Subject: A correction for the parameters:
X-Git-Tag: V_2.0.0_alfa1~48
X-Git-Url: http://git.salome-platform.org/gitweb/?a=commitdiff_plain;h=a26b3aee26fc2761728ea778939800b9b02e2a61;p=modules%2Fshaper.git

A correction for the parameters:

after entering the parameter name, when the value input gets the focus,
an error message is displayed (unnexpected EOF while parsing (<string>,
line 0) while the user didn't type yet anything. It's not fair.
The decision: do not set the editor value to the feature attribute by the control activation.
