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?

[666shooter]

As far as I can see this issue has been resolved (at least that's the status in JIRA as you can see).
It was fixed before the v0.8 release so it should work in the current version.
If you still have problems with it, then please create a new issue in JIRA with a description of how to reproduce the problem.

You can add issues in JIRA here:
http://jira.springframework.org/brow...ACTIONSCRIPTAS

cheers,

Roland
