It is said (by Knuth originally I think) that "premature optimisation is the root of all evil". I would suggest to stick with tiles for now, and when you have the application requirements nailed down good and tight and are in the pre-delivery optimization phase, take a look at it again, and if you find that you do need to squeeze out extra performance then use a custom tag, but if the performance is ok leave it using tiles as it will make future maintenaince easier...

We've been using tiles extensively in an app and it has been extremely effective - as one might expect for including "tiles" of information on a page and consolidating standard layout into templates - however I'm concerned that we might be going too far in its use... and using it where we might otherwise have used a custom tag: For a single img that is used extensively in an app that has mouseover/out/down behaviour, e.g. (in HTML - lots of code left out deliberately here): <img src="/images/navigation/right.gif" onmouseover="javascript:setImg(this,'/images/right_hot.gif')" onmousedown="javascript:setImg(this,'/images/right_hot_down.gif')" onmouseout="javascript:setImg(this,'/images/right.gif')"> This can be much simplified to including a "tile" of just this control: <tiles:insert template="/tiles-components/controls/imgactive.jsp"> <tiles:put imgName="/images/right" /> </tiles:insert> The alternative would be a custom tag, e.g: <sshtml:imgactive imgName="/images/navigation/right" /> Which is obviously much easier to include but so much less flexible - requiring editing tag handler java code to edit html - and all of the issues this entails - tiles allows us to edit the html in a nice easy jsp. This is much more effective for complete chunks of html and has saved huge amounts of time for large "composite controls" that we have everywhere. I feel it is neater but am concerned we are introducing too much processing for just producing the html for the control - does anyone else have a view on this ... any comments appreciated (even "Stupid Idea" if this is). (code for the template is included below).
