Layout Border component problem
Hi Guys, I just started to use T5 and lately I have hit a problem which I cannot resovle. I created a Border component which contains a navigation menu. I also created some kind of a sub-applications, let's call them MyMode1, MyMode2, MyMode3 etc and palced pagelinks to them in Border navigation. Then I implemented another border-like components MyMode1Border, MyMode2Border, MyMode3Border which are wrapped by Border and contains navigation specific to each Mode. Now, when a new user logs in the Border page, containing pagelinks to each Mode, is being displayed. Then the user chooses some Mode and starts doing some stuff. The problem is that when another user logs in and goes to the same Mode as the prevoius one he is given the same instance of the Mode so when he does some stuff on the page too he overrides what the other guy did. I added System.out.println to the non-argument constructors of each page and here is what I found out: When I restart the server and the first user comes in, clicks login button the following instantiations take place: com.kawecki.wapp.components.bor...@617584 [INFO] AppModule.TimingFilter Request time: 625 ms com.kawecki.wapp.components.mymode1bor...@2d09e0 com.kawecki.wapp.components.bor...@12297d7 com.kawecki.wapp.components.mymode2bor...@11d20d3 com.kawecki.wapp.components.bor...@1562c67 com.kawecki.wapp.components.MyMode3Border com.kawecki.wapp.components.bor...@149249e [INFO] AppModule.TimingFilter Request time: 594 ms Then, when the user clicks on one of the Mode pagelinks new objects are created just like above. But when new user logs in no new object are created and both of them uses the same instance of a MyMode1Border class. I read about page pooling, onPassivate, onActivate but my problem seems to work just opposite. So if anybody could let me know what I do wrong I would appreciate a lot. Hope I was clear enough Thanks in advance -- View this message in context: http://www.nabble.com/Layout-Border-component-problem-tp21004400p21004400.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
RE: Layout Border component problem
Hi Jonathan, thanks for your quick response. As you asked I uploaded classes I hit the problem in. Small description: One of my sub-application is Teacher (should be able to provide a word in foreign language and accept user's answer checks wheather it is correct) When user logs in, clicks teacher link is redirected to AvailabaleSets (which is wrapped by TeacherBorder). T5.zip file uploaded and it contains: - Border.java - Border.tml (pagelinks to all stuff provided by my app) - TeacherBorder.java - TeacherBorder.tml (contains all links to navigate my Teacher sub-application - i.e. TeacherMode - resposnible for 'asking question', registering results etc) - AvailableSets.java - AvailableSets.tml (displays available sets containg words) - TeacherModePage1.java - TeacherModePage1.tml (lets user to choose the word's set and decide about the questioning mode (mingled or the sequence of words had been added to the set) ) - TeacherModePage2.java - TeacherModePage2.tml (displays questions and lets to type in answers) TeacherModePage1.java contains the following line: private TeacherMode teacherMode = new TeacherMode(); I belived that when new page would be displayed (whe user clicks TeacherMode in TeacherBorder) a brand new TeacherMode instance would be returned but is not. And is not because all the classes are already instantiated and T5 gives them back to the user for efficiency. Please keep in mind this is just the beggining of the work, so not everything is like it should be from architectural point of view (i.e. @Persist will be replaced by onPassvate and onActivate). I just wanted to see how it works. If any more details are reqiured let me know.

Re: Layout Border component problem
Olle,
thanks a lot. I knew what was wrong but had no idea how to deal with that.
I am gonna check it out at home 'cause now I am at work.
thanks again

Re: Layout Border component problem
Hi Olle,
I finally got home and was able to check out your suggestion.
Works perfectly but I still have a small question:
I also used onActivate() to paste your code and it works as well.
So my question is: is it big difference between those methods and can both
be used interchangeably or this was only coincidence
Thanks again, I can finally continue on my work.
cheers

Thanks a lot Jonathan,

[T5 5.0.18] - How to 'turn on' dynamic validation
Hi Guys, I have a following piece of code in my *.tml file: As you can see I added two submit buttons and a validation to a textfield. The problem is that I would like to 'turn on' this validation only when user clicks Next button. Currently when the textfield is empty and Cancel button is clicked the T5 says that field cannot be empty. Probably this is possible on server side only but maybe I am wrong.
