TreeTable and DataTable in on view: selected items from checkboxcolumn are not set to backing bean


Hello,

I have a problem with a view, which combines a treetable on the left side and a datatable on the right side. First I select a node in tree and after this I select some rows in the datatable. After this I press the button under datatable to submit the selection from checkboxColumn. I have an attribut selected in the class for storing the selection, but no one is written on the field. That is a big problem, because without the treetable the selections works very fine.

I have add my application with source code for you. I removed the quipukit libs for smaller file size.


Best regards!

Joerg

Re: TreeTable and DataTable in on view: selected items from checkboxcolumn are not set to backing bean
Hello Joerg,

Unfortunately I wasn't able to figure out the problem by the source code that you have provided. The pages are too complex to investigate them without having a working version, and I'm not able to run the application because there are no compiled classes, and there are references to non-available files. Please simplify the page where the problem can be reproduced as much as possible to a minimum configuration where the problem still exists. This will help you resolve any possible problem in application logic if it is actually an application problem, and will let us see the specifics that causes a problem with QuipuKit component if there is such a problem. If you still won't be able to resolve the problem on the simplified application, please send us a war file with source code of the backing beans so that we can run the application and investigate the problem.

Here are also some considerations that might help you find the cause of the problem. Please double-check that the method to which the checkboxColumn is bound is indeed not invoked when the form is submitted. If it is not invoked the most likely problem is a failed validation or conversion somewhere on a page because the "update model values" phase is skipped in this case. This means that any other component would also skip saving its value into the backing bean, and you can check this assumption by placing and additional h:inputText on your page and see if its value is submitted. Please also ensure that there are no errors in server logs and no JavaScript errors in the browser.

Regards,
Dmitry

Re: TreeTable and DataTable in on view: selected items from checkboxcolumn are not set to backing bean

Hello Dmitry,

I have checked the validation of the page and i can not find any error of validation or conversion. I build a war file with source and compiled classes in WEB-INF folder.

I have checked the setter method of the backing bean with debugger and the method is never called. In quipukit version 1.2.2 the function works fine. I have found no errors or warnings in firefox error console.

Regards,

Joerg

Re: TreeTable and DataTable in on view: selected items from checkboxcolumn are not set to backing bean
Hello Joerg,

I have studied the working appliaction that you have provided, and it appeared that bindings do not work because the command link that initiates page submission has the immediate="true" attribute, which skips the "update model values" phase for all components, not just the DataTable. Removing this attribute or setting it to "false" makes check-box column bindings to work as expected. So this doesn't seem to be an issue specific to some version of QuipuKit.

Regards,
Dmitry

Re: TreeTable and DataTable in on view: selected items from checkboxcolumn are not set to backing bean

Hello Dmitry,

thanks for your help, but it doesn't works. I have remove the immediate="true" from the commandlink in the tree table, but the setter does not call from jsf in phase 4. I get a null pointer exception in my source code, because the value are null after pressing the button under the table. I have no idea anymore. We want to go live in end of september, but the bug will stop us. Can you send me the modified code that works? I will review this code and check the function.


Best regards,

Joerg

Re: TreeTable and DataTable in on view: selected items from checkboxcolumn are not set to backing bean
Joerg,

I just have changed the value of the commandLink's immediate attribute to "false" to make binding work. This was the only change in the war file that you have provided. The modified version of WebspaceFolders.xhtml is attached to this post. Please note that I can't ensure the correct work of your application logic on this page. I have just ensured that unlike the original war, the "update model values" phase is now executed when the TreeTable node is clicked, and check-box column binding is being written to. Please confirm that binding setter works for you as well in this same case.

Regards,
Dmitry

Re: TreeTable and DataTable in on view: selected items from checkboxcolumn are not set to backing bean

Thanks Dmitry,

You should ensure the correct work of my business logic.I have only a problem with quipukit. Please try this:

1. Click on a node in tree

2. select one or two items in datatable

3. Select an item in drop down box under the table

4. Press button with arrow on the side of drop down box

It doesn't works with quipukit 1.4.3 or 1.5, but it works with 1.2.2! That is my problem. The use case with immediate="true" works every time, but nobody will use it.


Regards,

Jöerg

Hello Dmitry,

we are changed our source code from checkBoxColumn to multiRowSelection with selection colum. And now everything works fine.

Thanks a lot!
