[Tapfx-users] Re: TapFX Filtering Table Example

[Louis M. <lou...@gm...>]

Cool, thank you, understand it all completely now...

I am actually looking at having a more complex filter table component, 
i.e. I want a input field for more than one column, and allow the user 
to filter on multiple columns. I.e. Have a input field for user name and 
then a drop down for the Department column, so you can search for users 
in a specific department. There must be a way to not have to code these 
input fields for each of my pages and be able to have it all in a single 
table component. We are going to have a couple of pages that we would 
like to have this kind of functionality on.

In any case, this might be the time for me to stop being lazy and to 
program my first complex Tapestry component...

Thanks for the quick reply!

The functionality you describe is really useful.
If you find a generic way to implement it,
I would be really glad if you could contribute the code
back to the community.

What I usually do, is treat the filter string as an intelligent input,
i.e. allow the user to input (in the same filter) more than one keywords 
(space separated),
the first for the firstname, the second for the lastname, the third for 
the portalcode, e.t.c.
Something like a search engine could provide.
I was also thinking of allowing filters such as
"name:lou lastname:meir", but in my case this was overkill.

Have fun,
Andreas Andreou

Re: [Tapfx-users] Re: TapFX Filtering Table Example

[Louis M. <lou...@gm...>]

I've got a lot more to learn about Tapestry components though, so this 
might take me a little while (if it is possible at all). Will definitely 
contribute the code if I get something like this going. I will do some 
research to see if it will be possible to create a component like this 
and let you know.

Thanks for your help!
Louis
