[Laszlo-dev] FileUtils.java log

[keiji Ono]

I have been continuing to solve this issue.
And i look at the point of the suspicious, but i could not know it clearly.
At the point is in SOAPDataEncoder.java.
The 'issue' code is in the method of _traverseDOM().

SOAPDataEncoder.java _traverseDOM()

iter = el.getChildElements();
while(iter.hasNext()){
Object o = iter.next(); <---- 1
if( Text.class.isInstance(o) ){
characters(((Text)o).getValue() ); <---- 2
}else{
.
.
}
}

At the point of 1, when the Object o contained a string
"<sometag><![CDATA[ Text Strings]]></sometag>",
.getValue() at the point of 2 got the string "Text Strings" and
set it to the method of characters(). The characters()
push it to client through FlashBuffer class.
The issue of it is the blank of the start strings has been rejected by 
getValue().

I do not know whether this is the specification of getValue() of 
org.apache.xml.message.Text class.
Is not there the person knowing a lot about this?
