flex? Thanks for any info Zdenek M
[flexcoders] URLMonitor timeout
I am trying to detect the online/offline status of my Air 1.5 application using URLMonitor. Unfortunately when the status is offline, the first StatusEvent after monitor.start() comes after very long timeout (20s?). Is there any method how to make this timeout shorter? Zdenek M
[flexcoders] LCDS, Hibernate and offline synchronisation in Air
I am trying to make the database application in Air, which should work
also offline. But I have a problem with associations.
I have two databases: Partner and Contact. In Contact there is a
ManyToOne association to Partner, based on the join table:
@ManyToOne(targetEntity=Partner.class, cascade={CascadeType.ALL})
@JoinTable(name=partner_contact,
joincolum...@joincolumn(name=fk_contact,
referencedColumnName=contact_id),
inversejoincolum...@joincolumn(name=fk_partner,
referencedColumnName=partner_id))
private Partner partner;
The problem is that when I create a new partner offline, then add a new
contact referencing this new partner, everything is OK when I am
offline, but after getting online and commiting offline changes, the new
partner is created two times.
Does anybody know the fix for this?
Thanks in advance

[flexcoders] LCDS 2.6 + Hibernate: problem deleting items
I have got big problems deleting items from my managed collections: When I delete item through ds.deleteItem and then call the ds.commit, after return from the commit operation my item is back in the ArrayCollection. The second time this item is deleted properly. When I delete item through ac.removeItemAt the item is again restored by commit, but this time it is impossible to delete this item by the second call. When I delete item from the collection and add another item into the same collection, the commit fails and the server returns error The item was not in the cache... Does anyone know how to fix these problems? My items have to be improperly cached somewhere... TIA Zdenek
[flexcoders] LCDS: data management and limited access
I am trying to limit access to my flex application which works with LCDS 2.6 data management endpoints configured to use only the rtmp channel. I would like to limit access to my application from just certain ip addresses - I want to list these ip addresses in whitelist property of my server, but with this setting I am still able to connect to my application from ip addresses which are not in this whitelist. Even if I put my ip address into blacklist in services-config.xml file, I am still able to connect and see the data from my endpoints. I am a little confused why this feature does not work? Zdenek M
[flexcoders] LCDS: how to fetch the items from lazy collection
I have an ArrayCollection which is filled from the LCDS/Hibernate destination with lazy=true. For display it is OK, but for export I need to go through all items to send them to output. Is there any way how to force fetch all items from the server? BTW the sample in LCDS ES 2.6 Developer Guide on page 242-243 is wrong - you will get the ipe exception on line with ipe.addResponder in catch clause. Zdenek M
[flexcoders] LCDS data management - original data on the client
I am using LCDS data management with Hibernate assembler. My dataservice is configured with autoSyncEnabled set to false and in my Flex application it is possible to make various changes to data in ArrayCollection resulting from fill operation. Then before commiting the dataservice I would like to inspect these changes. Are the old values of data (which were originally read by fill operation) accessible anywhere on the client? Zdenek M
[flexcoders] LCDS 2.6 - problem in samples
I have just downloaded LCDS 2.6, installed it on Tomcat 6.0.16 (not using the integrated Tomcat). Then I installed JOTM 2.0.10 into Tomcat and tried to run the CRM sample. Unfortunately when I added new item (company or employee), it crashed every time with strange java exception. After some digging on web I found that this is caused by conflicting library commons-logging.jar in lcds-samples/WEB-INF/lib folder - when I removed this jar file, the CRM sample started to work. I wonder if this problem is also in the integrated Tomcat.
[flexcoders] LCDS/Hibernate + Tomcat - socket write error
I have a problem with my webapp: after some time it returns the SocketException: socket write error, then the Tomcat has to be restarted to get it run again. I have found the blog about similar problem on JBoss (http://viconflex.blogspot.com/2006/11/how-to-keep-db-connections-alive-in.html). Does anyone have a solution for this problem on Tomcat? Thanks in advance
[flexcoders] HorizontaList - variable column width
Is it possible to have variable column width in HorizontaList (similar to variableRowHeight for List)? Zdenek M
[flexcoders] LCDS and Hibernate - how to setup bidirectional relationship
I have got bi-directional association defined in LCDS and Hibernate - one Parent has ArrayCollection of many Child objects, in Child I have the pointer to its Parent. All works correctly, but when I try to delete one of the child objects (either by parent.childs.removeItemAt() or directly through dsChild.deleteItem()), my parent object just disappears - it is deleted as well. I can fix this by making the relationship one-directional (then it works), but I think there has to be some setting either in LCDS or in Hibernate to prevent this. Thanks in advance for some advice Zdenek M
[flexcoders] LCDS and Hibernate - how to write equals() and hash()
I have seen some discussions on the web about not using database generated id in equals() and hash() functions for data objects (in java DTO model) as it changes during save operation. But in the open source samples there are either these functions based on id (http://weblogs.macromedia.com/pent/archives/2007/10/flex_and_hibern.html) or these functions are omitted (http://blogs.adobe.com/mtg/2006/08/my_first_hibernate_enabled_fle.html and http://fleksray.org/flex_datamanagement_service_hibernate_en.html). IMHO these samples will not work correctly with more complex object trees. Can someone give me the advice how to deal with this issue: is it better to compute hash from all properties (columns) of object or is it better to add special uid column into tables (and save it inot database)? The object retrieved from LCDS into Flex has the uid property - is it possible to use this property in equals() and hash() functions (in Java)? Thanks in advance for answers and opinions. Zdenek M
[flexcoders] Flex Builder 3 plugin problems opening perspective
I had some problems with my installation of Flex Builder 3 plugin in Eclipse 3.3.2 in Windows Vista (design view stopped working) so I tried to reinstall Flex Builder. But after reinstallation I am not able to open the Flex Development Perspective - the alert says Problems opening perspective com.adobe.flexbuilder.editors.mxml.ui.perspectives.development. Does anybody know how to fix it? Zdenek M
[flexcoders] Srollbar for list of images
I have got the simple HorizontalList with Image as an itemRenderer. When the dataProvider has more items than columnCount, the scrollbar is automatically added to the bottom of the list. But this scrollbar obscures part of each image. As I need to have my images vertically centered (they have got various aspect ratio), they are centered in the original vertical space, not in the space left after scrollbar is added (there is space between top of the list and the image, but the lower part of the image can be obscured by the scrollbar). Is there any simple solution how to add the scrollbar outside of the items?
[flexcoders] Platform independent paths in AIR
Is it possible to get platform independent path for file or folder in Adobe AIR? If I want to use the same Air application on Mac and Win, how can I translate the file paths between platforms? (The native path on Win does not include the server name, only the mapping on letter.)
[flexcoders] LCDS one-to-many managed association
I am struggling with very simple sample of one to many managed association using mySQL database and custom Java assembler extended from AbstractAssembler. I have got two destinations, parent and child. In parent destination there is an ArrayCollection property which is associated with child destination. I fill this ArrayCollection in my parent assembler. Everything is fine, the data are correctly transferred from the database to the client and when I add item into my child ArrayCollection, the function create in my child Assembler is called. But when I delete item from the child ArrayCollection, my child Assembler is not called, only the update function in parent assembler is called. Does anyone have a clue what should I do to fix this? Best Regards Zdenek M
[flexcoders] LCDS one-to-many managed associations
Hi, I am trying to comprehend how to implement the one-to-many managed associations in LiveCycle Data Services. Unfortunately there is no complete sample available. I have got the Company and Employee tables in database and there is an id_company foreign key in the Emploee records. I naively expected, that when I set the one-to-many association (in destination Company) and make the fill operation on ArrayCollection of companies, the LCDS will automatically call the fill method for emploees property in each company. But obviously this is not the case - I will have to fill this child ArrayCollections (or at least the IDs for lazy associations) in my custom Java assembler for the parent (Company) destination (using SQL query to Emploee table). But I am not sure how to pass this child List from Java to ArrayCollection in AS. Can someone explain this to me? And are there any other places in Company Java assembler where I have to work with Emploee table or is then the creating, updating, and deleting of employee accomplished by simply creating, updating, and deleting items in emploees ArrayCollection in AS? Thanxs Zdenek M
