v 12.0 Data source is not working with following error

[samannil]

XRP2:WARN:RestDataSource:isc_TestDS_0:DataSource specifies jsonPrefix, but not present in response returned from server. Processing response anyway. SC_Core.js:1223

[samannil]

This is SmartGWT v 12 and GWT 2.6.0

[samannil]

Here is the error in console

Read the error message, it explicitly tells you what you are doing wrong.

Before explicitly setting setJsonPrefix , setJsonSuffix , I checked the JsonSuffix and JsonPrefix , those are default value

isc_AppStartupDS_0.jsonPrefix
06:52:53.172 "<SCRIPT>//'"]]>>isc_JSONResponseStart>>"
06:53:04.576 isc_AppStartupDS_0.jsonSuffix
06:53:04.577 "//isc_JSONResponseEnd"

I specified the as follows in this method "protected void transformResponse(DSResponse response, DSRequest request, Object jsonData) "

this.setJsonPrefix("ABC"); this.setJsonSuffix("XYZ"); super.transformResponse(response, request, jsonData); Nothing change same error , what type of value do i need to set

Thanks for your support

Please read the docs for these properties. This is a security measure for JSON transports (as the docs explain). What you are doing makes no sense as a security measure, nor is there any reason why you would set these prefixes dynamically.

Thanks for your reply

I change the Struts2 server Prefix and Suffix

<param name="wrapPrefix"><![CDATA[<SCRIPT>//'"]]]]><![CDATA[>>isc_JSONResponseStart>>]]></param>
<param name="wrapSuffix"><![CDATA[//isc_JSONResponseEnd ]]></param>

here is a sample JSON output <SCRIPT>//'"]]>>isc_JSONResponseStart>>{"access":"Y", "firstName":"Car","infoMessage":"Car"}//isc_JSONResponseEnd

Here is the error message

Looks as if the response is probably malformed in some other way, but you've made basically no attempt to provide any information that would allow others to help you.

Let us know if you find any evidence of a framework issue, by providing a minimal, ready-to-run test case demonstrating the problem.

Again thanks for your answer , I have an app it is working properly with SmartGWT 4.0 , when I upgrade to V 12.0 it gave these errors , I just added the V 12.0 smartgwt.jar smartgwt-skins.jar and change some theams and index page stuff

[Isomorphic]

Yes, a botched upgrade could cause issues like this. As far as next steps, see previous post.

Hi,

I'd check the duplicate loads before (in gwt.xml and in main html?). Perhaps this is connected. Also, your detailed build version is missing.

Best regards

Thanks Blama

Now it is giving following error in V12


Thanks for helping this
