NumberFormatException - handle text in number metadata? ...

[csiege]

I have a custom content model type defined with a property of type int.  When a user enters some text into that field and clicks ok, the webclient gives a VERY nasty error message and the log file records the NumberFormatException error.

The biggest problem is that the error message doesn't give the user any indication that they simple entered a text value into what was expected to be a number.

Is there a mechanism for handling this?

As always, thanks for the help!

What version are you using?

We added support for constraints in 1.3 which the property sheet handles. You could use the NumericRange constraint on the property or write your own custom constraint.

However, I agree, this is a bug, the property sheet should deal with that scenario in a graceful manner.

Do you have an example of how to use NumericRange?

thanks!

ok, I got this working… BUT

Is there something I am missing here?  Is there some hidden documentation around to explain this stuff…  the only way I could find out how to get this working was going through the source code…  and even with that I feel a little lucky…

I think this is an undocumented feature!!

By the way, I raised an issue regarding your original problem, if you want to track its progress: http://www.alfresco.org/jira/browse/AWC-777

To get an example out here on the forum here is what I found 🙂

     <property name="myLNB:labNotebookNum">
               <title>LNB Number (number only)</title>
               <type>d:int</type>
               <constraints>
                              <constraint type="MINMAX">
                                    <parameter name="minValue"><value>5</value></parameter>
                                    <parameter name="maxValue"><value>10</value></parameter>
                             </constraint>
              </constraints>
       </property>



also an example I found in JIRA that looked useful…

<constraints>
      <constraint name="cm:myconstraint">
         <min>0</min>
         <max>255</max>
         <regex>[a-z]*</regex>
         <length>100</length>
         <list>
            <value>0</value>
            <value>1</value>
            <value>2</value>
         </list>
      </constraint>
   </constraints>
   
   <types>
   
      <type name="cm:cmobject">
         <title>Object</title>
         <parent>sys:base</parent>
         <properties>
            <property name="cm:name">
               <title>Name</title>
               <type>d:text</type>
               <mandatory>true</mandatory>
               <constraints>
                  <constraint ref="cm:myconstraint" />
                  <constraint>
                     <regex>[A-Z]*</regex>
                  </constraint>
               </constraints>
            </property>
         </properties>
         <mandatory-aspects>
            <aspect>cm:auditable</aspect>
         </mandatory-aspects>
      </type>
