caching is something i thought about, but my question is how to utilize and use the request information during the post back, how does most of the extended JSF library that supports out of the box row selection works, do they cache either the record or thier keys !!!

Hi all,

if i need to build my own datatable selection mechanism, i mean i want to use the <h:dataTable> along with some mechanism to add the row selection cabapilities, how is the best way to do that, i tried adding a checkbox or radio as a column, but my problem is that when post back to the server, the datasource of that table will be invoked again which could get more or less records than the originally displayed ones and select the wrong record based on order.

so i think its better to get the datatable content from the request or so, any suggestions.

Thanks

Thanks for your reply, but im not sure you got my question right.

The case is that a select items is being populated using ajax , and that list is populated through the "get" method, but when the user selects a value from that list; JSF requires you to have that selected value on the back model, which may does not conatin it.

Hi,

I'm facing the famous issue of the value error on Dynamic populated Select Items on JSF, the issue is that JSF requires the model to have the selected value on the UI level while this is not valid since the values are not populated on the constructor (fixed) value on the backbean level, so is there a known fix (walk-around) for this behavior.

Thanks.

Me Nither happy to use this, but we have to apply this on a legacy application with minimum cost of time and code modification

i managed to share the session across the *.war files, using the extended functionality of IBM WebSphere, but my concern now is the way of handling the outcome navigation issue across these war files, so is there any suggestions!

Thanks in advance

Hi ,

Thanks for your reply , yes this happeneds randomly , and it hangs when it reaches "emf.createEntityManager" and nothing happeneds but sometimes it takes more than 2 min. to work but sometimes it fails , i can issue this problem run it from simple java application but iam useing IBM Websphere AS 6.1 , i checked the meta data and it looks fine to me , the worst thing it works sometime smoothly and from the first time , and another thing to add , the very same configuration and DB is working fine with Hibernate EntityManager , and about the lastest Toplink-essentials i tried multi versions ( on of them is the new 11g jar ) , but useless , any hints or ideas , Thanks
