<p class="MsoNormal">Hi all,<o:p></o:p></p>
<div>
<p class="MsoNormal">I have added my own custom text box field in the form 'Launch Instance' page. For that, I modified the following file:<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal"><b><i>/usr/lib/python2.7/dist-packages/horizon/dashboards/nova/instances/workflows.py</i></b><o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Added text box in the above script as follows:<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><br clear="all">
<o:p></o:p></p>
<div>
<p class="MsoNormal"><b><i>sample = forms.CharField(max_length=15, label=_("Sample"), required=False)</i></b><o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Now, I want to access the posted value of the above field. For that, I am using <b>context['sample']
</b>variable<b>. </b>When I clicked on the 'Launch' button, I am getting a Horizon alert error as the following:<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><b>There was an error submitting the form. Please try again.</b><o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Please suggest me to fix the issue.<o:p></o:p></p>
