<br>
I have trouble getting a list of directory entries through the ParaviewWeb Visualizer.<br>
<br>
The ParaviewWeb Visualizer utilizes the ParaView source file: 'Web/Python2/paraview/web/<wbr>protocols.py’<br>
<br>
I have isolated the python code causing trouble and made a simple test:<br>
<br>
------------------------------<wbr>------------------------------<wbr>--<br>
from paraview import simple<br>
<br>
pxm = simple.servermanager.<wbr>ProxyManager()<br>
directory_proxy = pxm.NewProxy('misc', 'ListDirectory’)<br>
directory_proxy.List(path)<br>
file_list = directory_proxy.GetProperty('<wbr>FileList’)<br>
print "file_list.<wbr>GetNumberOfElements(): %s" % file_list.GetNumberOfElements(<wbr>)<br>
------------------------------<wbr>------------------------------<wbr>--<br>
<br>
‘file_list' remain empty no matter how many files located in ‘path’<br>
<br>
I have tracked the problem down to that ‘vtkSIDirectoryProxy::Pull'[1] is never called and therefore the 'FileList' and ‘DirectoryList’ properties of ‘vtkSMDirectoryProxy' is never updated.<br>
This can be fixed by modifying vtkSMDirectoryProxy::List[2] to:<br>
<br>
------------------------------<wbr>------------------------------<wbr>--<br>
bool vtkSMDirectoryProxy::List(<wbr>const char* dir)<br>
{<br>
  bool result = this->CallDirectoryMethod("<wbr>OpenDirectory", dir);<br>
  if (result)<br>
  {<br>
    this-><wbr>UpdatePropertyInformation(<wbr>this->GetProperty("<wbr>DirectoryList"));<br>
    this-><wbr>UpdatePropertyInformation(<wbr>this->GetProperty("FileList"))<wbr>;<br>
  }<br>
  return result;<br>
}<br>
------------------------------<wbr>------------------------------<wbr>--<br>
<br>
And changing ‘vtkSIDirectoryProxy::<wbr>ReadXMLProperty’[1]:<br>
------------------------------<wbr>------------------------------<wbr>--------------------<br>
if (strcmp(name.c_str(), "FileList") == 0 || strcmp(name.c_str(), "DirectoryList”))<br>
-><br>
if (strcmp(name.c_str(), "FileList") == 0 || strcmp(name.c_str(), "DirectoryList") == 0)<br>
------------------------------<wbr>------------------------------<wbr>--------------------<br>
<br>
I’m new to the ParaView code-base so I don’t know if this is the correct way to fix the above problem, any comments is appreciated.<br>
<br>
The above tests are performed on an Ubuntu 14.04 with kernel 3.13.0-112-generic #159-Ubuntu SMP and the official 5.3 source release (ParaView-v5.3.0.tar.gz) as well as the latest git checkout.<br>
<br>
Best Regards,<br>
