Issue 29

["Antony Miguel" <antony.miguel@scapatech.com>]

Hi,

 

Issue 29 describes the problem of static analysis given that the variable data function can have a variable as an argument.

 

A further resulting problem is that expressions in BPEL cannot be statically compiled.

 

e.g.

 

BPEL var1 = "/one/two"

 

XPATH = getVariableData("var2","part2",getVariableData("var1"))

 

the above XPATH expression *must* be parsed and resolved at runtime.

 

Does the technical committee see this as an issue or is static compilation of BPEL not seen as a requirement?

 

Are there plans to make the arguments to the BPEL extension functions non-variable, or plans to move away from using functions and instead use the $ prefix?  (I see that these possibilities were discussed but no post has been made to the issue for some time)

 

Removing the functions and using the $ prefix would fix the static compilation problem while still allowing variable arguments:

 

$myvar/one/two[$othervar/three]

 

cheers
