I would expect the following code to change the filter the list datasource of
the second combo box using the value of the first. I do not get errors and
the temporary filter returns the expected string. However, the second combo
box does not change.
#get current value of combobox: function returns viewcolumn
filtervalue=hk_thisform.get_pyvisible("cbosubject").value()
#so we must find the associated listcolumn value by finding the corresponding
value in the same row
rownum=hk_thisform.get_pyvisible("cbosubject").viewcolumn().find(0,1000,filtervalue)
hk_thisform.get_pyvisible("cbosubject").listdatasource().goto_row(rownum)
filtervalue=hk_thisform.get_pyvisible("cbosubject").listcolumn().asstring()
filterstring="subjectid = " + filtervalue
cboCourse=hk_thisform.get_pyvisible("cboCourse")
cboCourselist=cboCourse.listdatasource()
cboCourselist.disable()
cboCourselist.set_temporaryfilter(filterstring)
cboCourselist.set_use_temporaryfilter(True)
#cboCourselist.enable()
hk_this.show_warningmessage(cboCourselist.temporaryfilter())
