Constructor arg of type String, pass in "" blank get an error

[borfnorton]

I have a constructor that takes a string. I am intentionally passing blank when I do a:

<constructor-arg value=""/>

Spring AS throws this error, rather than passing null or "" to my constructor

TypeError: Error #1009: Cannot access a property or method of a null object reference.

Hi,

this was indeed a bug when parsing empty strings as constructor arguments. It is fixed in SVN.

Thanks for mentioning.

Hi Christophe,

There is a simialar issue with intentionally passing a blank value to a property.

<object class="Object">
<property name="label" value="123"/>
<property name="data" value=""/>
</object>

Spring AS throws this error, rather than passing null or "" to the object.

Thanks for your help,

Hi Nick,

you can use the <null/> element for that. But perhaps the the parser should be smart enough to intercept this.

Can you please file a bug in the Jira?

regards,
Christophe

Hi Christophe,

I logged a bug for the parser to handle the error being thrown.

Here is the JIRA bug: http://jira.springframework.org/brow...IONSCRIPTAS-49

Thanks for your prompt response,

Is the fix for this coming out in 0.9? and when will that be released?
