UNABLE TO READ COMPOUND TYPE MODULE BEANS IN FTL

[raja harivansh]

Hi People,

SCENARIO: I have a compound type and a document type. 

Now this compound type can be added either as a content block or added as a compound type directly in the document type.

When using it as a content block, the content authored in it is displayed correctly. 

However, when I use it as a compound type(directly added in the document type), i cannot access its module in the ftl. 

NOTE: HOWEVER, I can read the module and its values in the component class using the getter method. I just CANT ACCESS the same value in the ftl !!

Here's the calling ftl-

<#import "../../common/components/iframe-module-macro.ftl" as iframeModuleMacro/>

<div class="imc-content--full-width-block">

                <#if  pageModelMap.modelMapData.module.iFrameModule?? && pageModelMap.modelMapData.module.iFrameModule?has_content>

                <@iframeModuleMacro.displayIframeModule iFrameModule=pageModelMap.modelMapData.module.iFrameModule/>

                </#if>

                </div>

Here's the macro- 

<#include "../imports.ftl">

<#macro displayIframeModule iFrameModule>

<#if iFrameModule??> 

<!-- Vertical Rhythm -->

<#assign marginBottom="xlarge" > <#--[none, micro, xxsmall, xsmall, small, mediumsmall, medium, large, xlarge, xxlarge, xxxlarge, jumbo, collosal]-->

<#if marginBottom != "none" >

<#assign verticalRhythmClass="imc-vr--${marginBottom}">

<#else>

<#assign verticalRhythmClass="">

</#if>

<#assign iframePath = iFrameModule.sourceUrl/>

<#assign dataXpath = "IFrame Integration" > <!-- This will be updated once Page metadata component is set and picked from those values-->

<section class="imc-section imc-content imc-section--padded imc-content--border ${verticalRhythmClass}" data-xpath="${dataXpath}" >

<iframe src="${iframePath}" height="615px"></iframe>

</section>

</#if>

</#macro>

Here's the module ftl- 

<#import "../../common/components/iframe-module-macro.ftl" as iFrameMacro/>

<@iFrameMacro.displayIframeModule iFrameModule=moduleBean.modelMapData.module />

PS: I can read all the other modules in the document , except this one

Any idea why this could happen?? I've been tearing my hair over this for days now and its been in vain.

Hi,

Any luck yet? It looks alright indeed.

Perhaps it's better when you first do an #assign, then call the macro with that variable? Else debug the getters? A full rebuild?

HTH

My bet is, the exception occurred in your "module ftl" because you don't have any checking (?? and ?has_content), unlike your "calling ftl".

Can you add that checking here as well and see what happens and why?

Regards,

Woonsan

@Woonsan

No that didnt work either. :( 

@Jeroen

Apologies.. I didnt quite get that :P .Could you please show what you meant?

[raja harivansh]

Hi All,

I pin pointed the error. 

I had been using the pageModelMap.modelMapData.module.IFrameModule with a smaill "i" instead of capital "I". 

                <@iframeModuleMacro.displayIframeModule iFrameModule=pageModelMap.modelMapData.module.iFrameModule/>

instead of 

pageModelMap.modelMapData.module.IFrameModule        (Correct one)

Which is strange since the class' insternal name starts with a small "i"

@HippoEssentialsGenerated(internalName = "imc:iFrameModule")

@Node(jcrType = "imc:iFrameModule")

public class IFrameModule extends AbstractHandlerModule { }

 

Perhaps some issue with name resolutions of modules starting with "i". 

oh well..

Thanks @Jeroen and @Woonsan

FreeMarker finds properties by standards Java Beans API. So when you use ‘something.foo’ it actually invokes ‘something.getFoo()’ getter method, or ‘something.isFoo()’ for [Bb]oolean property.

When you use ‘...module.IFrameModule’ which getter method from ‘module’ instance is supposed to be invoked?

Could you copy and paste the method signature?
