------------------------------------------
Still not tested, but I think it is a good idea; are there any objections around this?

> Pagination enhancement (paginate-target issue)
> ----------------------------------------------
>
> Key: OFBIZ-1118
> URL: https://issues.apache.org/jira/browse/OFBIZ-1118
> Project: OFBiz
> Issue Type: Improvement
> Affects Versions: SVN trunk
> Reporter: Wickersheimer Jeremy
> Priority: Minor
> Fix For: SVN trunk
>
>
> Currently Form pagination is using either the "target" attribute or the "paginate-target" attribute from the Form definition.
> After having hacked a few Forms and since i implemented another feature using this value ( column sorting ) i found out that
> - "target" value is seldom correct for pagination, it is very often used for update / delete links from the list
> - "paginate-target" is not really useful value because:
> --- if the form is used on multiple screen (therefore multiple URLs) it cannot be used and pagination should be disabled.
> --- if the form is used on one page only we have to repeat the target URL in the form which is taken from the Screen -> controller. Basically we are backtracking from the Form to the controller and coupling them.
> I don't have any example in mind were paginate-target would be different from the request URL and i often fixed missing paginate-target by copy pasting the part from the URL.
> So rather than running after the legion of forms that has a target but no paginate-target, those that have no paginate-target at all and those where pagination would be buggy because more than one form is on the same screen we can simply change the logic a bit.
> - we use "paginate-target" if explicitly set in the form
> - else we do not fall back to "target" bu to the request URL (from context parameters targetRequestUri)
> This is very simply done by patching the getPaginateTarget for the ModelForm. I won't attach a patch for now, just the code (simple anyway):
> public String getPaginateTarget(Map context) {
> String targ = this.paginateTarget.expandString(context);
> if (UtilValidate.isEmpty(targ)) {
> Map parameters = (Map) context.get("parameters");
> if(parameters != null && parameters.containsKey("targetRequestUri")) {
> targ = (String) parameters.get("targetRequestUri");
> }
> }
> return targ;
> }
> Is there anyone that thinks it is a bad idea .. or the reason why it wasn't done like this before ?
