Here is another enhancement for the project. It adds the attribute "preserveSortAndPage" to the table tag in both EL and standard versions. The idea is that (at least from usage on our own site) someone can sort a large list and get it exactly as they like it, then perhaps navigate away to something else, and would like to when they return see it the same way they left it (potentially, the data could change). However navigating back to it they likely wouldnt have the request parameters needed to sort it as it was, so when the preserveSortAndPage attribute is set to true, the current sort/page/sort order (and potentially previous sort/sort order) are all saved into session attributes named the same as they would as request parameters.
When the tag is executed and the preserveSortAndPage attribute is set to true it will first check the request parameters for the necessary information, and if it returns null from there it will fallback to session, then eventually to defaults. There is an inherent limitation to this, if someone had a list somewhere else on the site and it was using the same name variables for its list, and it also had the preserveSortAndPage attribute set the variables could clash, thats a limitation of the parameter encoder. I thought about tweaking the parameter encoder to also encode perhaps the current request.uri which would be unique to that list because it would be on a different page from another list, however we use struts and when I watched that value with the debugger it was just pointing to my base tiles layout.. (which was surprising to me).. so that wouldnt uniquely define the list either. So my conclusion is it should be a documented limitation for people that want to use this feature, they need to name their lists differently if they are going to use them across the site. Oh and I also fixed a bug that was in the TableTag.initParameters() method, it was attempting to load the previousSort from TableTagParameters.PARAMETER_SORT instead of TableTagParameters.PARAMETER_PREVIOUSSORT Enjoy.. many more enhancements/fixes to come I would imagine =) -David ------------------------------------------------------- This SF.Net email sponsored by Black Hat Briefings & Training.
