Hi everyone,

Just for the records I found a more simple solution for this without the
javascript stuff:
I also had problems that the pager did not update or jump to the new
row/page when
clicked on a page and all this packed in a hidden div.


your tml:

<div id="${hiddenDIVID}">
              
                    <t:gridpager currentPage="currPage"
rowsPerPage="literal:50" source="phenotypes"/>
                    <div t:id="theGrid" />
</div>

your java code (only relevant part):

@Component(parameters = {"source=phenotypes", "row=loopPhenotype",
"pagerPosition=literal:none"})
    private Grid theGrid;

@Property
    @Persist
    private Integer currPage;


@SetupRender
    public void setupRender() throws Exception{
//init for the first time
        if(currPage==null) {
            currPage=1;
        }
        theGrid.setCurrentPage(currPage);
//now every time a page reload occurs we point the grid to the page
theGrid.setCurrentPage(currPage);
}
