length of Title(synopsis) field

Can i increase the length of Title(synopsis) field from 80 to 200?

You can create a custom field of type "Short text" for title:

At Administration > Customize > Custom fields...
1. Set a default value for the actual system field called Synopsis because it is a required field and should have a value even if it is removed from the issue edit forms. Eventually if it is the case you can rename the label (not the name) in to avoid having two fields with the same label "Title".
2. Create a new custom field of type "Short text" called Title.
At Administration > Customize > Custom forms > Form configuration...
3. Remove the original Synopsis field and put the new Title field in the differnt issue editing forms (screens).

The problem is that in some places the Synopsis field appears hardcoded, for example in some JasperReports. You should change than the report templates with the ReportStudio (http://www.trackplus.com/reportstudio.html)

Thanks..

I've defined a custom field with a length of 200. How do I set the length of the Input Box? I've attached a screenshot.

Edit the following template <TomcatPath>\webapps\track\WEB-INF\classes\plugins\fieldType\templates\textBox.ftl and add the size attribute to the textField:

<#assign s=JspTaglibs["/WEB-INF/tlds/struts2/struts-tags.tld"]>
<@s.if test="invisible">

</@s.if>
<@s.else>
<@s.textfield name="${nameMapping}" theme="simple" size="60"
disabled="readonly" title="${tooltip}"/>
</@s.else>

A Tomcat restart is probably needed.
The disadvantage of this solution is that this template refers to all text boxes. It means the field called "Build" and any further custom text box will have the same length. But if you do not use the Build field (remove it from the forms) it could be a solution for you.
