Sergio Lemos created CMIS-751:
---------------------------------
Summary: "Input String was not in a correct format" exception
while trying to get a document from Alfresco
Key: CMIS-751
URL: https://issues.apache.org/jira/browse/CMIS-751
Project: Chemistry
Issue Type: Bug
Components: dotcmis
Affects Versions: DotCMIS 0.6
Environment: Alfresco 4.2
Reporter: Sergio Lemos
Priority: Minor
Accessing Alfresco repository through CMIS using the .Net DotCMIS library, a
"Input String was not in a correct format" is thrown when it is tried to get a
document by its documentID.
This behavior happens on Alfresco 4.2, but not happens on 4.0.2.
Analysing the network traffic generated by the communication of the DotCMIS
library with the Alfresco server, it has been noted that the following data is
sent by Alfresco:
<cmis:propertyDecimalDefinition>
<cmis:id>sf_afi:vlr_total</cmis:id>
<cmis:localName>vlr_total</cmis:localName>
<cmis:localNamespace>sf_afi.model.procergs.rs.gov.br</cmis:localNamespace>
<cmis:displayName>Valor Total do Auto de Lanamento</cmis:displayName>
<cmis:queryName>sf_afi:vlr_total</cmis:queryName>
<cmis:description>Valor Total do Auto de Lanamento</cmis:description>
<cmis:propertyType>decimal</cmis:propertyType>
<cmis:cardinality>single</cmis:cardinality>
<cmis:updatability>readwrite</cmis:updatability>
<cmis:inherited>false</cmis:inherited>
<cmis:required>false</cmis:required>
<cmis:queryable>true</cmis:queryable>
<cmis:orderable>true</cmis:orderable>
<cmis:maxValue>1.7976931348623157E+308</cmis:maxValue>
<cmis:minValue>4.9E-324</cmis:minValue>
</cmis:propertyDecimalDefinition>
The DotCMIS library tries to convert the minValue and maxValue constraints from
its String representation to a Decimal data type. This is where the exception
happens, the value 1.7976931348623157E+308 cannot be converted to a Decimal by
the .Net Framework.
Analysing the same communication with Alfresco 4.0.2 server, it has been noted
that Alfresco 4.0.2 doesn't send the minValue and maxValue constraints to the
client, therefore, there is no errors.
The concerned property is defined as a d:double. We beleave that the problem
comes from the conversion from double to decimal.
