In the server manager XML I used hints to make sure that the tables are not automatically opened at once (<View type="None" port="..." />). This works nicely so far.</div><div><br></div><div>Now the filter is producing a time series, step by step modifying the "unstructured grid", and some data written to the tables per period.</div><div><br></div><div>What I see now is that the "unstructured grid" is doing what I expect: I can go up and down along the time axis and it always shows the proper graphical output. I can also capture the data in a spreadsheet, and this is also properly updated.</div><div><br></div><div>Not so the additional tables! In this case they are updated ONCE and never again, so I can have different scenarios:</div><div><br></div><div>- I add the filter and press apply. This would bring me to step 0 - with empty tables. If I open now a spreadsheet view and look at any of them this correct. But if I now press "play" and go from step to step, only the "unstructured grid" gets updated, not the spreadsheet view.</div><div><br></div><div>- I can also add the filter, press apply and immediately also "play". With that I am at the last step, and opening a spreadsheet view for the tables gives me the full tables - again correct. But again: if I go back in time, the tables stay as they were initially (i.e. full).</div><div><br></div><div>Now I prepared a demo case for this. It has just two tables, one being shown immediately and the second only "on demand". Indeed I could almost reproduce the behaviour: the first table does what is expected, but the second not. Only difference with my full case: the second table NEVER shows anything, no matter if I press the "play" button earlier or later!</div><div><br></div><div>It is interesting to note that the "Information" panel shows the tables correctly, like: X rows, Y columns - even if the spreadsheet view is completely empty. Or showing much more!</div><div><br></div><div>My question from the beginning is now: Is there something that I would have to do to trigger a spreadsheet view update or is this a bug that needs to be fixed? (Actually I hope for the first because then I can quickly apply the fix in my own software and I am fine!...)</div><div><br></div><div>I am attaching a package with source code (h, cxx and xml files) plus a screenshot that illustrates the case where the second table shows some content only in the properties panel (left), but not in the spreadsheet view (right).</div><div><br></div><div>With many thanks for any helpful hints - and kind regards,</div><div>Cornelis</div></div><br>______________________________<wbr>_________________<br>
