At this point, I need to open a black box. I really need to understand how the LiveGridView works vs the old GridView, as it will not work properly as is, and needs either configuring or sub classing to work properly. I never expected to have to do this, I figured that LiveGridView would just work for the most part.
Right now I'm backing off the original 5-10 SP estimate, as I have past that at this point. I'm unsure how many more points this will take as I'm unsure how long it will take to understand those black boxes I referred to above. The grid code is somewhat confusing and hard to follow with almost no documentation and extremely simple examples. Conversely its possible the forum posts may reveal some insight or some examples to look at which could solve this.
Seeing as we're already past the point to start testing, I doubt this will make it into 1.7. I did a quick look thru GWT's samples wondering if it may be easier to work with the vanilla google data tables, but they do not seem to have a live component and seem to be missing the ability to have a user selected page size. However, they are fast, and produce a smaller footprint than GXT tables.
For now I will continue and see if I can hit a quick solution, but I have extreme doubt. We probably want to talk about this tomorrow as a group.
Currently I'm pulling down GXT to learn, as the version I have is not the latest one we are using.
