Doubts about using model hints

[Sergio Ramazzina，修改在11 年前。]

Hi all,

I'm new to Liferay and I need some help to understand why some things seems not to work. I'm developing a series of portlets and I'm trying to use model hints to set the width of text input fields or to set the width and height of some texarea fields. I carefully read this blog http://tinyurl.com/d7rhlgk that explains how to set all these things but my portlet form fields seems not to understand these settings. Am I missing something? I've also tried to go through the source of the site portlet where the textarea fiels that contains the description of the site has width and height set the same way but I don not understand why mine seems unaware of these settings and sets the textarea size to default.

Here it is the code I put in portlet-model-hints.xml

    
                  <field name="name" type="String">
			<hint name="max-length">64</hint>
			<validator name="required" />
		</field>
		<field name="description" type="String">
			<hint name="max-length">255</hint>
			<hint name="display-height">105</hint>
			<hint name="display-width">500</hint>
		</field>

Other question anyone can explain me how does work the <validator name="required" /> tag?

Thanks a lot for the support

Sergio

What exactly do you need..in which you are facing probs..?
Check you are building the service again after modifying the model-hints.
ensure that it reflects in your Sql folder..

Thanks

Sorry if I explained my problem uncorrectly. The hint

           <hint name="max-length">64</hint>

worked properly changing the size of the varchar field as required in the generated table SQL. The hints that didn't worked were

            <hint name="display-height">105</hint>
            <hint name="display-width">500</hint>

that changed the displayed size of the input control in the generated portlet. But I found the why. I was using it with the aui taglib instead of
the liferay-ui. The thing that I don't understand is that if I look at the code of the site admin portlet for example it uses the same hints to set the size of a
textarea box but using the aui taglib. So why is it working there and not on my portlet? What am I missing?

how to work with custom portlet for permissions??

[David H Nebinger，修改在8 年前。]

What does custom portlet permissions have to do with model hints?

Have you checked dev.liferay.com where there are learning paths for resource and portlet permissions?
