Right now we are using Tapestry 5.3.7 and upgrading is unlikely, so the async option is out of the reach, I think. I also do not want to open the save-file-dialog by default (the requirement from the client).
I will check the FileSaver as soon as I can. Is there a possibility that the zones could be used to refresh the button state (changing from disabled to enabled)? 2017-03-27 11:19 GMT+02:00 Christian Riedel <cr.ml...@googlemail.com>: > you could use t:async="true“ instead and return the pdf along with some > custom script that re-activates your button. > the binary of the pdf could be passed into FileSaver[0] to create the > save-file-dialog of the browser. while all this happens you could show a > progress indicator to the user. > > if you find this too complicated you could keep the traditional requests > but maybe open a popup that triggers the download. > > [0] https://github.com/eligrey/FileSaver.js > > > Am 27.03.2017 um 10:36 schrieb g kuczera <gkucz...@gmail.com>: > > > > Hi everybody, > > I have an actionLink, which action returns the pdf document from the > > server.
